Start with the fuse box under the hood. Is the fuse/relay for the fuel pump blown or bad?

Yup me too, or a harness is unplugged or wire was pulled out of a plug. I'm willing to bet its going to be something really (Captain) Obvious.


Is the fuel pump on a fuse or a relay?

its a relay... no ac relay to swap with. i feel a click when the engine turns over. I know when I find this it will be a V8 moment


Try swapping a headlight relay. Yes palm to forehead V-8 moment indeed. LOL


ooo that's a thought now real dumb question (ive always had ford and dodges) under the clutch fluid is a small black wiring harness, a black box.. I find no information on what this black box is. Mounted to the firewall... ideas?

If I remember correctly I think that's the ABS module. Oh and never a dumb question.


thanks... going to rip more apart tomorrow. too dark out now.. V-8 Moments typically come at 8am. LOL


I totally understand. Sometimes walking away from the problem, before you friggin lose it and start smashing and breaking things(not that I've ever done that LOL), for a while is best. Look at it with fresh eyes tomorrow. Let me know how it goes. Hhhmmmm I wonder if we have any V-8 in the fridge.


Ok so after testing every damn wire it was the four day old freaking fuel pump.....

Yes thank you so much for your help... Moods like dummy ex put a new fuel filter in my sons truck with out draining out the old fuel... Truck sat for seven years


No problem. Oh geez! Well, there's your V-8 moment,LOL.
