Fuel pump not working
Hi there I am new to Jeeps and new to this forum and are looking for some guidance and am happy toi give any in the areas I know
I picked up my 2008 4 door Jeep unlimited last week and have just got around to messing with it.
It was a water damaged jeep but I have had over 15 cars and trucks that have been classed as the same and had a great deal of success with all of them.
this Jeep is baffling me a little,, it will start right up if I put fuel direct to the inlet manifold until the fuel has burnt up, there seems so to be no fuel pressure at the rail and I do not hear any noise coming from the tank when the key is turned on.
I did some research and saw the jumper trick shown on another post so I did that,,(https://www.jk-forum.com/forums/jk-e...-relay-274779/) nothing, I also looked at connector C5 for the blue orange wire but dont have one visible.
I did split the TIPM and cleansed all contacts and looked for any water ingress and saw none, they are pretty well sealed, I then crawled under the Jeep and just want to be certain I located the fuel pump?
What I saw was a black plastic canister about the size of a shoe box with a white nylon cylinder on one end of it and 2 fuel pipes coming from it, there was one electrical connector with 2 wires on it, I took a good 12V battery and applied power to the connector, nothing happened, the canister looking thing was the drivers side of the Jeep about 2 or so feet un front of the rear axle, I also traced the wires to a split in the loom, one side goes to the fuel tank assume that's whats under that long cover down the underside of the passenger underside of the Jeep
so I am open to any ideas now? I know the Jeep has some other electrical issues but know it will run if I can get fuel to the fuel rail and plan to sort out every issue until the Jeep is right again.
Any pointers would be gratefully accepted
thank you
