Help.. 67 camaro w/ lsx454 swap.. Starts but dosnt stay running..
Alright guys. I have a brand new crate motor all wired up in my 67 camaro. Brand new Gm lsx 454 motor, fast 102, nick Williams 102tb, 57lb fast injectors, psi engine wiring and 07 vette ecu, Dynatech 1 7/8 open headers, ctsv vapor worx set up. The car starts but won't stay running, fires for 2-3 seconds then dies. I thought it was my coil pack wiring but I made sure that was correct tonight. All my sensor are plugged in and brand new other wise. When I turn the key I can hear the fuel pump priming. The pedal is hooked up if that matters. What should I be checking next to start figuring out what is the problem? I've read a dozen threads about the vats being turned on/off. What are some things that would lead to me guessing if it's turned on? Can I check that with a scanner? Also should the check engine light be on when the key is on run? I'm going to try to get this video up any help is extremely appreciated. Thanks Steven

I would have to say yes. But at the moment Im trying to get a hold of a scanner to check to see if it has or not. I am also waiting on john from PSI to get back to me on this. Could it be anything else? Thanks for the reply.

Try spraying a little carb/choke cleaner in the throttle body while attempting to start. When I put my 427 in my trans am with all new fast fuel rails ect. it did the same thing till I kept it running for 20-30 seconds on the spray. For some reason it seemed like it took awhile to get all the air out of the fuel system so it would stay running on it's own. Mine has been fine since the initial start up.
