My Suburan with 225k miles was running fine up to the time the trouble started. It was up to temp when I shut it down. When I attempted to restart, it would run for 2 sec’s and die. I could pump the gas to keep it going another few seconds. Had it towed home. Replaced the fuel filter and now I could keep it running if I would gently pump the gas. Replaced the in tank fuel pump, what fun, and it ran perfectly for 5 mins or so. Shut it down and thought I had fixed it. An hour later, I went out to start it again and it was back to just running if a I feathered, gently pumped the gas. Then I replaced the Idle Air Control and Throtle Position sensor. Still no luck. It acts this way at any temp. I tried to move it by the “keep” pumping method, but under load she just wants to stall. Read the codes and nothing comes up. I feel this is a fuel issue due to the fact that the filter and pump made changes. Now I guessing presure regulator? Any sugestions? Patrick T ---

Guessing is costing you money. Test the fuel pressure. ---

Where do you test for pressure? This has a throttle body with a fuel feed line and return line? ---

Test at the fuel filter. ---

Pete, I just changed the fuel pump so testing at filter would bypass the fuel pressure regulator? I’m assuming with the new pump, I have good pressure on main line. ---

I guess I should have made myself clear. You’ll need to use a fuel pressure gauge that has two lines so the fuel flow isn’t stopped. It will attach to the pipe and filter. I think there may also be an adaptor to go there to use a “normal” FP gauge. And I never assume. New means new, doesn’t mean good. So when you changed the pump, you also replaced the hose from pump to pipe? ---

Pete, Yes, short hose came in the kit. Removed, cleaned fuel pressure regulator. Spring was in tact and diaphrame had no rips/holes. Reassembled I have friend coming over today to check the pressure.
