Long story short took the misses too hospital the day comes out car woundnt start, rings breakdown they tell me they dont no what it is :angry: ( all he done was pop the bonnet and just look at it)
Its currently in the garage but they cant even get it started, its been scanned threw up a few codes which was on it before it wouldnt start, no new ones, changed oil sensor as that was 1 of the codes, the other 2 codes were speed sensor and camshaft position sensor, would any of these stop it starting or is it something else thanks in advance for any help
-
couldnt imagine them stopping it starting.
i know my cam position sensor was throwing up a code on old car, that only seemd to stop me starting it when it was warm and even then after about 10 seconds it would start...
speed sensor i would assume is the sensor on the wheels, again cant see that stopping it starting...
-
Thats my thought with them codes mate researched everywhere and theres nothing too say they would either, no other codes so im plucking at straws, anything common on these to stop it from starting, fuel pump etc cheers
-
id check the simple things first. are you getting a spark are you getting fuel is the starter motor turning etc...
-
Not sure on all those mate as its in the garage i would have thought they would have check them but ill give them a ring and find out now cheers

ask if the timing belt is ok :smiley:
-
Just spoke to someone who works there says its not the starter and that they are still looking, its been there for 3 days and thats all they can tell me :angry:

took vw less time to build it :evil:
-
Lol i probably would have found the problem quicker than them and i no nothing about them :grin: bloody useless they are
-
I had a faulty engine speed sensor on my 51 plate gti turbo its the one that screws into the block nearly your oil filter my car wouldn't start changed it for a new one all fixed runs perfect now i take it your car is a mk4 golf :whistle:
-
Yea its a mk4 will it be in the same place for the 2.0? If so maybe it came off after changing oil filter or broke a wire ill get them too take a look now cheers mate
-
Keep up posted as one of are friends as the same fault on is a4 :smiley:
-
Yea will do mate ill let the garage no what u said when he opens tomorrow hopefully it is that if not back to the drawing board :sad:
-
6 days and still cant get it to start :cry: Starting to lose patients with it now, some people have said something about the ecu might be gone or sonething, what do u guys think cheers
-
Speed sensor in this case is the crankshaft speed sensor as baxxy quite rightly said. This is your problem.
-
most likely but also listen for fuel pump operating. take fuel cap off,stick your ear to it and get someone to put ignition on. very easy test.
-
As far as im aware mate its been checked/changed by the garage not 100% sure on that i have vw going there on monday too have a look themselfs, im lost without it lol It cant
-

