Working on a 95 ford taurus and has been stalling but is intermittent. I checked codes and I got code 114 and 543 they came back shorty after being erased.
Can you get me wiring for ECA, wire between batt and FP, I need to check for opens.
thanks

Here is the charging circuit and should give you what you need. Check the fusible links for being bad.

I'm sending what we have, check the inertia switch for hte fuelpump and check fp pressure, if it's low it's probably the pump. The second one will show the color of wires to check.

Working with the car some more and it does not start up right now. The fuel pump is not coming on, and I checked power at "constant control relay" and there was NONE on blk/org, there are 4 wires that are blk/org, what are they all?

Look at the first diagram I sent you, it goes to one of the fusiblelinks that connects to a blk/orange wire. Also if you look at the second diagram it shows the blk/orangewires leading to the 50 amp fuse in the underhood fuse box. They are larger fuses. And can go bad. The other leads go to the cooling fan.

I can't copy what you need as it's to long you are better off getting the manual here ofr 3 days and I think it's about $15 then you can print what you need off of it. There are some ground checks and such that you need to do for the pcm connector. Sorry
