1970 LSCamaro

I tried to fire my 6.0 in my 70 camaro today......it fires right up then dies. I have sent my PCM in to big 3 racing to do a start tune before I take it to them.

I used a Diable scanner to read my codes....they are:
P0522...Engine oil pressure sensor / switch circuit Low input

P1518...Intake manifold runner control stuck open bank 1

P1638 CAN LINK ECM / INSTM circuit network


I have verified that my ignition wire stays hot after releasing the key, and it does. I verified that the fuel pump relay stays hot after the motor quits, and it does.

I changed my idle air control in case that was it, and it wasn't.

What am I missing here guys????? Please help, I want to fire this thing up!!

Sounds like a VATS issue. That's exactly what they do.

According to my tuner, he took the VATS out.

Do I need to let the fuel pump build pressure, then purge it with the fitting on the end?

I also have read on here that I may need to use starting fluid to keep it running til the ECM figures out where it is.

Is it true that the VATS could have reset itself since I didn't power it up for a month or so after getting it back from the tuner?

Mine fired right up with now issues on my swap. Had vats and emissions deleted and that's all
