Question about 1994 Jeep Grand Cherokee

2 Answers

94 Jeep Grand Cherokee is hard to start. If I turn the key on and wait several minutes till I hear the fuel pump kick on, then it'll start right up.I have replaced the fuel pump, fuel pressure regulator, crankshaft position sensor, automatic idle control valve, throttle position sensor, distributor cap and rotor.What else should I check?

    When I turn the key on it takes several minutes for the fuel pump to cycle. It takes longer if it's cold.

    The ignition control relay was replaced early on.

    You should hear pump cycle as soon as key is turned to on (not start) position, is this not the case?

My 1995 jeep will die just driving and sometimes will start right back up other times you have to wait about an hour. fuel pump is working fine you can hear it


The pump can be running but not pumping any fuel.
When it stops running you will need to figure out if you are loosing spark to the plugs or fuel to the injectors.

The first years of that body shape, like the 93 Grand Cherokee, had ecu computer problems. Next time it won't start, check to see if the check engine light does lights up on the dash, when you turn the ignition on, before cranking. If it does not, the fuel pump will not kick on, until that check engine light does come on. It's referred to as the delayed check engine light problem, on early to mid 90's Jeeps. If you find out that is indeed the problem, you can have the ecu computer repaired.

After it stalls, have someone listen at the tank to see if the fuel pump is running when you turn the key on. If you can't hear it, it has failed (they overheat and bind, when cooled down they work 'till they again get hot). if the pump is running, likely the crank position sensor (11 o'clock on the bellhousing looking from rear) has failed....symptom is pretty much identical.

No power to fuel pump on a 94 cherokee what could be the problem? all relays are new.


the oil pressure switch conjoins to the fuel pump feed upon starting the engine. once the engine gets to normal oil pressure the computer will shut the feed off from the oil switch and turns the relay on to take over till you shut the engine off. If the fuel pump is good try this test. Turn the key to the on position & do not start the engine. You will hear the fuel pump running if the oil switch is good

Fuel pump is bleeding back so it isn't holding pressure in the lines. So when it sits long enough it is hard to start. Try turning the key on and then off wait 15 secs or so and turn key on and then off again do this one more time and see if starts. If so then you will need to replace the fuel pump in the tank soon.
