my fuel shut off solenoid keeps catching on fire
#11
The fuel shutoff solenoid is actually two solenoids in one. One coil is very strong to pull the linkage open when you hit the starter to let fuel flow. This first coil produces lots of heat and is intended for short use. The second coil is smaller and has just enough power to hold the solenoid open for running. It does not build up heat like the stronger coil.
The stronger coil is wired in with the starter so when you hit the starter the fuel solenoid opens and the engine starts. When you let the key return to the run position only the second smaller coil is needed to hold the solenoid open.
When the worn starter contacts hang and stick closed the stronger first coil stays energized along with the starter. This causes heat buildup after a short time and can actually catch fire if the battery isn't disconnected quickly.

The small coil isn't strong enough to pull the coil in. You could do what you suggest if you want to pop your hood and manually pull the coil in by hand every time you want to start the truck. Other option would be to wire in a switch to the pull in wire, and turn it off once your trucks running. At this point, you've done almost as much work as changing the starter contacts.
