Engine not shutting off! Help please!

[pontiacguy]

Here's a strange one. When I turn the key off the engine continues to run for up to a minute before it cuts off. I've isolated it to coil power remaining on. I've replaced the ignition switch, unplugged the alternator plug (to eliminate possible feedback power) and even totally unhooked the ignition switch while it's happening. I imagine that there is a module or relay in this power circuit but I've looked in Haynes and Chilton manuals and the wiring diagrams only go back to the fuse, not to where the power is switched. Can anyone help me out with a diagram that shows this? Thanks

I believe it is the same as a 95, check out this thread, http://www.lincolnvscadillac.com/forum/showthread.php?95744, I don't think you have the same problem, but that red wire they have wired to battery, if it has 12v, then the car can continue running. I posted wiring diagrams that should be the same to that thread as well.

I got it figured out guys. This car came to me like this but somebody put a BMW relay in for the high speed relay. All the numbers for the connections are the same but the terminals are in different positions. This was making the fuel pump stay on and I guess feeding back power to the coils. I don't even know why the damn thing was EVER
cutting off but it's fixed now. I do have to say that I'm really impressed with how fast it is! Thanks for the help.
