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.

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.
