Need some thoughts here. Las weekend my 05 3.7L would not crank (would not even hear that starter engage, but could hear the relay). I installed a new battery since I was still running the OEM. It was fine all week until this morning. I also installed a new ignition switch about 6 months due the common problem with flickering dash and HVAC controls. Any suggestions on next steps in the diagnotics?
Over the weekend I cleaned the connections on the starter and used die-electric grease. I had also read in another thread the potential issue with the smaller wire terminal (yellow wire that activates the solenoid). As mentionned in the other thread the terminal for the yellow wire is not sealed and the corrosion at the crimp sometimes causes issues. I cut it off and install a new terminal and used shrink tubing to seal it. Installed with lots of die-electric grease. Seems to be working great. Time will tell and I will update in a about week.
Well, I fell victim to the no crank, no start problem today. Had it towed to the garage an told them to check the wiring before they start replacing parts. They said they would call tomorrow and give me the verdict. Let's see what the say.
2005 Jeep Grand Cherokee Larado 4.7L
You can add me to the list of Jeep owners afflicted by this problem. This morning was the third time my 08 GC failed to start since I first encountered the problem this past winter. Crawling under the Jeep and wiggling the solenoid wire temporarily solves the problem - but that's never convenient. I guess I'll have to replace the connector this weekend. Jeep should release a TSB to fix this design flaw.
I just joined your club... 2010 WK.. will not start.. disconnected the + term and it worked fine for a few trys then same issue.. very flakey and intermintant.. Looks like I will be on my back fixing this problem..
