So I have a no start issue. It starts for a split second then it just continues to turn over. It will run long enough to burn off some starting fluid so I know I'm getting spark. One thing I noticed is that when I clamp off the return fuel line, the pressure doesn't increase any further than around 60psi. I've been on here quite a bit lately so some of you know what I have recently done but I'll give the run down. New parts are- MAP sensor Pressure regulator Fuel pump Fuel filter Plugs/wires Intake gaskets I clamped the return line and had my dad cycle the fuel pump and I heard some noise like it was leaking somewhere, but I couldn't smell or see any fuel.
