You probably tripped the '0' oil pressure switch and it needs to be reset. Find it and reset it.Newer vehicles have switches that use inertia, oil-pressure, or Rpm's to shut off electric fuel pump in case of an accident. Find it and reset it.....

On this very forum, there is something to tell you how to reset your PCM. I would bet that's what shut off your engine due to momentary loss of oil pressure. It's easy, just unhook your battery for 8 hours and Jeep should start. PCM on jeep shuts off elec. fuel pump due to low oil pressure and needs reset by interrupting "short memory" phase by un-hooking battery for 8 hours. Just look it up, Google will send you to this forum with answers ready for you.....

His Jeep has neither of those systems/features.

Where do you come up with this stuff?

colt44

There is also a 'ceramic' relay for elec. fuel pump located in engine compartment on drivers' side. It is designed to break with an impact and is designed to only carry power for fuel pump. It is separate from relay box and fuse box, and is designed to interrupt power to fuel pump in event of a impact, like hitting a large pot hole. Ceramic material, as we all know, insulates electrical impulses with little degradation of voltage, but breaks easily and provides a safe-guard in cases of impact.

I checked the voltage to fuel pump. It is getting 12.8v at the fuel pump wire harness. So power is getting to the pump.


I'm trying to get my sending unit out. WOW!!! Im guessing there is no easy way for this to happen?

Like cruiser said, "Where do you come up with this stuff" Sounds like you are making things up as you go along. That isn't put on there for a safety feature. It is there to lower the voltage to the fuel pump.

Outlaw Star

Sorry, but that piece doesn't work that way on the Xj.

Ya know, we're here to help folks solve their issues.

We're NOT here to spread BS and untruths that could possibly waste another member's time money, and resources.

Not only do uninformed and irresponsible posts like that cause possible grief to the original posters, it wastes the time of others who have to correct the information. As you can see, RTorrez, OutlawStar and myself have been inconvenienced already. Me twice...............

Well, I hope the guy gets his Cherokee running. I thought the 'pros' on this forum would've spent more time telling OP to replace his fuel pump instead of ganging up on a opinion that went out of their comfort zone. Oh, well. At least I put research into it instead of just criticism. Everything presented by me wasn't opinion, but backed up by articles on inter-net. Unfortunately, some people can't find a site that isn't on their 'history' button.

cruiser54

You answered perfectly. He/we don't need "opinions" , especially those concocted from poor research and little knowledge of the Jeep product line.

I have a very WIDE comfort zone, but no TOLERANCE for arrogant, BS, ego inflating posts that could cause harm to unsuspecting people.

Not to mention, there would have been no criticism if YOU hadn't posted false, misleading information.

colt44

It seems to me everything I suggested cost nothing and was based on experience, not opinion. I used the word 'maybe' and 'should'. You guys are the ones telling him to go buy a volt meter and trace 25 miles of wiring. I would've read the responses and filed them away for future use, except for ham-handed insults that followed my original post.

DFlintstone

Glad you got it isolated to the pump. Actually easy is the only way! It takes a little patience/finesse. (it's all one unit). Be careful not to catch the filter screen on the lip and knock it off inside the tank!

LongLiveXJ

Well this conversation escalated quickly.
How many miles are on this thing? You may not have been long for a fuel pump anyway.

cruiser54

What experience? With Fords? Cost nothing? Wasted time chasing things that don't even exist on his vehicle?
Yep. That's sure better than tried and true solutions on JEEPS that we're familiar with.

Gimme a break.

Alright. I know most forums operate on advertising revenue, including this one, and not on supporting members. As a 'regional moderator' you were probably instructed to keep up the 'daily post count' so quarterly ad revenues would increase. You did a good job. Talk-Show hosts increase ad revenue by increasing viewership. How much do you get paid by post? I'm sure this one is about 10x more than it should've been. Good job!!
