Long post warning, hopefully someone can help! TIA
Flash back to earlier today. I am out at a local mountainous area where I go to test new Jeep modifications. Yesterday I made suspension changes and wanted to see if I had any clearance issues. While out there, the CEL came on. Drove to the local O'Reilly's. The scanner pulled P0443 code. 2 likely issues were the evap canister purge valve, and gas cap. Initially I ruled out the gas cap, and purchased the purge valve and went home. Installed it and disconnected the battery for 1 hr. Reconnected the battery, and started it, CEL is off. Took the family for a drive and it came back on. Back to O'Reilly's I went and purchased a gas cap. Installed the gas cap, disconnected the battery again. While waiting for the computer to reset I checked the evap lines and connectors for cracks. Connected the battery again and CEL stayed off until the 2nd time I started it, and it came on again.
Pulled the #11 fuse in the glove box, and it was blown. Put another 10 amp fuse in, with the new solenoid in, and it immediately blew it and turned the CEL back on. Put the original solenoid back in, put in a brand new fuse, started it and blew another fuse.
Checked schematics, and found that the circuit for the #11 fuse is for the Auto Trans torque converter solenoid, AC compressor, and the Evap purge valve. The Jeep has no AC, and has a manual. I checked the fuse block under the hood, and do not see relays in those slots. I've narrowed it down to electrical, but electrical is my weakness.
What is the likelihood that I bought a faulty purge valve? What can be done to check the Jeep's wiring? Did the TJ's all have the same harnesses regardless of factory options? Is it possible that the circuits for the AC or torque converter are shorted?
Any help is appreciated.
