Doing a carb'do motor swap on a 91 Ranger with a 2.9. I have the motor in place, all the original wiring is just zip tied on the firewall out of the way. When I turn the key on the fuel pump isn't kicking on. I drove the truck in Friday and never have had a fuel pump issue. Help!

So you ripped out the engine wiring, probably the computer, put a carbed engine in place of a perfectly good EFI system, and now the fuel pump doesn't work?

Is that correct? Just making sure I have the situation correct.

No ripping and tearing, just neatly unplugged and tied up wiring harness so it can go back to FI if I so choose. Happened to get a carbureted motor for the right price, so that's what I'm going to run.

And I figured it out. Had a "d'oh!" moment. Inertia switch tripped at some point while working on it.
