Question about Jeep Grand Cherokee
Have you checked the connections and current to the fuel pump?
Posted on Jan 09, 2009
I am going to assume that it will not run even if you push on the accelerator pedal?
Can you install or attach an old timing light to the spark plug wires, turn it one and try to start it. The light should flash with the engine running, but if it shuts off at time of engine die, and the engine is still spinning, you are losing spark, My suggestion is the cranks shaft sensor on bell housing.
Second, install a pressure gage on the test port on the fuel rail and watch it as you start the engine, fuel pressure should not drop as the engine dies, if it does, the pump is not working correctly. There are two modes of power to that pump, one to start and timed, for only a few seconds to prime the system, and one to run continuously. Find the wires going to the pump at the tank. Connect test light to those wires and watch what happens during crank and at stall, You should not have the pump shut off and the engine dies.
If you have spark, and fuel pump working, when did you last change the filter,,but I put that LAST.
It has to be one or the other of these.

Have you made sure the rotor is turning in the distributor, as this sound like a cambelt failure.
Sorry to bear bad tidings if this is so.
Please remember to politely rate my effort!

it is possable/likely a bad ECTS (engine coolant tep. sensor), this can cause the injectors to allow to much fuel into cylinders and cause a low compression and or flooding situation, good luck, marty
