apannone I just replaced my pump assembly. I was having a similar issue with long, hard starts when cold. The reason for my lost pressure was a bad check valve in the fuel pressure regulator, which sits on top of the pump assembly. The check valve is what holds your pressure when you shut the engine down or, in our case, wasn't holding pressure and allowing the fuel to return to the tank. You could just replace the regulator ($70 on RockAuto) and it should correct the pressure issue. I decided that while I had the tank down I might as well change the entire assembly, and it now runs better than ever and starts up the first time, every time.

PStov98TJ Did you replace the fuel pump reservoir as well? I have the same problem of needing to crank twice essentially every time, and after a little research I found that people suggesting the fpr as the culprit. I haven't changed mine yet, however, I plan on doing it eventually.

No, I had a short in the wiring harness going back to the fuel module. I replaced the pump before I figured it out.

s14sh3r I didn't buy a complete module for mine, but I did go with the OE pump: Bosch. The pump itself was around 70 bucks from Advance Auto and the strainer was around 15, IIRC. I didn't replace the fuel pressure regulator, but it runs from around 80 - 130 depending on brand. I wouldn't put a cheap pump in, unless you want to take a chance of having to swap it out fairly soon.

sflip09 Actually I just found a fuel pump module rebuild kit for Wrangler OEM fuel pumps. It's made by AC Delco part #19237645 for $40. It might be worth a try considering how much a new pump module cost.

toolmantim honestly your probably not going to find a rebuild kit.

Most people don't even change their own oil.....and if your going to rebuild a electrical device that is submerged in gasoline you better know what your doing.

no market for a kit.

JimsJeep Considering that it is a complete PITA to pull the pump package I don't know that I would go there without replacing the entire unit. Kinda like people pulling a trans just to change out the throw out bearing.

tightlines I am having the same issue with my 97 TJ 4.0. I hope you get some answers 'cause I could use the advice.

Fuel pump rebuild kit

Does anybody know if there is a fuel pump rebuild or repair kit available for a 97 2.5? Every time I shut my engine off the fuel is returning back to the tank and is losing prime. I have to imagine an expensive fuel pump isn't the only solution.
