Hi all. Thanks for stopping by.

1993 F150 5.8 efi
213,222 miles
It all started when some pesky squirrels decided to chew on my fuel injector plugin (wires coming out of head gasket) and a throttle position sensor wire. I fixed both wires but the only reason I “think” it was the fuel injector plugin was because I couldn’t find a confirmed diagram. Prior to the squirrels having a buffet of wires, I noticed the truck had somewhat of a difficult time going up hills and would only climb if I didn’t mash down on the accelerator. Otherwise, no issues as in it ran decently on flat ground.
Steps Taken:
1 - Once I had time to mend the wires, I put everything back together (with new gaskets) and all I could get is cranking with not start. Double checked all my vacuum lines, connectors, etc…..no improvement.
2 - Ran diagnostic codes: 121, 112, 512
3 - Searched around google and decided to change out the following: starter solenoid, throttle position sensor, idle air control valve.
4 – Decided to try with spraying starter fluid. Cranked (AND FINALLY) turned over. BUT it was revving really high with no “calming”.
5 – Decided to start from scratch. Retraced all previous steps and put everything back together. Nothing.
6 – Noticed my negative battery cable/terminal was loose and frail, replaced. Nothing.

What ya got? Starter motor? Ignition switch?
