EDIS stands for Electronic Distributorless Ignition System. It replaces the DIS system. ... I do know that starting in 96, Ford began incorporating this function into the ECU in some models.



My 'Tour is a 95, mfg in late 94, so I'm not sure if "EDIS" is applicable, although there must be a similar system performing that function for engine control.

The EDIS uses engine speed and crank angles to calculate timing info. The PIP signal is sent to the ECU...



I'm presuming that that the inputs to this system come from the TPS, Crank PS & Cam PS, so Ill check those out. I have a DMM for the crank & cam PS's. Gotta' see if I have an old analog multimeter for the TPS.

Any thought on the fuel delivery stuff I mentioned B4?

BTW, thanks for all your help!! I've been a hobbyist/"dealing with" cars AND electronics/electrical for 35 + years so this stuff isn't "Greek" to me, but god, can they make it any tougher for the DIY'er!!

"Hobbyist": Doing it when you want to. = FUN
"Dealing with": Doing it when you have to! = PIA!


Former, now returned CEG'er! 95SE MTX, (AKA "The Road Rat"). Stock except for:TH fix, B.A.T. big brake kit, tranny cocktail and lots of re-insulated wiring! May yet be a 3.0! "Speed doesn't kill, stupidity does!"
