I need your help bad.

I come to you in need of help. I own a 1995 s10, 2.2, 4cyl. I swapped out engines with a 2000 2.2 4cyl, auto. My problem is, passlock is keeping me from running the truck. The truck will start up fine then die after 2-3 seconds. I have read that you can splice into the column wires (3) but my truck is a 1995 and wouldn't have those wires,Right? I do not have the 2000 BCM, All I have from the 2000 truck is the engine, tranny, comp, and harness. I have found a trick to start the vehicle. I unplug the harnesses in the comp turn the key to run. reconnect the harness and 8 out of 10 times it fires up. But once you turn it off, you then have to unplug/plug trick. Since This is my wife's only vehicle and I am to depart back to Iraq, I am loosing my mind to try get this thing running in a short time. Please if you have any info that might help or someone I might contact would be very appreciating. Thanks in advance. Sgt Sparks/USMC

Can you deactivate the Passlock System? If you don`t use the remote start feature, why do you need the Passlock?
The 1995 engine used the OBD1 on board diagnostics. The 2000 Engine uses the OBD2 system. Normally the computer will not shut down your engine- it just manages the fuel/air and stores codes.
Can you get the ECM from the vehicle the engine came from?
If you can send me the ECM part number, I will try to find the ECM number you need.
Most of this info is already on the internet.
Good luck on your next deployment.

Why not just put that other PCM from the other motor? That's the only thing I can think of unless you can get the column with ignition key that the new motor came from.
