Gremlins
Gremlins Ok, where to start.
I finished up most of my wiring on my swap, I got a body control module from another member here on the board, and wired that up.
When power is hooked up fuel pump will come on, but when the engine is starting and running the fuel pump wont run. The motor will die almost imeadiately. If I bypass the relay it runs fine for a few seconds until the anti-theft kills it. Should I just run the relay off the key and say screw the computer?
Then it leads me to my next problem. I have the BCM hooked up, it came with the ignition cylinder, and a GM key with the chip in it. I dont think it is the right key for the cylinder, because it wont turn in the cylinder (unless I'm an idiot and cant figure it out) =). Anyway car starts and will still die after a couple seconds. I checked the lead going out to the computer and it is showing 5 volts. I dont know how the check to see if it is putting out the 50 hertz thats needed. Any ideas on this one?
Sorry about the length of the post. Any assistance is greatly appreciated.

Re: Gremlins That should be the correct key - I bought that BCM setup the guy that sold me the motor. He had it wired up and started the motor for me before I loaded it up. Ran for at least 30 seconds that way. I think that whole cylinder turns within the lock mechanism.
You might try checking the grounds to the PCM. Also, there's 2 dark green wires from PCM that look identical - one is fuel and one is the Data line. I had those crossed on mine initially.
I don't think the pump is meant to run continuously.
I presume you have the blue wire on the BCM running to the PCM (I think the PCM wire is yellow/black?), 12v+ going to the pink wire and the black wire(s) grounded?

Re: Gremlins Im just trying to get it running as cheap as possible right now. I dont know the first think about making my own Vats module, so thats not really an option for me.
