1999 Tahoe anti theft

[Swilly]

I need help with my 1999 4 door 4x4 Chevrolet tahoe. It sat in the yard without a battery in it for a few months. When I put a battery in it and tried to crank it the anti theft wouldn't let it. It starts for a second or 2 and immediately cuts off. A friend of mine put a jumper wire from the I believe pink and orange wires in the steering column saying it would bypass the anti theft  And it worked. Crunk up fine. No problem. Well then he touched a wire to something or another wire and it sparked. And now it won't start again.  If anyone has any information that might help me it would be appreciated

What pink and orange wires? Can you take a picture? I highly doubt it starting was anything more than coincidence. Passlock 1 and 2 require the resistance value to be matched upon ignition cycle. Simply shorting the signal return and R-code wires together will not accomplish that. Also, the passlock wires have white, black, yellow, or orange depending on year/ make/ model, but never a pink wire, so I think your buddy messed something up.

When it did start I cut it off and started it back up about 15 times. Then 2 days after it wouldn't start again.
