    Can the one way check valve in the fuel pump assemble be replaced or not?

    I have 2001 4.0. Long crank issue. I check my fuel pressure at the fuel rail. Cranks up to 47 psi. As soon as I turn the engine off, it drops to almost 0. From what I have researched, pretty sure it is the one way check valve in the fuel pump assembly. Some say the check valve in on top of the...

    Fuel Pump Problems

    Hello! I was having issues with my fuel pump priming. PO replaced OEM fuel pump with something crappy. So I got an OEM fuel pump from Dead Jeep and put a new filter on it. I did buy a new regulator, but didn't install because Dead Jeep tested this pump and it's all working fine according to...

    88psi Fuel Pressure & Hot Start Issues

    Good evening all. I've been lurking here a bit and decided to ask some of the pros on here what the heck is wrong with this thing. No codes except a few previous from 02 sensor, evap, crank pos sensor, but those codes disappeared awhile ago and never came back. Startup cold flawless. Runs...

    Fuel Pump Connector

    I just replaced my fuel pump, on my 1997 Jeep Wrangler Sport with a inline six, and when I was reconnecting the fuel pump to the connector on the Jeep the red locking clip does not work. I messed with it for awhile and can get it to slide when its not connect but doesn't slide to lock the two...

    Sanity check before I drop some money

    In December I experienced a flashing check engine light while driving. I replaced all 4 O2 sensors and those seemed to smooth everything out. That thread: https://wranglertjforum.com/threads/check-engine-light-flashed-while-driving.67087/ Since then I've experienced two instances of hesitation...

    Solved: Jeep died on me tonight, now won't start

    Quick bit of background before I describe my problem. I bought a 99 Sport 4.0 automatic in September with 190k miles. The car died on me on the way home from the purchase, turned out to be the fuel pump which my mechanic replaced and she's been running fine for last couple months of ownership...

    Stalled after getting gas. Cranks but won't start.

    About a week ago at the gas station, I got back in and had no power at all when I put the key in. I 'tightened' the connections to the battery (which were not loose) and it started right up. Yesterday I got gas and drove about a mile and it stalled as I slowed down for the red light. Wouldn't...

    Replacement fuel pump too long?

    I’m in the middle of replacing the fuel pump in my 2004. Ordered the Delphi DE FG1221. Upon unboxing the new pump, it’s physically about 2 inches longer than my oem pump. Test fit in the fuel tank has it bottoming out and sticking out the top of the tank. Am I missing something? I’ve triple...

    No start, use starter fluid, then runs fine?

    Hi, new member. First post. I recently purchased a 1998 TJ 4.0 with 53,000 miles on it. It runs phenomenally well but won't start without starter fluid. I checked the fuel pressure at the rail and I'm getting 0psi. The fuel pump fuse and relay are good. After starting with starting fluid...

    Fuel Pump issue

    Hey all, just got done doing some trouble shooting for a code i was getting. Tested my fuel pressure and it drops slowly to 0 after pressurizing. Holds steady at 43 PSI while idling but that is still too low. Long story short, looking for a direct link or parts number for the Bosch OE fuel...

    Fuel Pump or CPS Issue?

    After working on upgrading some suspension components all last week I took the TJ (2005 X model with 6M 143k miles) for a test drive yesterday and everything was great. Tried to start it a couple hours later and it turns over freely but doesn't start, there is no sputtering or anything...

    I have a 2000 TJ Wrangler Sport with the 4.0 and a little over 158K miles on it. Since I got it I’m getting indications of a leaking or cracked seal around the fuel sending unit; I get a strong smell of gasoline any time I fill the tank more than 3/4 full, and a look with a black light...

    Jeep not starting something to do with fuel pump might be PCM

If you recall i was also the one that had the PCM willed with oil. I washed it with alcohol and let it dry for a few days. and...