The garage still has it at the moment mate, waiting for vw to go there on monday then if they dont no im getting it back to have look myself so i could check that then cheers
-
Crankshaft sensor changed, fuel pump sounds like its working still wont start, what else could it be? Any help very great fully received thank you
-
Are you getting fuel and spark?
-
Not to sure mate how would i check both ( not very mechanicaly minded) :whistle: ive got a new ignition coil coming now to try too see if its that cheers
-
New coil pack fitted still wont start im slowly giving up :cry:
-
did the garage do a compression test? and can you get a copy of the fault codes?
-
I dont think they did mate and no cant get a copy mate as they just deleted them :angry: and cant scan it again as my laptop is broke could my cat have anything to do with it?
-
Any other ideas on this please guys?? Could this be my cat causing this or is it something else cheers
-
Have you or the garage actually replaced anything yet?
-
Yes mate new oil sensor, new camshaft sensor, new crankshaft sensor, new coil pack still no luck dont no what else to change cheers
-
Does it fire up and then die or just won't start at all?
-
Does it turn over but wont start? has anyone even tired looking at the state of the spark plugs? :undecided:
-
It just turns over, it had recent spark plugs and leads approx 4 months ago, will the cat stop it from starting as that needs replacing as it has started breaking up, was going to have it done until it died on me lol
-
no it wont, my Mk3 blew the cat and backbox, and still drove fine lol
However, the Mk2 my cuz and I were working on, we changed the head gasget and used a 3rd party timing belt and it was like 2 teeth out and until we sorted that it would not start.
-
the cat would need to be blocked solid to prevent the car from starting, i doubt that's happened but you can unbolt the downpipe and see if it starts to test.
-
Ill have to take a look tomorrow now as i think my starter motor has gone as well as it just clicks when i go to start it :angry:
-
or your battery is very flat
-
Its a brand new battery mate only bought it yesterday lol
-
Has the garage checked the earthing straps? Fuses on top of the battery?
-
To be honest Mate i dont think they checked anything apart from change the oil sensor as the light was on, because when i was telling them to check the things i was told to check they kept saying it wasnt that
-
They should have nailed the problem by now though :undecided:
-
I thought that mate thats why i had it back 2 days ago everytime i went down there no one was touching it, i was just getting told they were waiting for someone else to come and have a look but they never turned up, :whistle:
-
Had another look at it today, to see if i was getting any spark (basically checking what the garage should have) so i put a spark plug on the ignition lead with a jump lead from the spark plug to battery (thats what i was told how to do it) lol and cranked the car, didnt see no spark cant be 100% As my battery died, waiting for a mate to come and put some life in battery for me to double check, if there is no spark were should i start looking to fix it? I was told live wire to the coil pack may have broke what do u guys think cheers
-
First try it with a healthly batt, put the spark plug with the coil pack connected to it near a metal serface, you should see a spark on turn over it should do it in rotation of 2,4,1,3 i think.
if all 4 are sparking well, then id say you might have a fueling issue, check your fuel relay, fuel pump, I.E when you open the drivers door or put on the ignition do you hear the pumps prime? (wont do it all the time usally after the car has been standing an hour or so not being used)
-
Just put my mates battery and still no spark from any of them, Fuel pump primes up so dont think its that, is there anyway to bypass a wire to the coil pack to see if theres a break in the wire or some thing cheers
-
Checked fuses? Relays? And get a multi meter on your coil wires
-
Ive checked fuses and relays all seems ok i dont have a multi meter, but will see if i can borrow one, may be worth noting that before it all happened a car crashed in front of me and something came off his car and went straight under mine, it punched my sump and broke the wiring for the oil sensor, ive had that redone, but could it have broke a wire further up or something cheers
-
Checked all fuses and relays?
-
Me personally not but that was what the garage was supposed to have checked first, i can double check tomorrow, Is the relay behind the fuses on these? Cheers
-
How do i check if the relays are ok also just bought a cheap multi reader to check the wires, how do i use it lol, sorry if its a stupid question but i aint got a clue :whistle:
-
Can anyone tell me what relay to check please
-
Right no spark at all, all fuses are good, relays seem fine, got a reading on the multimeter of about 68 on them, checked the wiring and the highest was approx 700 ohms or whatever u call it lol, which i thought was on the low side, maybe worth noting that the revs go up to the first white line whilst trying to start if thats got any relivance to it? cheers
-
No chance of getting any fault codes read from it? The vague description of the codes you gave in your first post could be nothing or could be catastrophic. Where abouts in wales are you? Close to Rhyso in merthyr?
-
No not far 5mins from him, i have spoken to him and he said that it might not be any codes there as the garage had deleted them, hopefully ill no more tomorrow as i have diagnostics coming out, as im lost without her :cry: so with a bit of luck it will be up and running tomorrow or i will atleast no whats wrong :smiley:

Where are you then? I thought you said Cardiff :undecided:

I live in rhymney mate :smiley:

