Hello, my name is***** will assist you.
You more than likely have air in the fuel system. Continued starting should force it all out. Or you can key up the engine, depress the center of the schreader valve on the fuel rail, bleed it, turn the key off and back on, depress the valve again. After a few times, you should get good fuel from it.
A bad compressor , it should still idle.
Have you checked the fuel for water yet?
Did you reset break-in, by moving the shifter into FWD and back to Neutral several times?
Also, do you have a gauge that can read up to 120 PSI and screw onto the schreader valves?
There are a few tests to do. First is at the back of the VST. It should read 25 PSI at key up. Then move to the Fuel rail. Fuel pressure at key up should be 40 PSI, then drop and hold between 10-20. Cranking pressure will get up to 90 PSI. Air pressure cranking is 80.
Spark out out test using an adjustable gap tool. and compression.
