Being as I've been troubleshooting an electric dryer tonight under pressure from my wife, and haven't found the issue yet, my brain is fried. If you're concerned about a vacuum SOURCE for the controls, any source is fine as long as it has storage capabilities like the factory one inside the passenger side front bumper.

To me, On and Run are one and the same. Resistance to battery from where?

I'm confused about the vacuum thing. Perhaps a Factory service Manual with the HVAC diagram would be useful?

You will LOVE it!!

Yeah!! We don't need no stinkin dipstick tube studs!! LOL.

Night Don. I drink nothing with a twist off cap.....

I was right? I'm a beer profiler.....

Yup.

Yep, I'm jealous. But you do see the big picture. Controversy breeds knowledge. Hell yes. I'm all over that!! I drink IPAs/microbrews and I'm guessing you're a Miller guy...Correct?

LOL. You're just jealous you don't have something as simple and efficient as a rEnix.

I probably have the same injectors as you on my 3 family Jeeps. I installed the 746s on my neighbor's 87 and they are really nice.

Hope it helps. see Tip 22 if you need the harnesses.

Oh, we've surpassed that long ago.

So, was it worth it? LOL. Put a set of 746 injectors in it if you haven't already.

I'll post it here for you then. http://comancheclub.com/topic/36382-cruisers-renix-tips/

Snip the wires then. Install new eyelets and ground everything somewhere else then. You'll be fine. Remember though where you ground it. clean and shiny like a baby's hiney.

You can hold the stud. It's got a reverse Torx on the end of it!!

Just do this and be done with it. http://comancheclub.com/topic/17377-cad-fix-1/

In my signature? Red letters?

So what about the Tips?

Sure could be. But with a loose dipstick grounding stud, all bets are off until that's addressed. The Renix era XJs and MJs were built with an under-engineered grounding system for the engine/transmission electronics. One problem in particular involves the multiple ground connection at the engine dipstick tube stud. A poor ground here can cause a multitude of driveabililty issues, wasted time, failed emission tests, and wasted money replacing components unnecessarily. The components grounding at the dipstick tube stud are: Distributor Sync Sensor, TCU main ground, TCU “Shift Point Logic”, Ignition control Module, Injectors, ECU main ground which other engine sensors ground through, Oxygen sensor, Knock Sensor, Cruise Control, and Transmission Sync signal. All extremely important stuff.

I am not computer literate enough to post photos here. click on my Tech Photos link below and scroll through.

I think I have a diagram. And now you do. Check your email.

Have you tested anything like cPS or done any of my Tips?

That loose stud could be 99% of your issues. Hold the stud still with a wrench and remove the nut.
