There should only be power to fuel pump fuse while the key is first turned to the run position plus cranking and while the engine is running. You can try the relearning again but if the security light isnt on when first turning the key to the run position then there is no way to do the relearn. See if you have spark a nice blue spark?

There is power to the fuse with the key in the off position. The last time I turned the key to the on position there was no security light. The light does go on at first turn of the key along with all the other indicator lights, then turns off in a few seconds. Checked for spark. Nothing.
I did get another bcm from a car that was a year newer, a 2002, should I try that? Does pulling the bcm give me another shot at relearning the computer?

I guess I'm stalled at this point, it's 11: 30PM here and I'm sure you're finished for the day. I will be away tomorrow and unable to continue until I return home on Saturday. Don't know if you're available on the weekend, but please message anything you think I should try next. Thanks for your help, will message you when able.

I dont know why you got the 2002 bcm like I said before has be the same year and engine to work. Unplugging the bcm will not give you another shot at relearning the pass lock sensor. How did you check for spark?Did you pop up coil cassette and have it plugged in with spark plugs in it touching the head while cranking the engine looking for spark?Also with the key in the run postion see if you have a 2 ohm or less to ground on the black wire to the ignition module and see if you have battery voltage to the pink wire to the ignition wire?

I'm still stumped, tried everything you suggested several times. Must be you're out for the Holiday? RSVP with any ideas when you are able.

Please answer the questions I asked right above your last post?

I did answer it several post back, but to rehash, I got both the 2001 and a 2002 just because it was there and I figured what the heck. I only installed the 2001. There is 12V on one side of the pump fuse even with the key off. I have 12v on the pink wire and under 2 ohm on the blact to the ignition module.
I also jumped between number 87 and 30 on the relay and the pump goes on.

I'm wondering if the security feature is my problem now? Is there any way to relearn the BCM after having done it before?

Tuesday morning 11AM Eastern, still no progress on getting the car to start. Any hope for me to get this sorted out myself? It's looking like I'll either be towing it to GM or to the junk yard, and taking it to the dealer is likely to cost more than what the car is worth. Anything else I can try?

Heres the tough part you dont have a scan tool when can read live data on the engine and body control module. That way we can see how both those computers are working plus see what the data values are. Also its strange that you dont have power to both sides of the fuel pump fuse while cranking. Did you try swapping the relay with another one?Also try testing the crank shaft position sensor with a ohms meter its on the block facing the radiator. See what the ohms reading is?
