I have a '94 Chevy Blazer Tahoe S-10, 4X4, 4-door V6 Vortek(x) engine. My problem is that when I start it in the morning....it kicks over & starts in a flash and will run forever.......until I shut the engine off say 10 minutes or 2 hours later. Then it won't start until hours later or the next morning. It cranks just fine but won't re-start again until it sets for a long time.

I tried to see if it was getting any gas at the engine by flooding it (depressing accelerator pedal to the floor a few times) but couldn't smell any gas at all at the engine and the fuel pump and filter was replaced 5-6 years ago but I would guess this isn't the problem since it'll restart every time after a long wait.

I'm thinking fuel pump relay or filter but I'd sure appreciate any suggestions you may have....Tks

 

You need to get a fuel pressure tester to test the pressure & leak down rate of the fuel system. It should prime to >55psi and should remain above 50psi for 10 minutes after the pump shuts off.

5-6 years is an eternity to a fuel pump in these things.

Also, just an FYI, the throttle pedal only connects to the throttle body on the engine. It does not cause more fuel to be sprayed into the engine directly so it wouldn't cause the engine to flood.

 

Tks swartlkk for the reply and if it's the fuel pump is it advisable to put an electric fuel pump in-line with the existing fuel pump/gas line? To save some future expenses/problems.

 

I would not recommend making the system more complex than it already is.
