fitted the 1.8 back in a few days ago got everything wired up ( at least i think its all in properly) the car will turn over, and sparking but wont "run" cant see anything visibly wrong with it, just not sure what else it could be. the timings ok,its getting fuel and a spark, weve checked that, but dunno where else to look now, can anyone help or gimme anything i should check, or if anyones local to me who can come and have a look itd be mucho appreciated
thanks Sarah

digifant or K-Jet ?
-
check your timing.
-
timings spot on, and its a 1.8 8v so whatever that is, i dont really know a lot about the engine codes lol
-
So have you replaced your mk3 2.0 8v for the origional 1.8 8v engine? K-jet is the mechanical injection and has the braided wires on the air box. Digi the electronic type and has an electrical sensor on the intake hose. If its turning over really quick its usually a snapped timing belt or even worse, internal damage. Whats the history of the engine? Whats it from? Was it running before?

yes its been replaced for the original. its not turning over really quick, the timing belt is intact, im not that thick!!!!!! the engines from the car we bought and it was running before we took it out of the car

The timing could be 180deg out, you would still get the spark near to TDC but it would be on the exhaust stroke rather than the compression stroke. The piston would still be at the top of the cylinder but the valves would be open rather than closed - this is a very common error. :wink:
-
my fiance had a feeling it could be this cos we had to change the distributor cos the one on it was fooked, any way i can do it or tell if its wrong?
-
Well this is how I would check:
Follow the No 1 cylinder plug lead back to the dizzy cap and make a note of which one it is.
Take the no 1 spark plug out (you could take them all out to make the engine easier to turn over) and turn the engine over by hand and watch for the No1 piston to come up to its highest point.
Take the oil filler cap off and I guess you should be able to see the No1 cylinder exhaust cam, if it is pointing down then your on the tdc exhaust stroke so turn the engine over by hand again 360 deg until the piston comes up to the top again and the cam is not pointing down. The piston is now tdc on the compression stroke.
Now take the dizzy cap off and see in which direction the rotor arm is pointing, if its not pointing in the direction of where the No 1 lead was and pointing in the opposite direction then the dizzy is 180deg out. :smiley: I expect someone may have a quicker way to do it??
-
ok this may sound silly same happend when my gti engine was put in basically it was a earth lead to the gearbox but check them all ! u never know! :smiley:
-
had the same with mine it was 180 degrees out do the later and it will be sorted!
:grin:
-
Would do as Jezza says as sounds like timing is 180 degrees out, you can swap the plug leads over at the dizzie, the firing order should be 1.3.4.2.
-
check your timing.
knew it was timing. im a clever boy lol. hope you sorted it!
-

can sumone explain better for me plz
-
ok cylinders are numbered from the left hand side. firing order is 1342. no1 should be connected to the bit on the dizzy cap nearest to pointing to cylinder no1 in a straight line. then in a clockwise direction attach no3 lead to the next post then no4 lead to the next one then finally no2 lead to the last one. im going from memory here and im at work so i may have not got that 100% but in the distant past i have done this and im struggling to remember lol im sure i will be corrected if im wrong! u got a haynes manual??
-
Take out spark plug #1 (left of engine, nearest timing belt) and turn it over by hand till cylinder #1 is at the top of its travel. Then remove the dizzy cap and check where the rotor arm is pointing, the rotor arm should be pointing at a notch in the dizzy, which should correspond to spark plug lead #1. If not the intermediate shaft has moved, its free to spin when the belt is removed.
You can either loosen the timing belt and adjust the intermediate shaft sproket, twist the dizzy till the rotor arm lines up with the notch, or you can move the spark plug wires round so that the arm is pointing to the lead which runs to cylinder #1, then fit the rest of the leads in sequence 1342 clockwise :)

