Sudden Loss of Power - 1994 Pickup 22re
I was driving home from work yesterday in my 94 base model pickup. Went to give it a little gas and it just bogged down to nothing. Thankfully I was able to make it off the freeway. So once i was safely pulled over she was idling super rough and as soon as I added a little throttle the engine would stall. And now the truck won't start at all. Since the power loss occurred when I depressed the gas pedal I started looking on the intake side first.
Any input from you guys would be really appreciated! and I'll make sure to keep the forum posted as I proceed here.
So far this is what I've found:
It looks like this screw is missing. Not sure what this does here or if it might be the problem?

Alright...when I crank the starter I smell fuel like it's flooded. If I let it sit a few minutes and crank it again the truck will bite like it wants to start, then die immediately.
Next I jumped Fp and B+ terminals in the diagnostics port, turned the key on, and did not here the fuel pump working. So it looks like it might be the fuel pump.

Problem Fixed! It ended up being the fuel pump. Sorry guys no photos this time.
I did jump the Fp and B+ terminals with the key in the on position and could not get the fuel pump to operate.
Then, with the key in the on position, I moved the vane in the AFM and could hear the relay by the ECU click, but not the fuel pump did not operate. By this point I was 99% sure it was a bad fuel pump.
Since I had nearly a full tank of gas, I elected to remove the bed. This was super simple, and I was able to do it by myself. On my 94 pickup there are 8 17mm nuts and associated bolts to remove and 3 screws to the filler neck. I simply lifted and walked the bed back far enough to access the top of the fuel tank. Here's a link the the video I watched on how to remove your truck bed.
I was super relieved to have the truck start right up after the new pump install.
