2004 Jeep Grand Cherokee won't start :(

Hi everyone,

We have a 2004 Jeep Grand Cherokee that is setting in our driveway right now because we can not get it to start. We have changed the fuel pump, fuel filter, all the filters in the tank, throttle position sensor, crankshaft position sensor. We have checked the battery, everything is fine.

My dad said that he can't get gas from the main line to the injectors. We can't tell if the fuel pump is getting any power.

This summer it started hesitating while you were driving. Not every time that you drove it, probably every 30 to 40 miles and then it would run fine. It would also blow black smoke. Took it to the repair shop couldn't find anything wrong with it. So we brought it home and changed the spark plugs. The car ran like a dream for a couple more months.

A week before Christmas it started stalling while we were driving it, blowing the black smoke again, and jumping like it was gas starved. We took it to autozone and they hooked it up to the diagnostic. It showed that it was the throttle position sensor. We bought that and changed it. It ran great for a day or so. Then it started the same thing all over again. We took it back to autozone and they still said it was the throttle position sensor. So we took it back off and took it back to autozone and they gave us another one. Installed the new one, ran fine. My dad took it out for a test drive, he got about 9 miles from the house and it started it again. He got it halfway home and it completely stopped. He couldn't get it started again, had to have it towed. That is when we started changing everything that we could think of.

Please help!!!! We have no idea what else to try. It is a 2004 Jeep Grand Cherokee with a 4.0L engine.

This sounds like need for an OEM TPS first, then (if still happening) you might do a search for the PCM connector problem that's been described in previous threads.

The PCM issue has to do with poor or marginally stable connections at the plug at the PCM and some internal contacts that just need to be freshened and repaired.

Get an OEM Fuel filter the Autozone fuel filter does not have the fuel regulator. Try getting the dealer fuel pump and install it.
