Jeep Will Not Deliver Fuel

I have a serious dilema here trying to get my car to start, I'm running in circles trying to get my 99 Jeep Grand Cherokee (V8) to Died on me in February on one of the main roads, it seemed like it was doggin a bit, and when I hit the brakes ( Bam! ) the thing dies and would not start. When I tried to restart it I could hear a bunch of clicking so I thought that I smoked the timing chain. Needles to say I've replaced a ton of stuff ( listed below )

New Timing Set
New Fuel Pump ( Which I know is good - I hotwired it w/ 12v to test and it pumps )
New Filter / Regulator
New Fuel Pump Relay

I know that the 20A fuse isn't blown, and I know that I get voltage to the connector when cranking...I verified it with a voltmeter. I also know that when I spray the intake with starting fluid it runs ( for about 3-5 seconds ), so I know I'm getting spark and that the timing is correct. I"m completely lost here...the car will not pump fuel still, I have the fuel line disconnected at the rails and when I crank the engine...nothing.

Could it be the PCM? I really don't know what else to replace...

Please Help!

Where is the fuel filter located, ona 99 jeep grand cherokee?


There are 2 filters.
  1. One is on the end of the pickup tube inside of the gas tank.
  2. The second is in-line, above the front edge of the gas tank, inboard of the frame member. It is part of the fuel regulator/filter assembly.

Here's a diagram:

Take care.

I have a 2003 Jeep Grand Cherokee that has a fuel problem, after it sets for an hour or longer, it is hard to start, it seems like that if I pump the gas peddle, while starting it, it will crank up after a...

i know on the 99 mountaineers with the 5.0 the way the fuel lines were routed from the factory, heat from the motor would vaporize the fuel in the lines when engine was cut off warm. It would turn quite a few times before starting after that happened. try turning your key on and off a couple of times before you actually try starting it and it should start quicker. I know this from experience.

I have a 99 grand cherokee iwas driving about 10

check your fuel filter it could be restricted that won't show up on test. A faulty fuel pump wont show up time it stalls check to see if you can hear the pump running when you turn the key on. (filter may be part of the regulator on top of the pump unit on top but outside the tank)