Correction to the above, the cylinders are numbered 1,2,3,4 from the left hand end of the engine looking into the engine! :wink: Also the #1 piston must be at the top of its travel on the 'compression' stroke, the key is knowing when its at the top on the compression stroke rather than the exhaust stroke. :wink: :wink:
-
sorry i meant that was the firing order. it was the start of a new sentence so
cylinders are numbered etc etc i will modify it lol
-
im gunna have to write it down and go outside and have a look, grr damn engines theyre a nitemare :cry:
-
its also just occured to me, my 2.0 8v was apparently running on a 1.8 ecu, however ive never checked this, and i was wondering, will the ecu be different between the 2.0 and 1.8 cos its still got the 2.0 ecu in it, we didnt take the ecu out of the other car, totally forgot about it and scrapped the fooker in :cry:
-
you never heard of a printer?  :grin:
-
you never heard of a printer?  :grin:
yeah but thatd be the easy option :grin:
-
the 2.0 ecu wont even plug into the 1.8 loom, the 1.8 ecu is what you should use :)
-
jonny ive never seen the firing order typed so many times on one page let alone on one thread!!??lol
what is it a again?and from what end?lol
it can be a nightmare i timed mine in that firing order back the other way!!lol and it ran mind you that might have sumik to do with no4?or is it no1?had a hole inm it! :sad: :grin:
-
the 2.0 ecu wont even plug into the 1.8 loom, the 1.8 ecu is what you should use :)
so my 2.0 has always ran on a 1.8 ecu then :rolleyes: no wonder it was sh!te
-
well ive done what everyones said to no avail, somebody correct me if ive done it wrong.
took #1 spark plug out and turned pulley til piston was at the top, stuck a screwy in it, undid the dizzy and turned rotor arm til it was pointint at #1 spark plug, and followed the following firing order from left hand side of rocker cover
#1 #3 #4 #2
the corresponding lead went onto the dizzy cap in this pattern anti clockwise 1# top left, 2# top right, 3# bottom right, 4# bottom left
is that right? can anybody correct it with a pic if its on wrong please?
really annoyed now :cry:
-
No no no ;)
the pistons are ordered 1, 2, 3, 4 left to right. The firing order (i.e. the lead order on the DIZZY) is 1, 3, 4, 2.
-
ahhhh i c * scratches head* will go out and have a bash and then ill take a pic, and if im still wrong then i think ill smash the fookin thing up :angry:
-
so starting at the top of the dizzy cap, which way do they go on, in CLOCKWISE direction?
-
clockwise yep :)
-
well ive done it that way and that wont work, its turning slower than it was now
explain it step by step????
#1 on the head goes where?
and same for other 3 :angry: :angry: :angry: :angry: :angry: :angry: :angry:
-
#1 lead, runs to the dizzy terminal which matches up to the notch in the dizzy housing, or where the rotor arm is pointing when the engine is at TDC :)
Check the line on the crank pullet lines up with the arrow on the cambelt cover, and the punch mark on the back of the cam sprocket lines up with the top of the head with the rocker cover removed.
-
if your timing is right. check your ignition moduel (the thing that sits ontop of the ecu)
ive fried mine 4 times :laugh:
-
leads on the dizzy cap #1 top left, #3 top right, #4 bottom right, #2 bottom left..try that. Come back if it does not work.
Engine turning slower could mean the battery is getting flat!

Just to clear up ALL the confusion:

thats bloody good that RJ!!!! :laugh:
have you ever thought of trying out for BluePeter!! :wink:

