So i recently fixed a no start ignition modual problem on my car. I have however had the whole harness unrapped and checked every wire in the loom for ohms... that being said the car is running like a champ now untill last night i droppen it in 1st(700r4) and gave er' hell and around 3500for rpm she just shut her self off like she was saying im done... luckley i was going down hill and when i slowed down enough she came back to life. I then put it in nutral and the same thing happened... no heart beat after 3500rpm for like 2 seconds and then boom back on running at 2g. What the hell is going on here? I know halloween is around the corner but i didnt know cars could be possesed... maybe its a transformer! Lol anyways im going out in a sec to make sure the harness plug bolt is tight all the way down.

 

You have to figure out what you are losing.
Start with...
fuel pressure check while its acting up.
spark while its acting up, use an inline tester.
injector pulse. Get a noid light.

 

Luckaly i have my own noid lights and i already know all my circuits are good from pulling my wiring harness out. But its just what i thought it was. The bolt for the harness was loose and a quick fix. Runs beautifully now. Shes alive!!!!
