Fuel pump power sensing for the ECU comes off of the fuel pump relay output but before the crash/shutoff switch. The relay is in the box behind the battery. It may pay off to pull the battery and this this box to check the condition of the wiring and connections. This area is known to corrode. Fuel pressure may be present regardless of this signal, check at Schraeder fitting.




Checked the relay and its ok. The wiring under the auxilary fuse relay box is pretty bad, but I've isolated and
re-insulated the majority of the bad wiring. Like I mentioned, I have to get the wiring harness recall done. I am on my way to Pep Boys now to buy a fuel injection fuel pressure gauge as soon as I finsh this thread. (No one around here seams to have one to rent/loan.) Then I'll put the pump and pressure regulator through the tests.

MSD sells an ignition module for the Ford Contour called the DIS-4. This is an external module, so they may all be external DIS modules. The DIS and EDIS use crank position for timing both ignition and fuel injection events, but the DIS system is more dependant on the cam position sensor for establishing and maintaining correct cylinder sequence at all times.




If it is what/where I think it is, is it about a 4.5"x3"x.75" rectangle with a a 12 pin connector? Sits on passenger side firewall to right of pwr steering reservoir? Any way to test the bugger? (Probably not but figured I'd ask.)I'll have to check out the MSD website and see what I can learn there. I checked the cam and crank position sensors and both ohmed out within spec. Checked the TPS and it SEEMS ok, but I only have a digital multimeter and I know I should use an analog one for that test.

MTX. See my sig.

Thanks again.

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!"
