Hey all,

Been having some troubles for a bit finally getting at it. Left a track event last fall and my car stuttered and shut off. Started again - 10 min later stuttered and shut off. Trailered home and if starts right up just fine -
Next day not at all! So I replaced my fuel pump while double checking my work with the basket out. Still having same issue- anyone ran into something like this? It worked day 1 with new pump day 2 the pump won’t kick on so I have no fuel pressure etc. such a flaky on and off situation I’m pretty stumped on this. This is all with the car not moving just parked in my garage so nothing is shifting etc. possible ignition system/ecu issue?

I don’t see a wiring problem anywhere, not a fuse…any advice or ideas on this one would be great
.
Car is supercharged with ecutek tune/1200cc injectors/deatschwerks pump and pump wiring kit.
