NC Tom Posted June 28, 2021 Posted June 28, 2021 I started 1-5 of @crusier54 ground refreshing and now the b*tch won't start? WTH? I have no dip stick stud with grounds. Previous owner(s) moved them to the neg batt cable location. I removed and cleaned two round connectors and the neg batt cable and the stud. Put them back. I removed and cleaned the braided cable attached to the firewall, but not the end connected to the engine. I could not budge it. That's as far as I got. Truck turns, catches and immediately dies. This is my DD, so I need help ASAP. Also found some mystery connectors. One of them a Ford?! I guess should have left it alone. No good deed goes unpunished.
fiatslug87 Posted June 28, 2021 Posted June 28, 2021 Sounds like a fuel issue to me if it starts then immediately dies.
87MJTIM Posted June 28, 2021 Posted June 28, 2021 The connector near the booster is for a XJ rear window washer pump. Not applicable to the MJ. (I don't know where the other end is. )
87MJTIM Posted June 28, 2021 Posted June 28, 2021 The blue vacuum line is for the front axle CAD. (I believe.)
mjeff87 Posted June 28, 2021 Posted June 28, 2021 Bypass/jump your ballast resistor (white ceramic looking thing on inner driver fender area beside the airbox). See if that fixes it.
NC Tom Posted June 28, 2021 Author Posted June 28, 2021 Thanks for the replies. Prior to the ground refreshing, I was having an issue with the engine turning over and over and over without starting. I unplugged and replugged the CPS and all was good for the past week. After the refreshing (Friday 6/25) is when things got worse. CPS trick worked again. It sat for three days, tried to start today and no-go. So, I tried the CPS trick again and it worked. Runs good, drives good. Just tried another start and it started after sitting for several hours. However, there is a strong fuel smell, but I don't see any leaks and nothing on the ground. I know I need a new CPS, but there is something else going on. I think.

JMO413 Posted June 28, 2021 Posted June 28, 2021 Just read your signature and love it. Have you tested the CPS? Have you tested fuel pressure? I would also check the sensor ground. http://cruiser54.com/?p=47
pizzaman09 Posted June 30, 2021 Posted June 30, 2021 Prove if it's a fueling problem by trying to start it and keep it running on some starter fluid or a spray bottle of fuel into the intake.
cruiser54 Posted July 1, 2021 Posted July 1, 2021 Continue with the Tips. The C101 likely has resistance in it, lowering your CPS signal to the ECU.

It's running now as long as I don't let her sit for too long. Then I have to do the ol' CPS unplug-n-replug. Ordering a new CPS today. Crusier54 can you verify that the grounds that I addressed at the top of this thread are all that are usually connected to the dipstick stud? I your notes, you mention quite a few components being attached there. I only had two connectors.

cruiser54 Posted July 21, 2021 Posted July 21, 2021 I wouldn't be surprised if it does. How many other Tips have you completed?

cruiser54 Posted July 24, 2021 Posted July 24, 2021 To put it bluntly: You need to concentrate on completing the Tips instead of pounding the keyboard.

watchamakalit Posted July 24, 2021 Posted July 24, 2021 can't you just run it up the next mountain to slow it down?
