I just bought a 2000 Camaro roller and swapped in a motor. The engine starts and runs perfectly fine - but only if I jump power directly to the injector fuses at the fuse block.

So for some reason, the fuse block isn't getting power- but the weird thing is, everything else on the fuse block is getting power, just not the injectors.

any tips?

Vats maybe?

VATS is disabled in the tune, but I've been reading that it can still exist even if it's shown as disabled on the PCM

What is weird is that when I bought the car, it had the original engine in it. It would start fine - and I'm using the same PCM.

Looking at a wiring diagram, it shows a pink wire going from the PCM to the fuse block, which then goes to the 2 fuses for each bank of injectors. I'll make sure these threes fuses are'nt blown (already checked all the fuses, but I'll check again). At this point it looks like the PCM isn't sending power, so that all points to VATS I'm guessing

PCM doesn't send power to the injectors. The pink wires going to the injectors and the coils comes from a 12v ignition source. The PCM grounds the injectors..

Oh, now that I look at the diagram again, yeah, I was confusing myself. I jumped to conclusions thinking that the PCM must not be putting out 12v to the fuse block, but in reality the power is going FROM the fuse block and TO the PCM

Also, I'm pretty sure that they are fused in a bank 1/bank 2 order, so Bank 1 coils and injectors are fused together, and bank 2 coils and injectors are fused together.

If would be impossible for only the injectors to lose power. You're either losing power to a single bank, or losing power to both banks of injectors and coils.

It ended up being the ignition relay installed backwards lol

Hey man i know it's old but I'm having the exact same problem, but i was driving and lost power. I'm not getting power to the pink wire to the fuse box to injectors.
