I was pulling wiring out of my firebird trying to lose weight from things I didnt need (speakers, amp, hu, etc...) but apparently I must've gotten a couple wires I did need.

At first the car would not crank over at all, then I found the correct wire to get it to turn over and connected it back up.

Now the car will turn over and run for a second and then die.

I'm thinking that it is completing the circuit when it is in the start position, but then when it goes back to the normally running position it needs to make contact with something new...and that wire must be cut somewhere.

Where do I need to look for this?

Thanks
