Jumper B+and Fp at the check connector, turn the ignition key to the on (run) position, if the circuits are all intact you should hear the fuel pump running and fuel running through the lines. Try starting the vehicle, if it starts with the fuel pump jumpered then the AFM fuel switch might be faulty or you have a problem with the circuit opening relay or wiring. that soulds like these components and wiring are ok.

If you hear the fuel pump running but it still won't start, then replace the fuel filter. almost always points to a plugged filter. If you change the filter but still doesn't run the way it should, check the fuel pressure in the system (33-38 psi.) If it's a new fuel pump and you can't get the pressure, then drop the tank pull the fuel pump assembly and check the fuel pump filter (pick-up screen) it may be plugged. It's a 92 almost 19 years old if it is the original tank there may be crud in it.

Thanks Hadmatt, was messing with it this morning, had to give it shot of ether started up idels fine ...as soon as i accelerate she boggs down to almost dying, let off gas and runs good,,between not starting on own and the bogging down, seems starving for fuel at high demand? Gonna try your jump test... think its f.y. to f.y.i. on 92? thanks again!

sounds like a plugged up fuel filter or fuel pressure regulator to me. maybe an 02 sensor but doubt that since it won't start to begin with.

COOL, got two more things to try.... and learn! Thanks guys.

Ok fuel pump does run with jump wire. tryed fuel filter off one of my xtra 22r parts motor,, seems to have taking away some of the bogging.. so think ill get a new fuel filter. find out this morning if she starts without ether.

Could clogged/ dripping vs "spraying" fuel injectors cause such a problem.?

Cold start injector/ timer causing anything to do w/ 30/ min start up?

not sure if these apply at all but those are the other places besides, filter and pump, my brain goes.

Hey I know this sounds stupid but I just rebuilt my Toyota and am having some problems out of it. Can you guys show me how the fuel filter goes on my truck. It's a 94 22re. I feel kind of stupid asking but I am thinking maybe it's on backwards... Thanks guys!

im having the same issues just havne't fixed it yet i installed my filter backwards by accident (was in a rush) wouldn't start, so if it wont start it's prob backwards it should have it printed on the filter in and out . on either end of the filter

Its been a while, back with update... When i pulled bed off found the rubber fuel hose was crimped, restricting fuel to engine, it was smashed between tank and bed, The guy i bought it from said he just put a new fuel pump in..my guess is he pulled bed to do it and set the bed down on fuel line. She runs great now! Thanks for all posts,
