Do make sure you have less than an ohm or so of resistance between that ground wire and Batt.Neg. In Cruiser's tips he points out where a bunch of grounds meet at the dipstick mount stud. His links are in my sig allong with some other random renix stufff.

you people are beyond stupid. “Cruiser” is the dumbest person on this forum. The upside to him is that all of you are dumber than dumb. You know nothing about cars or electronics, so the stupidest person alive seems like a ****ing genius to you. I’m am sick of this ignorant fools advice being passed from person to person and forum to forum. Show me one case where this ignorant fools advice helped!!! Prove me wrong. I see a lot of “it didn’t fix the problem, but I feel the difference”. STFU! You people are delusional! Cruiser is an *** clown. Everyone who thinks this dumbass knows anything is a fool! You should pay someone to fix your vehicle because obviously you are too stupid to do it yourself!

this ignorant fool “cruiser” tried to tell me a PCM does not go bad. It must be a ground issue. Guess what, it’s the ****ing PCM!!!! He also loves to say the no start issue is 99% of the time the CPS. I have had one CPS go bad. Usually it’s a fuel problem or bad ignition parts since these things are so old. This dude is simply too stupid to be offering advice to anyone. And to anyone gladly taking his poor advice and running with it like Jesus spoke to you, you deserve the punishment you receive for following a clown dressed in cloth.

****ing idiots!

rant over.

Who touched you in your no-no spot? Was it daddy, a teacher, or a priest?

GTFO with your BS. Cruiser54 has helped more people here than the genetic slime you outraced into existence...which was your biggest accomplishment BTW...

STFU and GTFO with your BS

I have been jeeping for 15 years now and specifically joined just to state that nothing could be further from the truth and Cruiser54 is one of the best sources of RENIX information out there. I disagree with him on very, very few things when it comes to RENIX info and usually it's just a matter of presentation or minutiae not actual significant facts.

Also this thread is from 2016 and it's pretty funny that this abrasive dicknugget chose to bump it to call one of the more respected members of the XJ/MJ community names just before I needed this info and found it via google rather than bothering to pull out my FSM. So thanks I guess.
