can anyone help me please my xj quit running today out on the trail, it just died and wont start back ive checked all the fuses ,coil,grounds cps is new put a new fuel pump in all on the trail, it will start with a can of starting fluid and run till it runs out but i checked the wires to the pump and they have no power to them to the pump, could it be the ecm, some say ballistic resisitor but mine does not have one being a 94 xj 4.0 ho anybody know or run across this problem? Thanks

 

Fuel pump relay...maybe

 

Sounds like a good case of "fuel pump gone out". Seen it happen a few times before! I'd do what you can to get off the trail and find a tow home. Relay or pump, still gonna be a ***** if you don't have the right stuff to fix

 

You got 7 relays in a row under the hood? Fuel is second from the rear I think. The one if front of it is the ASD, but the one infront of THAT is just the AC clutch. Try swapping those two.

 

fuel pump is new guys i replaced it on the trail in the mud, i moved the relays around the fuel pump relay is clicking when you turn the key on but still no power to the pump, ive got it towed home made it out safe

 

thinking it may be ecm ive checked everything even jump the pump and still nothing...

 

Meaning you connected the battery directly to the pump?

 

got it running gas tank took a hit from a big rock and slid it back a few inches i put it back bolted it down some more and it fired up....
