96' Explorer Fuel System Troubles.

[J.Brown]

Good Morning would like to pick ya'll brains on a problem I'm having issues with.

A few weeks ago, I bought a 96 Explorer XLT 4.0L 4x4 for an extra vehicle, more for the wife's Rabbit business. I paid $250, and it was thought that it had a locked up motor. Them thinking it got me the truck at a lower then expected price. Dropped a new battery into it, and tried to start it, just a loud ding as the starter hit the flywheel, motor didn't turn over, tried twice more. Same thing, washed the age off since it had the black residue from sitting under the tree, went to roll the windows down and went a little to far on the key, motor turned over.... Surprised at this I tried a couple more times. Motor seems fine, no dis coloring in oil from sitting, no rust coloring in radiator.

Truck won't start, checked relay, and fuse. Nothing.... Next tried to hear the fuel pump, nothing. Replaced fuel pump, cleaned out tank since it had at least 2year old fuel in it. Put tank back in with new pump. Tired turning truck over, and it fires up. Let it warm up for a few secs not wanting to hurt the motor with the old oil, shut the truck down. Close everything up and go inside. Once wife gets back from store, tried showing her that it would start...... Nothing. Won't start, no studder or sign of trying to kick over except for motor rotation. Check fuel rail, no pressure. Checked pump that was just changed out, working. Replace fuel filter under driver side floor pan. Done.

But even after that, even after trying to pressure the line back up, it doesn't spit anything out of the test point. When I removed the old filter the fuel looked clean. No junk in it. Spilled from both fuel lines before and after filter. I made sure to place the filter in the right way so it's not reversed.

So around $400-$500s later no running truck, didn't see any thing extra like a high pressure pump after filter like I had on a 87 Ranger I owned. Not sure what could be the problem from here, unless the test point is damaged and isn't closing so it will pressure up. But I have no clue. Any ideas would be much appreciated.

Thanks.

Confused:
How do you know the FP is working if there is no pressure? Maybe it makes noise but still has an issue? What brand fuel pump did you use? Is the fuel pump relay good? Is the PCM relay good?

Do you see a check engine light when you first turn the key?

If you can hear the pump, I've taken the filter loose before and put a rubber hose on the output end and run it into a jug, then switched it on, I've heard, though never seen, of pumps running but not pumping.

Maybe gunk in the tank has clogged the filter on the fuel pump?

I'd test the pressure at the fuel rail with a gauge so you know exactly what you got. Or you could pop the line off at the fuel filter and attach a piece of hose running into a container and check for flow.

Either way if the pump is running it sounds like something is blocking the flow.

I think I just had the same issue. Go to the passenger side kick panel. You will find the inertia switch. Make sure it is not tripped or pull the carpet back and disconnect the harness. There should be three wires in the connector. Place a jumper connecting the green yellow wire to the black pink wire. Kick the engine over and see if it starts. You may need to cycle the key on and off a few times to prime the pump. If it starts, just connect it back to the inertia switch firmly.

Got it working, the new fuel pump was bad, dropped the tank again and put another new one in, and starts and drive fine, thx

What brand pump did you use?
