Wrecked, trying to crank
I bought a wrecked c-4 1995. I bought it for the running gear but would like to hear it run before I take the motor out. I can put a hot battery on it the lights on the inst. panel light up but when I try to engage the starter nothing. Is there a safety switch somewhere that won't let it crank if the airbags have been deployed ?? If so , how do I bypass this so I can crank it ?

Can easily bypass the starter enable relay as noted but all you will get is cranking
Without the correct key or having VATS deleted in the tune
( read http://www.thirdgen.org/vats_passkey_system )
the PCM won't pulse the injectors so with no fuel it won't fire up
Edit
What are you putting the running gear into ; you will need VATS deleted anyway if not going back into a similar car with a VATS module or CCM

Vetteoz, I'm thinking that's the problem, the wiring won't let me crank the car since the airbags were deployed. The owner when it was wrecked stated when I bought it that as soon as he wrecked it he couldn't crank it back to move it. He also got some Bar Room buddies and took some wires loose trying to get it to crank.

find the Main SIR module, unplug the connectors.. there should be 2 heavier gauge wires ~12ga.. jumper the 2 together and try it.. that supplies power to the ECM, which I am guessing is not currently getting power
