As I said in your last question, there are very few reasons you need to go near it. A good auto electrician with a professional grade scan tool computer can diagnose the ECM for faults in about 20 to 30 minutes. It is not a job for 'let's try changing this'. If it is bad, a new one needs a tech to install as it has to be programmed with the VIN Number and mileage and set up.

Bad ignition switch,
Bad neutral safety switch
Bad starter relay.
Bad starter.

If you understand how relays work, you can remove the relay in the car and jump the switch pins together. If the starter motor turns the engine, you problem is the first 3. If not, its the starter itself.

SOUNDS LIKE A BAD RELAY

98 grand cherokee limited 5.2L same problem found leak not from heater box but from drain mount on firewall under the glove box not behind it. drain line should be located behind right front tire in the frame. Turn your wheels hard left look inside fender well right side towards back side. hole in frame where drain line should come out.

on the 2000 jeep cherokee fuse diagram was not included. makeing it hard in case of a short curcuit. fuse # 11 is a 20 amp. for the fuel pump relay. 97 to 2001 jeep cherokees. hope this helps !

Battery may be run down. Check the voltage at the battery or have the battery charged and tested.

located on passenger side below heater box toward the bottom of the firewall. going to be about a 1/2 tube sticking out about 1 to 2 inches.

The click you hear is the fuel pump relay. It gets its signal to energize from the PCM.If you have a faulty Crankshaft Position Sensor, the PCM will not work. Check for a bad fuel pump relay and also all of the other sensors: Camshaft Position Sensor, MAP Sensor, Idle air Control, Intake Air Sensor,etc.

Check fuses 5 and 8. replace both with 15 amp mini fuses, this should work for you. worked for me!!

Check to determine actual volts in battery charge if necessary. Remove & clean battery posts and inside of terminals. Check engine ends of battery wires as well making sure they are clean and tight.
