Electrical problem
1996 Pontiac Bonneville 6 cyl Front Wheel Drive Automatic

The engine won't crank or start unless I jump the solenoid. I have checked the solenoid, the starter enable relay, the ignition switch, There is little or no voltage going to the park/neutral position switch, the fuses are good, Ihave also checked the anti-theft system, although it does have an aftermarket system as well, the resister chip in the key is working right, the security light goes off. Do you have any ideas what else could be wrong, and how to fix it?

Get a helper for this test -At the starter enable relay there's 2 yellow and 2 purple wires on the relay socket if this is correct -remove the relay and have helper hold key at cranking position-a yellow and purple wire should have power if this the case-jumper the yellow wire that has power to the purple wire that don't have power this will engage the starter -Let me know

Drop the gravel shield at the front of the engine, find your starter.(On left side near crossmember)see the big terminal?Now turn key to run position, take a long screwdriver or a remote starter tool and jump to the small terminal if the engine starts then dies its your security (vats system)it can be bypassed there are several explanations how to do this on the web"how to bypass gms vats system" fixing it properly at a dealership is very expensive. By passig the system is cheap and easy the vat system wonr work anymore but its an old car any way whos gonna steal it?
