\'86 F-150, 300 Problems

Hi Guys,

I'm new to the list and I need your help. I tried searching but no such luck.

Last night driving home, my truck died. I tried to start it but the starter doesn't turn over with no lights on the dash but headlights do work. I check for spark at the coil but nothing. I was told by someone that the problem is the TFI (ignition module) but I'm not sure if the TFI will keep it from cranking but I think it will keep it from providing power to the coil.

My questions is: Will a bad TFI keep it from turing over and also knock the lights out in the dash? Or do you think I have a bad solenoid and/or coil.

Thanks in advance!
Tom

Re: \'86 F-150, 300 Problems

I would say that you have some bad wiring and/or some blown fueses. Does the starter silinoid make a click noise or just nothing. Usally a computer or ignition module will not stop the starter unless it has an auto shut down relay. The auto shut down will stop the fuel pump, coil, and some times the starter silinoid. If the silinoid still clicks then it is not from a computer, module, or shut down relay. But seeing that you lost your dash lights and your starter it sounds like it is electrical. I dont think that a 86 ford has a auto shut down relay not until the 90's I think. A computer or ignition module will stop the fuel pump and coil but not the starter. I dont know if the trucks had them but the mustangs had some kind of a shut down if it sensed a hit and you had to pull something in the trunk but I dont think the trucks had this.
