So the mystery deepens. Car randomly won’t start but turns over. Thought we figured it out yesterday and it was running fine. Whoever installed the vland headlights used the ignition fuse to jump for the drl and once we took that off car started right up.. Go to start today and nada won’t start.

3 weeks ago the issue started. I didn’t hear fuel pump priming so ordered a new fuel pump and issue was fixed. Car ran perfect for 2 weeks then it does the same. I take it out and there was some questionable wiring done so I ordered a hanger and use the factory wiring to splice the pump and nothing car still won’t start. It’s so random too sometimes it starts some times it won’t..

Talked to the guy I bought it from today he said last year he had same issue. Got a new fuel pump and had a shop do it and never gave him issues after that. I have checked all the relays, grounds, etc and have no idea what to even look at anymore


does seem cold weather makes it worse.

 

when I had that issue before an engine build, it was the crank sensor. I tried a few. it needed an additional very thin washer to line up properly.
try disconnecting the clutch pedal switch and try to to start the car without pressing the clutch. (or the opposite if you already start the car without pressing the clutch pedal)
