If your jeep has evic (overhead console). It may tell you. Justanswer suggests a maintenance interval needs reset. I have never had either of mine do this, so i am just spit-balling
If your pump is not leaking all over the jeep, you may be drawing air in the return line, or have a leaky rack and pinion. Hard to tell on the R/P unless you peel an inner boot back. Got a lot of fluid behind the boot? That is likely it.
Don’t forget to consider the ign switch actuator / broken pin scenario.
In a nutshell - key on, lites on, no crank, but you can jump the asd and get a successful start, the broken pin is a likely suspect. The broken pin does not allow the key to turn the switch all the way to start position...
I did not think the direction of flow would matter. Is there a check valve involved somewhere?
Also - I never had much faith in the ‘in rad’ coolers. They seem woefully undersized on the last one I saw when dinosaurs walked the earth and a guy could go to a radiator shoppe to get a repair...
Wiring, internal damage, bad lifter (lash adjuster) Bad rocker. Based on your trace, I am going with wiring.
These things are older than dirt and the wiring is always suspect IMO. Those little connectors on the coil is where I would start. There is a thing called a ‘noid’ lamp that plugs...

Good find Lauren!

I was pressed for time when I did my last one, and did not have the o-ring seal. Found a close match in a kit of o-rings that I bought at harbor freight. Back up and running.
Yeah, I figured you got the pre-bent. Did that on my Silverado - and some are a real booger to get there.
The line is not just copper, it is a Nickel and Copper Alloy. Reqular soft copper would blow out at the fittings wiht brake system pressures. Son and I are using the NiCopp on an old...
I dont know if Napa has everything, but I was able to source some jeep connectors as a special order from them in the Belkin parts line. 2 for my chevy cruze and a jeep bit.
every 3.7 he owned (2) had issues. Hmm.
Mine have other issues as we all have.
I recall when i bought my 04 and thought there were engine issues. I could not rev up and was then unaware of the over rev limiter (governor).
I love these little beasties!
