Your problem is a leak in the cpi pletium most likely the pressure line has a leak
had same problem with mine $45.00 PRESSURE LINE KIT AND $15.00 GASKET FOR PLETIUM and 2 hours labor problem sovled.
You can remove vortec cover and remove air regulator to look inside pletium. I had gas vapor on driver side . that is where fuel lines are. fuel regulator is on passenger side. turn key on and look in hole and see where fuel is spraying. taking pletium off you can again turn key on and make sure where fuel is coming from.
It reads at 70 PSI and still wont turn over....still not getting fuel to engine

now im not getting any fuel at all i have purged the pressure relief valve and theres a tiny amount of aair coming out but no fuel....fuel pump is still operational could it still be the fuel pressure regulator?
its reading at 70 PSI, then 69 PSI lastly 70 PSI from 3 attempts from turnover and again still no fuel getting to engine either, fuel pump sounds like its kicking on, can the fuel pump cause the Fuel Pressure to be too much PSI for the engine to start, like the pump doesnt have enough PSI to send the fuel to the engine but has enough after it passes through the Fuel Pressure Regulator ?
my problem with a v6 vortec is my fuel is going through the combustion chamber and the motor runs but gas is going right into the oil pan, my oil level get very high,
apparently the problem is with the fuel injectors; there is a part that is buried behind the exhaust manifold and under the engine. Can this be "cleaned" and put back in, or will a replacement part be required?
what is the fuel pressure
changed plugs and wires coil and stribader and fuel filter and still has a jerking when driving
