Having problems with your 1996 Pontiac Grand Prix ?

Car will only start if shorted across to the starter, but within 5 seconds it dies and won't start again without shorting it across. Has good battery, good alternator. Checked all fuses. At a loss?? The key for the car is old and is has a chip that allows access due to security system...could this be the problem?

Yes! sound like the anti-thief system is causing all the troubles. the ignition lock cylinder has two small wire that read the chip on the key and send signal to the computer when you insert the key to the lock cylinder. because it ( the wire ) moves every time you turn the key, after a while the wires will break and cause an open in that circuit.
\015\012you need to replace the ignition lock cylinder ( you can repair the wires, but I donot recomment.)
\015\012you can either have a lock smith to rekey the lock cylinder to your original key, or you can just take the new key came with the lock then have the lock smith make a copy of the new key with a chip has the same resistor with the old one.
