I got home yesterday and shut off my jeep, when i tried to start it up 15 mins later it just turns over. I'm not getting any fuel to the injectors so i thought it was the pump for sure but i checked the pump and it is not getting and power to it. I checked all fuses and they are fine, i switched around all relays in the fuse box and still nothing. Can anybody help me?
Thanks!
Hi if theres no live to the pump three things spring to mind fuses and relay and fuel cut switch has tripped so you need to check at the relay if there is a live and if not it is the cut out switch if its live at the relay by pass relay by connecting its live to the feed for the pump it should start if the pumps ok if so replace the relay yates210456
hi the two main problens with the ecu,s accessories are engine temp senser and the crank postion senser my problem would be with this is no engine codes being stored on earlier models they did not always register this may be the case with the cherokee,s as it would make sense for this to be faulty as the fuel pump would also need to know when the engines pistons at the top of there stroke your can do a resistence test on the crank position sensor to see if its faulty depending on the senser they vary between 200-400ohms and 800-1200omhs a sensor that is ok will be between one of these readings check it disconnected from its loom let me know how you go on paul

My main concern is that there is NO POWER to the electrical and fuel of the car. A local mechanic told me "CHEROKEE'S" are known to have a problem with the "CRANK POSITION SENSOR" I'm not to sure if this is common but I am thinking to order it/replace it and see what happens.
Problem fixed it was the "CRANK POSITION SENSOR".
thanks for your help!!!!
2000 Jeep Cherokee cranks but will not start. I checked for 12 volts
at the coil rail and it's not getting it there. My Manual said then to check the Auto shutdown relay so I removed the cover and watched the relay while my son turned on the ignition. The relay energized. The manual then brought me to the PCM and said to have it dealer tested. Another area to check is the crankshaft positioing sensor mounted
where the distributor would be if it was a model before the year 2000.
I still haven't got it started. Has anyone out there got a positive fix for
this problem?