Oops :embarrassed:
If the bloke cant help you out give me a shout :smiley:
Which garage did you take it too out of interest? :huh:
-
Ok cheers mate will do and i took it to a1 autos :smiley:
-
it doesn't have to run, you can sometimes learn enough from the codes generated just by switching the ignition on or cranking the engine.
-
Just had diagnostics out and he seems to think my ecu has gone, What do u guys think? It did have some water damage/corrosion under the plugs as it was green if so how much to get another 1 coded in cheers

this happened to my car got a spare ecu off a mate but seen loads on ebay for sale or find a car breaking near you :smiley:
-
Yea seen a few on ebay, just making sure it sounds like an ecu failure as ive spent alot on it the last few weeks with no results, do i need to match the part number, cheers
-
Yes your part number needs to match exactly. They are fairly easy to code in, I'm sure even Rhys could do it
-

pretty sure you do i did with mine an they are not that expensive its coding them in the was the dearest part :smiley:
-
Yea just matched mine up on ebay, and theres 1 there for 17.50, but the man wants 180 just to code it in which i thought was a little expensive but im not clued up on things like this, cheers
-

it cost me 50 quid to have mine done so 180 sounds a bit much maybe some1 else can do it :smiley:
-
I thought it was a bit much to just code it in, when im supplying the ecu, but im sure he mentioned something about bypassing something im not sure :undecided:
-
What does he think the ecu is gone??
-
Im not sure mate, he gave no real explanation as to why he thinks its that apart from the water/corrosion damage to it cheers
-
What does he think the ecu is gone??
are you not near this guy :undecided:
-

are you not near this guy :undecided:
Yeah and your point??
-
Im not sure mate, he gave no real explanation as to why he thinks its that apart from the water/corrosion damage to it cheers
Did he tell you if there were any fault codes?
-
What fault codes came up?
-
All the 1s that was there before, crank shaft, cam shaft, lambada, oil sensor, and speed sensor, but they have since been changed :smiley:
-
immo2 takes 5 mins to code in, immo3 is a bit more involved as you have to code a few more bits. £180 is a bit much though especially when the instructions are listed on the Ross-Tech website lol
-
I dunno if your ecu is broken, were your old codes cleared after you had the parts replaced?
-
No mate they wasnt cleared couldnt get anyone to do it, my oil sensor light comes on all the time, and that has had a new 1 fitted
-

If they were not cleared first of all then they would natually show again ehen scanned
-
Yea i thought that lol, hes cleared them now but im still getting the 1 for the oil sensor :undecided:, im going to order a ecu now just incase hes right, as ive changed almost everything else lol, but going to see if i can find someone alot cheaper to code it in as i dont want to pay £180 and it still dont work :smiley:
-
Before you buy an ecu have you tired to bump start it?
-
No aint tried to bump start it mate its parked at the bottom of a hill and dont have anyone to push it with me, also hes taken the ecu with him to see if he can repair it or something
-
Oh
-
Can someone do me a MASSIVE favour and tell me what can stop a car from sparking? After changing everything including the ecu, crankshaft, leads, plugs, coilpack i still have no spark, all fuses good, going to check the wiring tomorrow for brakes but just looking for a list of other things that will stop it from sparking, as its been a month and cost alot and getting no where, anymore help is much appreciated thank you
-
I havnt read through your thread but have you replaced your ignition amp yet?
-
Sorry for the stupid question but im not clued up on cars but what is it and were will i find it cheers
-
Its attached to the air filter box with plugs both sides.They turn the signal from the crank sensor into a switched signal capable of inducing HT in the coil. A failed amplifier will stop it sparking.
-
Ok cheers mate i aint checked that is it on all mk4s as mine is a 2.0 aqy thanks
-
Not sure tbh I thought you had 1.8t :laugh: worth a look fella
-
I wish it was mate but the insurance is too much lol no worries anyway mate ill take a look tomorrow cheers
-
Anyone else with some more ideas for me please as to what else can stop it from sparking cheers
-
You tired the amp yet? if you got one it will be bolted to your airbox
-
Ive checked on my air box mate cant see anything bolted to it so i dont think i have 1 lol
-
After a full solid month of changing and trying various things FINALY it started, turns out its the black and purple Wire going to the coil pack wasnt giving it enough power to make it spark, any ideas why? I was thinking a break in the wire but it is getting some power is there anything else it could be? Cheers
