The wiring diagram is hard to read. Can you email it to me so I can get a better look at it? mpjosh2001@yahoo.com

My voltage meter on my dash has been fluctuating. The engine has even died a couple of times from it dipping too low. I think my codes may have something to do with this. I changed my alternator and it's still doing it. My mechanic friend said it could be the gage cluster it's self. I fould that to be rather odd. This is my first project with efi, so I don't know what's going on. I'm about ready to take it to a shop and say fix it.

With all the codes you're getting the motor can't be idling smoothly and that will affect alternator output so ignore it for now, focus on figuring out what is wrong with your wiring.

I used some of the wire taps to tap into the pwrgnd wire. I think I may have severed a few too many strands with that. I'm gonna undo everything and solder it like I should've to begin with. Thanks for all the help.

spent 3 hrs going over the wiring with a ford tech and determined the PCM is fried. Engine still runs though, so I'm gonna drive it until I can scrape together the cash.

New ecm cost 150 from Napa. I recommend anyone doing this to just buy a new one instead of ordering off ebay. It'll end up being cheaper in the long run. Everything runs good now. I have great throttle response and a smoother acceleration. I do have a bit of a miss fire issue when I let off the accelerator and the reaccelerate. I think I just need to adjust the timing a little. However, I do still have a voltage drop when I go from P to D or R. Hasn't stalled like before though. Now I have a t-case issue which is a whole nother subject. I hope this will be able to help at least one person out in the future. I appreciated all the help I got from you guys.
