1968 stepside with 2007 5.3L starting system wiring???
I have been building a 68 stepside with a 2007 5.3L/4L60 setup for to long now..LOL. I was just finishing up the wiring, I though, and now I am unsure of the starting. A little brian storm--- the PCM enables the starter when it sees everything is good. The problem I am facing is the PCM won't see the ign. input because I am running the 68 ign. switch and the 2007 ign switch feeds into the BCM and then the BCM relays the message through GMLAN high speed network. Now if I just feed the starter enable circuit from ign switch will it start.. I know I will need to dissable Passlock and other stuff, I have EFI Live to do that, but at this time I am just worried about the wiring..
Thanx for you input guys..

checked power and ground to pcm and both are good. Checked power and ground again to coil and it is good. Also have good power to injector while cranking. Something is telling the PCM not to fire........ There has got to be more to this operating system with passlock then just turning it off with EFI Live....

I have the same problem. I'm running a 2007 5.3L L59 vortec engine and I think I've got everything wired up correctly. There's a little fuel that sprays immediately when I turn the key to crank, but it only happens once and after that, the fuel injectors will not turn on. It's like something is telling the injectors not to open. I've got 58psi at the fuel rail and I'm running pretty much all of the emissions systems stuff.
It seems like most of the people here are talking about turning off VATS. But, then I'm pretty sure their engines are older models (or engines flashed with older PCM configurations). I'd like to hear if someone that has worked with a 2007 or newer engine has been able to figure this out.

I don't have experience with the newer e67/38 pcm's yet but do a little lurking since I'm sure I'll swap one in the future...
