My 2002 jeep grand cherokee 4.7L is not getting fuel to the engine. It has a new fuel pump and filter. I checked the fuses all good. What else am I missing that may csuse this. Thanks

You checked the relay? Are you not getting any fuel to the rail?

Can you hear the pump kick on when you turn the key to 'run'?

Getting spark? Assuming all else is good (relay) then I would suspect either a cam or crank position sensor.

The ASD relay feeds power to fuel pump and injectors.

I had a similar issue (starving for gas). And thought it was a clogged filter. Everything else seemed ok. When I crawled under to get to the filter, I noticed that the line out from the filter was kinked, and a nearby wire harness was knocked out of its retaining hook. I do all the work on it, so I know it was not there before. I guess when I drove over some gravel one rock flung the right way and knocked the harness out and hit the gas line. Spliced it with fuel injection grade hose and works fine.

Keep us updated... You can just switch your starter relay with your fuel pump relay and see if the pump primes and then if the Jeep cranks. If the fuel pump primes and your Jeep doesn't crank anymore then you know you have a bad relay, at least.

I tested,the relays and they are good. I even switched them out and got nothing. I can get the engine to turn over just no fuel going to the rail.

Is your ASD relay energized at ignition on?

This could be a stupid idea

however
when the fuel pump was changed, did the fuel pump get plugged in
or/and
did it get plugged in properly

good luck

Im going to double check the plug but I remember plugging it in until I heard it click. Also going to replace the ASD relay. I will let you all know how it went.

Make sure the fuel pump is getting power as well.

At the filter, if the connections are not tight, they can do the no-fuel delivery issue,...I made this mistake.


Next question, will it run with starting fluid sprayed down the intake? (Just to be certain it WILL run.)
