Fuel Problem

[minimarshall]

I have a 97 chevy silverado 5.7L 350 with new spark plugs fuel pump and filter and it stalled while goin over some train tracks. We replaced pump again after not turning on.. still nothing so we replaced the camshaft sensor and tested fuel pressure and its all good. we can poor a small amount of fuel in the intake and it runs for a sec. or two. What can i do?

What is the fuel pressure with ignition on and engine off?

its 62 psi

If the plugs are firing, I'd suggest looking at the connector at the injector pod.

Pressure is good. Like Blue Bowtie said, you need to look at the injector pod.

There is an updated injector pod that converts from CPFI (Central Port Fuel Injection) to MPFI (Multi Port Fuel Injector). The MPFI kit comes with 8 injectors instead of just one.

Does anyone have a link, or anymore info on what this upgrade exactly is?

Our truck has a Central SFI system. Is that the same as the MPFI because this system contains 6 injector ports which is housed between the upper and lower intake manifolds. Could my problem be the powertrain control Module (PCM)
