Re: LS1 No start conditon

Have you confirmed the fuel injectors are pulsing and have adequate fuel pressure?
yes to both questions. Even pulled the fuel rail and visually confirmed the injectors were pulsing fuel.

Also could be a problem with the crank sensor. If the harness is an aftermarket, I have ran into the crank sensor plug being pinned wrong. I can't remember for sure but I think the sender wire and ground wire was backwards. But if your getting spark it may not be in the crank sensor.
Harness is a professionally converted stock harness. Only aftermarket parts were the short harness to the coil packs.
I plan on confirming the wiring to the computer from the crank sensor today.
If I have time I will confirm using a scope.


May also check to make sure you still have ignition power while the engine is cranking.
Used the noid light and pulled one plug to confirm the spark.

This is a tough one. I am confident the cam was installed correctly. Hoping to confirm that with the compression test today.
Appreciated you diving into this one. Open to any suggestions.
