Not starting

[mancheflo]

So just got off work and going to auto zone to get a gift card for my father in law and as I pull into the spot the Jeep just turns off, it’ll try to turn over all lights on and battery is good, any ideas? I’ve never had any problems with it starting in the past even when it’s been below 20 Merry Christmas to me 🙃

My CPS started to give me a warning glitch before it went out completely. Just died and wouldn’t start - just turned over. After I fixed it, it seemed like it failed again; just cranked over. Gauge said battery was good, but I took it to advanced auto and had it tested. Turns out that battery had a bad cell in it. I hope something in here will help

Had the battery tested while I was there, he also tested some other stuff and said it was getting no spark so idk

Does it crank, just not fire?

 

Is it getting fuel?

Do you hear the pump priming when you turn the key?

You're at Auto Zone.  Get a fuel pressure gauge and test FP.

 

Fuel filter clogged?  How old is it?

 

Test the CPS with a multi meter.  See Cruiser's Tip on testing the CPS.  (I know Cruiser's Tip are Renix oriented, but the CPS testing is universal.)

Unplug the cps for a few seconds and plug it back in and see if it starts 

[Warren Mohler]

unplug and replug CPS a lot of times this will work if it's weak

As others have already noted, the most likely suspect is the CPS.

Loose starter motor.

Any thoughts as to if this could be a fuel pump issue? Ran for about a month or so then do the same thing and now nothing
