1993 Ford Aerostar Repair Question
93 Ford Aerostar Starting Problem? HELP!?!
I forgot to be more specific about the starting itself. The van cranks over just fine. Battery and alternator are in good condition. To me it seems like a fuel problem, but I could be totally wrong. I hope you can help me.
I have experienced these same symptoms with my 89 Aerostar, 3.0L. My problem ended up being a corroded connection on one of the joints in the wiring harness that runs between the ECM and the two multi wire connectors (about 20 wires each) on the fire wall. The joints in question are encased in wrapping and are at either end of a fusible link in the circuit. Not sure which circuit it was part of but I stumbled across it one time when I was 'flexing' that part of the harness, I could hear my fuel pump relay opening and closing. I wired in a new fusible link and have not had the problem since.
Hope this helps........

Figured out the problem. It ended up being the ECT sensor. Replaced it and it starts like a charm. But now she has a more serious problem. Transmission shifts back in forth from 4th gear to Overdrive while cruising down the highway at any speed. I told her to junk it. This van is cobbled together. The guy they got it from really ripped them off. Thanks for your input though.
