tech question. Holley sniper fuel pump not spinning up when I turn the key?
Where do start, pun intended.
I did check the fuse.. 85 AMC 258 i6 / 4.2l

Got an event tomorrow and heading to work now. Guess I'll be wrenching in the middle of the night...
Again 😅

Maybe. Mine was a ground problem out in Moab. And other problems.
 
Ok. Putting it all back together.
Found TWO dangler wires 🫩😮‍💨
I can't find what they go to, plz help. I missed the va4wda trail ride but still wanna go to the event today 😕 these 2 are of the same wire.. the other has a spade attachment. Thought I got a pic, brb

Ok, pretty sure I figured it out #TIL #iykyk, so the oil pressure unit wire is off and the fuel injection will cut power If oil pressure drops below five psi, so with no power going to the sensor no power would go to the electric fuel pump..
My ??? Is, does anything attach to the top "of the one in the pic"? It's a purple wire btw.
