1991 f 250 when starting during cold weather starter sticks to the run postion and ignition i can turn back and forth and truck will not shut off until starter burns out

IT sounds to me like the solenoid is sticking. Follow the large wire up from where it bolts onto stater and the next thing that wire is bolted to is the solenoid.

Call Autozone or Oreillys and see if they show an Ignition relay for your truck. This relay would kill power to the Ignition switch.

If no relay, check the small wire or wires on the Starter Solenoid with a test light or 12 volt meter. Have a helper turn the key to Start with the small wire disconnected from the Solenoid. If no helper, Ground Neg. end of tester to vehicle and the other end to the disconnected wire and put the tester where you can see it light up or the meter move.

Then turn to Start position and see if the tester lights up or the meter move. These small wires go back to the Ignition keyswitch. If no power to the Solenoid, the wires are bad.

You can jump the Starter Solenoid with a screwdriver or Battery cables If the truck is in Park or Neutral and the Ignition is ON, the truck will start and run until you shut it off.

Double check your new Solenoid, for the right type. There are Negative and Positive ground Solenoids. There are 1 and 2 wire terminal types which is easy to see. But the Positive ground Solenoids go on Boats and are also used on Hydraulic pumps for heavy equipment.

1991 ford pickup truck

I recently had a problem with my '91 F150. It had started fine. Then, after I cleaned it some, it died and wouldn't start again. I think the ignition control module got wet on mine. If you are not getting enough fire, you might want to take the ignition control module off the side of the distributor and take it to Autozone/Advance or the like and get it tested. (You can get enough fire to turn the starter and it still not be enough. You'll need to take a plug wire off and see how hot it is when you turn it over.) The ignition control module is held in place by two screws that you can remove with a 7/32 socket if you have one small enough to fit. (Make sure they test it a few times (until it gets hot.) A bad one may test fine at first.) If it tests fine, you might want to buy a coil. For more detail about the ignition control module, see: I don't know if your starter is turning over or not. If it is not, you might need a starter or solenoid. If you jump the solenoid and the starter turns, you probably need a solenoid. If not, you probably need a new/rebuilt starter (and maybe a solenoid, too.) I hope this helps! Peace and blessings!!!

Check all wires and switch used to wire the push button ignition. Make sure none have melted due to the stress from hard starting in cold weather. If a thick enough guage of wire was not used it will get hot and could melt.

95 F150 wont crank

the starter should be replaced. The solenoid is kikcing the pinion out but there is no contact being made to turn the starter motor. I have the exact same truck and before i changed the starter used the old starter tap trick. Tap the starter casing with a hammer and it should start turning again. hope this was helpful for you. Good luck.
