4.3L XJ

Might I suggest not throwing any more money at it and do some good old fashioned trouble shooting first. You say the fuel pump is not working? Get a test light or ohm meter and see if it gets current. I bet it is not. Then go to the relay. Is it getting power from the battery and the ignition. I bet one is missing, probably from the ignition. Any power from the ignition to the coil? I bet not. You will probably find that there is some problem in the column somewhere.

I'm thinking the security system has shut down the power to the fuel pump and ignition

i have done everything you said numorus times,,,like in the op ive said ive had this thing for 2 years,,working on it on and off,,,ive checked and changed everything that could affect it besides the pcm/ecu.


and the security thing was what ive been leaning twards for a while ,,but since im new to the cumputerized jeeps im not sure what else it could be..

so nothings getting power?

on my ford getting it to start is as easy as putting a wire between the radio(or accessory) fuse and the cigarette lighter fuse..then everything should beep and happen normally then just jumping the solenoid

Duramaxfanatic1

i think its a relay for the fuel pump or something along those lines
