- let car cool down, prob 30 mins. Started car, cut out immediately. Felt ignitor, it was cold.
This is making me consider it isn't the ignitor.
2nd thing I did was pull the TOMS ECU. I found brown liquid stuff on one connector of the 5 connectors of the TOMS ECU. I thought this would be the problem. So I clean up the connector, and put in a STOCK ECU inside this time. Car still cut out. Damn.
I took apart the TOMS ecu, didn't see any components leaking. Odd.
Spoke to my mechanic, said check sparks, HT leads, ignitor, coils. He then said I'd have to check the fuel pump after this...
I will hopefully check by next week, although if we presume something is heating up and failing, then it tend would rule out the ignitor as this was stone cold and the car still failed to start. The car then started fine the following morning. It could still be the ignitor of course but it's an outside chance. And I think I can rule out the ECU also.

Have you ruled out the Air temp sensor?

About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information?
