[QUOTE="CurtT, post: 441211, member: 21427"] no problem, ill try to give you as much as i can... 1. jeep was running fine for a very long time. had off road for couple weeks and check engine light came, had a hole in muffler so was sounding great(sarcasm). as well as my alternator was making some bad squealing noises. and check engine light came on. 2. brought back home checked with computer and said i had high voltage to TPS censor. 3. I replaced alternator because of noise/ squealing. 4. checked TPS censor (which had been replaced roughly 1 year ago) and throttle as shown on Youtube video for YJ 2.5. also took throttle body off and cleaned thoroughly because was pretty dirty.. 5. then had issue with my ECU which ended up not working so i purchased another ECU from a jeep wholesaler out of Daytona. replaced ECU and still had same issues as before. had to replace ECU because the computer fried and would not start the jeep at all. FYI wasn't just replacing to try and see if worked. 6. I've checked all the 5 grounds and removed and cleaned the contacts and also traced the 2 lines from the TPS back to ECU to make sure there was no cross over of voltage. 7. also pulled the pages off the chryslers books you supplied about TPS high voltage issue and repairs and went through everything multiple times. which after doing the test multiple time keeps saying to replace the ECU again.. this is where im at. getting frustrated but trying to figure out. dont like sending to mechanic and like trying to figure out, but wiring/voltage issues are a complete pain is ass!! hope this helps..
