I’m looking for someone with no problems to run a test or chime in.
1996 - 5.7 350
I know the documented GM Spec is (60-66psi). But it seems this is also Key on, Engine off. Everything I’m finding in forums are post with people having issues, some replacing pump and same pressure, same problems. (50’s)
I would like someone with zero issues, same engine do a FP Test with engine running and post results. I’ve replaced every GD thing aside from the Fuel pump,(EGR.FuelFilter.MAF, Plugs.Wires.Rotor.Cap.Ignition Coil.IAC.CrankShaftposition sensor.EngineCoolant Temp, New Fuel spider Injection assembly with new Fp Regulator and I swear I’m not spending another $20 without guaranteed results.
At this point I’m just going to LS Swap it. I don’t have a nice REAL mechanic scanner just an OBD2, and 2 local shops have been unsuccessful in diagnosis. I’m not even willing to pay a diagnostic fee, I’d rather just go get a LS. I live in Houston and they Dime a dozen round here. Never thought I’d end up at the Parts Cannon storyline but well it happened. Engine is good! I wanted to keep it OG 350 till I got a square body. Any way, any help much appreciated. Maybe this was more of a rant? Still curious in good running Fuel Pressure numbers though, if that’s it I have to replace anyway with LS swap
