    yes, i replaced the fuel pump relay in the relay box under the hood. I pulled the grey plug off of the computer board and grounded pin # 19 and the fuel pump cuts on. That tells me the wiring to the pump is good, but for some reason the computer board is not letting the circuit complete, i replaced the computer board too and still the fuel pump will not run.

Why can't I hear the fuel pump?


on many cars , you need to crank it.
some have the prime key on for 3 seconds.
on jeeps.
check fuses first
check the ASD relay, if it dont energize the pump relay will be dead.
ASD >>> Fuelpump relay.

on jeeps, the ASD drops after 3 seconds, if the PCM sees errors.

1993 jeep cherokee won't start


MAKE SURE DISTRIBUTOR CAP ,ROTOR, SPARKPLUGS AND WIRES, OKAY IF ALL HAS BEEN REPLACED.IF NOT GETTING SPARK PROBLEM COULD BE IGNITION COIL FAULTY, ASD RELAY FAULTY,DISTRIBUTOR WITH CAMSHAFT SENSOR FAULTY OR YOU HAVE FAULTY PCM. CODE SCAN VECHICLE FOR FAULT CODE, IF YOU ARE GETTING SPARK PROBLEM IN THE FUEL SYSTEM, CHECK FUEL PUMP RELAY AND FUSE MAKE SURE FUEL FILTER BEEN CHANGED AND FUEL PRESSURE IS 39 - 41 PSI. CHECK FOR FUEL SPARK SEE WHAT GOING ON, VECHICLE NEEDS FUEL OR SPARK TO RUN IF ONE NOT WORKING ENGINE WILL NOT START.

It may be the ASD relay (auto shut down relay). They are not expensive, and I would replace it and see if this is the issue. It seems you have covered everything else as far as part replacement, at this point, the ASD relay is most likely the issue. Unless there are DTC's stored in the PCM?

How do you know what you're hearing is the fuel pump? I'd say it was weak or failing, it's what happens. Have the pump and filter replaced, it's not that expensive and an OEM pump from ebay will last a LONG time.

Where is the location of the fuel pump reset switch on a 1996 Jeep Cherokee Sport?


You don't have one on there. Pump is turned on and off by the automatic shutdown relay and the pump relay. The crank sensor signal keeps it on. If the asd relay does not get a signal from the computer (from the crank sensor), it turns off the pump relay (and spark).
The pump should run when you first turn the key on. When you start the engine, if the computer gets no signal from the crank sensor it will shut the engine off (no fuel, no spark = off)
If when you first turn the key to on, you can't hear the pump, likely either the pump has failed (check power at the pump harness) or the relay is bad.(swap relay for a known good one and try it).

check the power-wire to the pump and also the ground, replace the wire's if need be, sounds like its not getting power,make shure there is power from the fuse box were the fuse plugs in, could be a jumper-link inside the engine compartment from the regulator . good luck

No spark and no gas now what


Hi,

If you have no spark and no fuel pump operation,I would strongly suspect the Auto Shut Down relay.
The Auto Shut Down (ASD) Relay supplies power to the ignition coil, fuel injector, electric fuel pump, and the oxygen sensor heater element as long as the key is in the START or RUN position and the Single Module Engine Controller (SMEC) is receiving a reference signal from the distributor.
If the SMEC receives no distributor reference signal for two seconds or more the SMEC interrupts power to the ignition coil, fuel injectors, electric fuel pump, and the oxygen sensor heater element by removing the ASD relay ground.

Thanks for contacting Fixya.
