Running Issues

My '98 4runner had the engine keep shutting off after only a few minutes of running and at first we thought it was the fuel pump and then the fuel injectors and all has been replaced with new parts I even replaced my old fuel tank that had definitely seen better days even though all parts mentioned were original they have all been replaced with new parts and yet she won't run for more than a few minutes still....any suggestions? She's been out of commission since June 2023. Any help would be greatly appreciated!

 

Fuel pressure regulator? Fuel filter? I would think there might be a port where a direct reading gage could indicate fuel pressure while the truck is started, and what the pressure is when the engine stops running.

 

Yes, you hook a vacum gauge up to the regulator. very simple test. Maybe an eletrical tune up, plugs and wires. Get that out of the way.
