Fuel Management system
Okay, Iv'e got a new 355 cu in Chevy sitting in my garage awaiting the perfect weekend to swap out in my 91 Chevy P/U. I bought an Edelbrock MultiPoint Fuel Injection conversion and high pressurepump 2 years ago while waiting for the engine work to be completed. This past weekend, I thought I would install the MPFI on the old engine to debug it prior to installing the new engine. I had a friend come over and we removed the bed of the truck to access the tank to install a high pressure pump and to replace the fuel level sending unit. That was Sat. On Sunday, I finished up by actually swapping out the intake and finishing the fuel lines. Everything went by the numbers. I started it up and let it run while I was cleaning up the garage and tools when after about 45 minutes, it died. I didn't hear the pump running any more so I checked all the circuits to verify that it actually was the pump. Indeed it was. I then bought an in-line Carter P5000, which I was told would "draw" through the in-tank unit. The truck started up just fine but after a few minutes, I could hear the pump making a strange noise which came and went every few seconds like it was encountering a restriction (probably on the inlet side). While the noise is the loudest, the engine seems to be getting enough fuel to run normally. While it is quietest, it barely has enough to idle. Any ideas?
