Yes please do, because I missed how a collection of unattributed quotes presented as plain text in your post validated your claim.
But hey, welcome to the forum. 10 posts in, you're doing great.
Thanks for the welcome. I'll be at 20 soon enough thanks to you.
I thought that one would understand that my entries were quotes from this forum, my mistake. The source of the quotes is this forum and I decided not to add the individual names. They are easy enough to search and verify.
Nevertheless, some individuals have had recommended the other company ("............") and my statement is validated.
Im sending out my pcm tomorrow to get it checked so no real trouble shooting for a few days ill check harness more over the weekend . yea i think with starting fluid it should have at least tried to start with those numbers
@Wranglerfix thanks for testing my computer and the amazing customer service glad we can rule that out now we know that's not the issue. Not sure where this leaves me looking now
I forget if I’ve already said it, but there are ALWAYS wiring problems. I’m a big fan of removing the harness and inspecting, repairing, and re-taping/looming the whole thing. I’ve solved several “inexplicable no-start” problems simply by fixing wiring. 100% it is what I would do next.
That said, in the how-to section I posted a guide on how to test the cam sensor, which prompted a follow up about how some cam/crank sensors are just slightly out of spec, enough to cause a problem. It’s worth a read. I’m on my phone, or else I’d give you a link. I have no idea if that’s your problem but I feel like you’ve exhausted all the usual suspects.

Thanks i will check that out today. I havent pulled the harness but i have kinda looked over it how big of a pain is it to remove
It’s really not that bad. Disconnect from the rear drivers side taillights & fuel pump, then the connectors at the T-case & trans, & o2 sensors. You can disconnect more if you need, but *my experience* has been that you can pull the harness up into the engine bay w/o disconnecting/removing the rest of it, and inspect from there.
The tape & loom are 20 yrs old and would probably benefit from being replaced anyway.
Do you know the procedure for setting up a new odpa ... i went out and moved this one around some and it was the 1st time it kind of puttered like it was thinking about starting, Its been off i think from the start even in prev posts in here i had. I dont know what the prev owner did so i ordered a new one heard the oem ones have issues so im ok with replacing it . I want to just set it up new and not base anything on the position of this one is that possible ?
So after testing and tracing every wire on the jeep with NO change at all pulled 02 sensor and cranked it and jeep started the cats are so clogged it wont run. pulling them off tonight to clean then out and reinstall. Never have i had exhaust so bad it wont start
