If you have confirmed all that, then everything is pointing to a bad PCM but you would need to verify all power and ground inputs to it first and also the integrity of the injector trigger wires from the PCM to the injectors.

I assume you have confirmed that you have no security lights on either.

NO security lights. Here is the story, vehicle was running with the keys locked inside, door was opened by a tow truck operator with a slim jim and vehicle was shut off. Since that day the vehicle has not started and ran on it's own. That was 3 years ago, fuel lines were cleaned to remove any chance of varnish in lines and injectors. Mice chipmonks whatever got into vehicle and chewed thru wires, all the wires were checked and repaired in a proper fashion. It will run perfectly by spraying fuel into the intake manifold, it will run and come up to temp as long as you spray fuel in that way. Everything else in the vehicle will power up and work the way it is supposed to do as well. Thank for your help, I know how hard it is to diagnose a problem long distance like this. I have been beating my head against the wall on it and I have been turning wrenches since I was 13, I am now 56. I am just not seeing the problem and am looking for a fresh set of eyes or a differant perspective on this if you understand what I am saying.

The green with purple trace wire in the left kick panel was hooked to ground. That I was told would bypass the alarm system.

The pcm is on the passenger side of the vehicle correct?

You may be able to manipulate the perimeter alarm system but the PATS immobilizer cannot be bypassed and it's job is to shut off the injectors. You're going to need a factory scan tool to diagnose that.

The purple wire you grounded bypasses the door switches but that has nothing to do with the PATS system if that has been activated.

The PCM passes through the firewall. The wiring is on the engine side.

Yes, I understand the pcm is inside the vehicle and the wiring is in the engine compartment. But on the passenger side or driverside? I hate Mercury's, they have to hide crap that the Ford models don't do. Just like the Olds Bravada and the Chevy Blazer, basicly the same vehicle but differant.

It's about in the middle, a little toward the passenger side. If you open the hood you will see a very obvious large bundle of wires going into it.

Okay, well thanks for your help thus far and I will let you know how we make out with this thing good bad or otherwise. I really appreciate all your help. Fresh Ideas always help on one when you can't see the trees for the forest if you know what I mean. Have a great weekend what is left of it.
