I AM SO PISSED OFF AT MY CAR RIGHT NOW!!, @@@@

[GOLF-MK3-GTI]

Right people this is the probelm, I am so confused on what is wrong with it, and i am loosing my patience with this car, Please help..

Yesterday i spent most of the day cleaning all the earth wires on my car, i also cleaned the one's under the battery tray,i replaced the earth wire from the coil to the engine with a new one.

i then got a new coil from GSF, its a good quality one as it has VW & Audi badge stamped on it, anyway i also replaced the roter arm and distrubutor cap as the old one's looked tired.

I took my car from a spin and i've been driving last night, Cleaning the earths have made a lot of difference as my lights have become brighter and i can see where i'm going on a night, lol.
yesterday i turned the engine off about 8 times and started it again and it was perfect.

today morning i started it and it started, been driving it all morning without any trouble.

Right this is the problem,

I parked up in my drive, was going to go out half an hour later, tried cranking it, but wouldnt start, i unplugged the ECU Temp sensor, still no joy, i unplugged maf, still no joy,

I then had my doubts on the coil as i took of the lead that comes from coil into distrubutor and it didn't spark, so i thought its the coil, anyway i had a spare coil in boot that works, so i tried that, but again it did not spark.
I then left the car for half an hour, came back and it started up first time

so now i am thinking if theres no power going into the coil at all, then how will it spark.

I have my doubts on the ECU Relay, No: 30 or could it be the ignition switch?

have any of you had problem like this? Please help.

Could be the immobiliser or the afore mentioned relays.
Change the relays first, they can be had for under a tenner each.
Also try the spare key (if you have one) as the chip can get a bit tired, or take the chip out and tape it to the transponder around the ignition switch, see if that helps...

Totally daft question but the battery is fine isn't it?  Have you checked?

[GOLF-MK3-GTI]

lol, yes the battery is fine, 2 days ago it was used to start a vauxhall astra diesel.

And as far as i know if it was the immoboliser, then the car would start for 1 second and cut off, but i will try the sppare key, and this problem only ooccurs when the car is warm, but sometimes only.

That's if its working properly

[GOLF-MK3-GTI]

I think the immobiliser works properly, because when I unlock the doors, the yellow light shows, and then after a bit it turns red, and if I try to start when red, it does nothing, unless I press unlock and then it shows yellow light, which then enables me to start the car

could this show if it's working?

Anything is possible, you say you think the immobiliser works so you obviously are not sure....
There in lies the nature of trouble shooting.
You need to work through from where you stick the key in to where the spark jumps out, obviously you can help yourself a lot by plugging it in to a code reader and checking for fault codes and a reset.
Worth looking back through the site history as this is common on Mk3's
