Completed Tips 1 through 5 yet?

That white block is not stock....what a mess!!!

Bingo, Eagle!!

Here ya go: CRUISER'S MOSTLY RENIX TIPS IMPROVING THE FUEL PUMP GROUND JANUARY 3, 2016 CRUISER54 49 COMMENTS The fuel pump and fuel tank sending unit ground at a sheet metal screw up behind the spare tire on an XJ, and behind the driver’s taillamp on an MJ. Not only is a sheet metal screw a lousy way to ground things, this ground path is long and travels through some connectors that are prone to corrosion and moisture. Locate the black wire on the HARNESS side of the fuel pump/sender 3 wire connector. Remove a 6″ length of the split loom covering. Strip back about 1/2″ of insulation from the BLACK wire. Take your new ground wire, preferably at least 14 gauge and 12 to 18 inches long as needed, strip it about 3/4″, and wrap it around the exposed part of the harness plug wire.Solder the connection. Tape it up and reinstall the split loom covering. At the other end of your new ground wire, add a crimp on eyelet. Attach the eyelet under a bolt that goes directly into the chassis. Be sure to clean the attaching point til shiny and apply OxGard to the contact surfaces.

Renix is simple and it's quirks are well documented and easily remedied.

No matter what, you guys need to do the fuel pump ground mod. Just cuz.

ever done this? CRUISER'S MOSTLY RENIX TIPS CONNECTOR AND RELAY/RECEPTACLE REFRESHING OCTOBER 30, 2015 SALAD 22 COMMENTS I suggest unplugging EVERY electrical connection in the engine bay you can find, whether engine related or not, and spraying it out with a good electronics cleaner, visually inspecting the terminals making sure they haven’t retracted into the plastic holder, and then plugging it back together. There’s a critical 10-pin connector for the front lighting system located in front of the air cleaner and behind the left headlight assembly. Don’t miss that one. Also be sure that the connectors to the ballast resistor mounted near the air cleaner housing are clean and tight. ALL of the relays should be removed, the terminals wire-brushed until shiny, and the receptacles sprayed out with contact cleaner. Then plug them back in. I do this on every Renix Jeep I purchase or work on for someone else.

I have no idea. They went to NGKs when they needed good spark plugs for the waste spark firing of the coil rails. Ya know, when the plug fires on the exhaust stroke also?

Do the fuel pump ground mod!!! You mention humidity playing a part. How old are the plug wires? Did you look at the coil as suggested?

NGK ZFR5Ns in all 4.0s. NGK has always had the same heat range. 5.

No plug wires?????

This^^.

Will it spin 2 complete revolutions by hand? Marvel Mystery Oil, ATF, and diesel fuel mixed together work the best.

Absolutely^^.

Have you changed the fuel filter? There were some coil failures in the 90s on the HOs. see if yours is a Marelli. That's the one that failed. Test your fuel pressure with a gauge. Is the fuel pump loud? Since it is a Comanche, I would for sure do the fuel pump ground upgrade just cuz. How old are cap, rotor, plugs and wires? Have you inspected them since you got home? Oil smell like gas?

You Tube the coil tests. Are there any diaphragms in the carb that mighta gotten messed up by old fuel? Huge vacuum leak anywhere? Is the needle and seat actually SEALING?

The 304 is an absolute dog.

What are you referring to as B pillars? The trim pieces? And yes, folks need to be snatching this stuff up ASAP. Taillamp assemblies top the list. Wait a week and that one is gone forever..... A concentrated effort is our best bet, no matter what generation we're from. The Comanche's generation is long gone..... Maybe I shouldn't bother with this as I have more than I need of the rare stuff, eh?

And, I have a few good used ones along with EGR tubes.

Are you done yet?

ahem.....

Not sarcastic at all. Consolidate all the threads together. We could have a "Wanted" section, a "For Sale" section, and the "I'm gonna make them but never do " section. That way, those that want could find sellers, those that are selling could find buyers, and those who are gonna have them made could take orders.
