Blowing Fuse 11
Hello everyone first post, may be a bit long but desperate for some advice.
1997 Wrangler 2.5L Automatic
Changed the transmission, started and ran prior to changing it. 3rd transmission, first one pump busted, second one from Advance was a shawdy rebuild, so this is one they sent us from the warranty claim. Replaced the radiator and intercooler as well.
-Put everything together filled the fluids, Crank no start fault.
-Replaced the Crank Sensor just as a shot in the dark, the one on it was still new. Same fault
-Noticed the 11 fuse was blown, replaced and it blows when you turn the ignition, does not have to crank to blow it
-Tore out and ran 90% of the wiring harness, from the driver side O2 sensor, CPS over the junction on passenger side at large black connector, all the way back to the plug in the rear gas tank area, seen no clear issues, only wiring left to go through is the passenger side junctions and leading up to the computer. Also checked the wiring at the fuse block outside.
-Replaced the coil pack as a shot in the dark, same fault
-Disconnected everything from the plug to the rear harness, transfer, transmission, computer, crank sensor, even the two large(1 gray, 1 black) connectors on the firewall. Plugged them up one at a time to see when it would blow the fuse.
In order of being plugged up:
1. Computer all 3 connections - did not blow fuse
2. 2 large connectors on firewall - did not blow fuse
3. Crank positioning sensor - did not blow fuse
4. Connector on driver side of transmission, circular connector 3 prong sensor on trans - did not blow fuse
5. Connector on the back of the transmission, just above the trans pan - blowed the fuse
Any assistance or maybe something I can test or try to fix this thing would be greatly appreciated. My sons jeep, he needs to get to work and school and needs to stop driving my truck XD.