fookin lovin the picture!!!! gunna do that now, and come back when it dont work again lol
-
no joy at all, still the same as it was, im ready to give up now mind, if my mate dont fix it tonight i may get the angle grinder out :angry:
-
does the fuel pump prime? Does it stink of fuel? Getting a spark?
-
and the plugs/leads/etc are definately in good nick?
-
yep and yep, plugs are soaking, and its sparking but just not firing!!!!!! got magnecore leads on and plugs are fine too :cry:
-
so when you turn the key 1 click the pump runs for a few seconds then stops?
-
OK, a last resort here.....  Lets assume that the dizzy is located 90 or 180 or 135 deg out to the standard.
1.  Check the leads going into the cap and double check the clockwise order is 1324,1324,1324 regardless of where the #1 lead is plugged in.
2.  If the above is true, unplug the leads from the top of the dizzy cap and move them all 'clockwise' by one position, (they will still be 13241324 but shifted through 90deg) and try again........
3.  If no go then move them all clockwise again by one position, (ie 13241324 but now shifted 180deg) and try again.......
4.  If no go then move them all again by one position clockwise (ie now 235 deg shift) and try again. If no go again, get your angle grinder out!!!!  :wink:
-

yep and plugs are soaking when you take em out
-
same problem i had...............................
bad earth or blue sender needs changing.
-
can anybody give me a list of where all the specific earth points are on a mk2 8v?
-
one to the gearbox, several to engine block to the flange on the RHS and the rocker cover, one from coil to rocker cover several on the battery.
Put a new blue temp sender on as it will never start with a broken one.
-
(http://img.photobucket.com/albums/v197/Slick13/firingorder.jpg)
same as on an 8v i presume. Oh and cylinder 1 is the one closest the drivers side wing.
-
nah slick the firing order is the oposite way round on an 8v, we've already covered the firing order pretty well I think :wink:
-
Slick - The firing order is still correct for the 16v but the dizzy shaft spins anticlockwise. Re: my earlier post this afternoon, I cocked that up :embarassed: should be 1342,1342 etc not 1324 as stated, otherwise moving the 'lead to dizzy' connectors around clockwise is a quick check/fix if the dizzy shaft is mis aligned. :smug: I think I'm going to find a dark room and have a lie down now!
-
I admit i was being a skim reading f**ksock, and jez, your post confused the tits off me :laugh: :laugh:
-
ahh the blue temp sender switch snapped, will have a bash at that, and got another ecu on standby
-
still not working, fixed blue temp switch, checked and fixed all earths and still no joy :cry:
-
you guys know your stuff and this only a suggestion but if all the above is working have you looked at your igntion relays as if you have all the above spark ,fuel and the likes you will still turn over but nothing without the correct relays i will now go back to my corner!!!!!!
-
what you mean by ignition relays :huh:
-
ill stick with my ignition moduel guess :wink:

thanks Sarah
Hiya, I know it's been covered, but it does sound like a timing issue - I aint no mechanic, but surely if you've got a spark, fuel delivery, and compression, unless the timing's completely wrong, the car should at least attempt to fire? I'm fairy local and don't mind having a look - check ya pm's! Dont give up!
-
i had this with mine as jonny he will tell ya!
turn the engine over until no1 is at tdc ie the bottom pulley mrk is on the arrow on the cam cover.then pull the bung on the gearbox and make sure the tdc mark on the fly wheel is on the marker on the gearbox??if its not then sumik is adrift with the timing???if all is well then its all good so far.
next turn the ignition on as though you are about to start it,then go to the dizzy checking that the rotor is pointing at no1 you will know by looking round the outside of the dizzy edge there will be a notch in it the rotor should be pointing at this!replace the cap and turn dizzy untill you hear a click with turn it back and fourtrh so that youve got it right on the click and then turn the dizzy back(anti clockwise a couple of mllimetres and tighten dizzy.now try and start it?????
this is basically the standard setting if she doesnt fire up theres defo sumik else wrong apart from fueling and spark it would suggest that you timing is all over the place and it could all do with retiming,valve timing,ignition timing and time for a sit down to try and clear you head of all the threats of smashing it up or burning it!lol hope this helps thiis is what i did to mine and she fired up first time after i had set the valve timing :embarassed: :embarassed:
-
well hopefully if mr angry has a look and can check the timings in order then we might be able to get it sorted, i need to get a starter motor though cos think this ones goosed!
