96 ranger v-6 (3.0) - fuel pump not working
Hi - The truck was running and starting fine. Went to start it up to go home, and it just turned over, won't start.
I believe that I have it mostly figured out. I don't hear the fuel pump when I turn on the ignition.
- checked the inertia switch as best that I could: the button was pushed in, but I toggled it back and forth and
checked for continuity - 3 connections, marked as NO-C-NC, which I assume is "normally open-C-normally closed".
With the button in, the circuit is continuous between C and "normally closed", and with the button out, the circuit is continuous between "normally open" and C. I checked the voltage across the wires that go to C and NC, and I see
12V. I think all is well there..., but I don't quite understand why 3 wires...
- On to the fuel pump: not very accesible, ouch; I want to see if there is voltage at the electric fuel pump mounted on the top of the plastic tank. The problem that I have, is that I don't understand how to get the wires off of the pump! There are little pieces of soft rubber near the connector for each wire. Can I take these wires off somehow to check for voltage? I'll have to look at a wiring diagram, because I would have expected 2 wires, 12V and ground, but there are more.
If it turns out that there is voltage at the pump and it still doesn't pump (can't hear a thing) then is there anything else to look at, assuming that the connections are good?
btw, I checked the fuse, and it is good.
