Gm antitheft problem....... Sometimes the starter clicks but fuel is not injected. Fuel comes out the fuel line when the starter doesn't click. Trying to relearn the key makes the starter click then the battery dies again.

I don't have a lot of money I know I have a good car everything works........ Heres my plan1. Try the relearn process again at 12-15 minute intervals in. The on position each time before turning it off and trying again after 30 seconds2. Try cleaning the contacts in the ignition lock or switch3. Try taking out the aftermarket immobilizer and see if that changes anything4. Try hooking up a cheap scan tool and see if that will tell me the problem5. Have it towed to the gm dealership for their diagnosis and see if I can fix it with that info6. Just pay the dealership for the f#$*@"! Relearn
if anyone else has any better ideas or is able to offer their insight please go ahead, trying to make it to toronto to visit for christmas
