Customer Question

I have the harness and computer out of my old 2001 express van no longer have the van but I do have the motor and harness and computer like I said have it hooked up in my garage for bench testing however it won't fire the spark and the security light comes on after a while how do I disable the security function so I can put this motor in another vehicle and run it with the factory computer
JA: Does the light flash, blink or stay solid? Have you tried to reset the security system?
Customer: From what I see it stays on steady I don't have the key Phons just the steering column at ignition key
JA: Are you fixing your Express yourself? What have you tried so far?
Customer: I pulled the engine from the van and jump the van I want to put this engine in another vehicle
JA: Anything else you want the mechanic to know before I connect you?
Customer: Just how to get the engine to start

actually this model does not use the bcm my apologies I went over the passlock system and there is a module that relays the ignition switch signal to the passlock module, then from the module it tells the ecm that its ok to start. here is where its located.
