92 Ranger 2.3L fuel pump bad?
Truck quit running yesterday suddenly and unexpectantly. It sputtered briefly and the motor total quit running. I pulled over and tried to start and it briefly fired but then totally quit.
Got towed home. And now testing to see what all to repair..Thinking fuel.
I don't get any codes from the tester with KOEO..just the good to go etc..no codes or the good to go 111..etc.
Guess this problem can't be identified without motor running.
My wiring diagram doesn't give me all for my Calif car..I don't see where the relay is but my fuses are all good, and I'm getting voltage when I crank the motor at that inside firewall switch on both its wires(incoming/outgoing)..forget what its called..Inertia Switch?..that will shut off fuel pump during accident or impact etc. And I've read that this switch is upstream of the relay(if I read that post correctly) so guessing it's the pump itself that is bad.
Does that sound right? Should I go ahead and pull the fuel tank etc and replace the pump? Or is there more testing I should do?
When I turn the ignition key on..the pump makes zero sound. That's not the way it normally operates. Usually with the key on the fuel pump comes on momentarily and I can hear it.
Forget how to drain the fuel tank etc..I don't see a drain plug?
Any ideas? I did it once many years ago..but forget how haha.
thx Tom

Bought a replacement pump yesterday and just now turned on the air compressor to hopefully allow my impact tool to loosen those ancient bed bolts. I did the best I could to get Blaster type oil on them, but hard to know how well I succeeded.
My plan is to loosen the bed bolts plus any electric connections that might be harmed in the process and instead of lifting and intentionally sliding back the entire bed itself, I'm hoping to see if I can use my engine hoist/cherry picker with a chain across the front area of the bed to lift it up enough for access to the pump. Meaning only lift the front of the bed and allow the back of the bed to slide around a bit as needed but not intentional slide it back or lift it..we'll see.
Don't know if it will work, but thinking if so it would be a good one man job method. We'll see.

Try hitting the tank in the area of the pump
with a hammer or base ball bat. Bang it hard
and most times the pump will start. This tells
me that it is for sure the pump. Have you checked
the pump pressure with a gauge at the shreader valve?
Will it fire with a little gas down the intake? I would hate
to see you change out the pump and find it was not
the problem like I and others have done a few times.
