I have fords wire diagram at home the 4cyl is wired different,as 3.8 is also another.
The 4cyl has 2 fuseable links,1 fuel pump relay.1ecm relay.
WTF does all that stuff mean??? lol...I've never been able to understand stuff like that.
When my black car was still the running 4cyl it used to be it had a relay under the drivers seat, right on that cross bar. I left it there when I swapped the V8 in it. I used a 1992 engine harness, computer, and headlight harness. I had two relay my the MAF. I swear I also had one tied into the harness above the ECM in the kick panel. It's been two years, so that's the only one I'm not 100% on, but I'm 90%. All the wires on the selenoid together correctly? Did you have the carpet and seats out?....Do you think something stupid happened, such as the relay falling under the carpet or anything?
Dude, I would bet a buck fiddy that the puter is bad. Sounds just like my 89GT did. It wouldnt start and after testing I foun no power at the pump. I ran a wire, got it fired and it would run for a couple seconds @ 600-800 rpm then sputter and die. Took the day to figure it out. My ECU went bad from moisture as I had a small rust hole in the door jamb right abouve the computer
Open up the ECU and see if you have any signs of moisture in it. Also find a buddy with another Stang and borrow his puter to see what happens
You DID check the inertia switch, right?
Oh, and here's a simplified diagram of the engine harness where the fp relay should be..
That relay does not exist on my engine harness. only the WOT relay. Which means there should be one under the seat, i did not see it unless its hidden under the carpet. My car was unmolested when i got it, so i can be almost positive that the driver seat has never been removed. That leads me to believe that my car is either different the most 91's or the friggen title has a misprint on the year and its really a 1990
There is only one plug instead of the 2? Are you sure you got the right engine harness?
That relay mounts to the front cross bar where the front seats get bolted to. There is a hole in the carpet. The wire comes up through the carpet under the seat and has a plastic clip that pushes into the metal floor (through the carpet) Pulling the seat out and the left sill plate will help you life the carpet up just to see if it got tucked away.
Man, this pisses me off, and it's not even my car.
I really hope you get it running. I don't have any 92-93 harnesses, hell, I don't have any year harnesses. IF I did, you know I'd ship one to you to try, for the hell of it.
Sorry. Got my years mixed up. It should be under the seat. Have you checked the inertia switch in the rear panel to make sure it's good and also not popped?
