When the engine off and key on it only primes the system. It runs for about 5 seconds or so and shuts off. But in the start position and while running the pump should run constantly.


When you checked the fuel pump What was the fuel pressure at the fuel rail? and what is the pressure when running.


Constantlya bout 14 psi


Fuel pressure much to low the TBI 38-40 is correct!


I thought for carburetor engine it should be about 14

Your car should not be carbed


It's a 350 engine


And? 350 doesn't mean carburetor. But if you have one then someone has converted it. There is also tbi injection and tune port it could be.


Well thanks it's a carburetor
