Hi, First off I have a 1991 Toyota 4X4 pick up with the 22RE engine. The problem is the truck will start then after 2 to 5 min it dies. I can hear to fuel pump running than it shuts off. Replace the fuel pump, strainer and the filter. Same problem Starts runs for a few min than fuel pump shuts off truck dies. Thanks

See if there are any stored trouble codes:

Test the AFM:

and/or try the fuel pump test jumper:

Ok, I did some more test and here is the results. Whem I jump the +B & the FP the pump constantly runs and truck runs with no problems. Soon as I remove the wire the pump shuts off and the truck dies. So I went ahead and bought a reman AFM ($280.00). And same problem. So I returned it. Not the fuel pump. Not the AFM. What next. It can't be that hard can it. Any more Advice out there?
Thanks..
