Default Fuel cutoff switch?

I had an accident on track and have the car back ready to start but...seems like no fuel is getting to the engine. Driver's airbag did go off. Car will turn over but not actually starting. I have searched all over the web/forum and cannot figure this out. I just want to start her up! It's been since April! Way too long.

Have you been able to check other potential sources of "stoppage" such as damaged lines, etc?

(btw, there should be a fuel-pump relay to check, as well)

No damage to fuel. I'll double check the relay. All was good before I hit the wall, lol. Front end only damage.

Remove battery ground and positive cables and touch them together and then reconnect and see what happens.

Bill - I always trust your judgement. But can you clarify on this one?

Tried touching the wires together for about 30 seconds. Nothing different.

Guessing it probably has to do with the air bag or restraint system needing to be reset. It probably shut off the fuel pump to prevent fire.

After the car has sat for awhile do you hear the fuel pump prime when you open the driver door?
had same issue on a Chevy truck. Swapped relay with an inconsequential one in the fuse box and she lit off

I think I recall reading somewhere that if the air bags go off, the fuel pump is disabled to prevent any potential engine fires. I am going to guess it takes the GM Scan Tool to reset the air bag system - and a new air bag too?
