Hi. Just tried starting my LS that I installed in my 83 Camino, and I can’t get it to start yet.

The fuel pump primes, and I have fuel at the Fuel rails. I checked the pink wires to the coils, and they have power.

I am a noobie to these LS motors. So I am looking for some help troubleshooting why it won’t start. Not sure what else to look for and check

Thx
Shannon

Sounds like a VATs problem. If you have a 'Noid' light unplug one of the injectors crank & see if you get a light. Won't get an injector pulse if VATs is still enabled. Same if the crank sensor isn't hooked up. Ask me how I know

Does it start and die?
Is the VATS disabled in the tune?
Are all the unused vacuum ports plugged?
It won’t start at all. I did send the computer away to lt1 swap to have my computer done

Thx for answering
I just went and bought some noid lights

When I turn the car over, there is no flash. But when I release the key it flashes once.

The ports are plugged. And the computer was done by Brendan at lt1 swap

I just tested the pink wire for the coils. And they have power with ignition. But nothing when the engine is being turned over

So no injectors or spark while being turned over
