Fuel pump runs along time before shutting down. Replaced fuel pump and fuel regulator.

Good morning,

You need three things to run. Spark, fuel pressure and compression.

Check for spark at the plugs while cranking.

Check the fuel pressure at the schraeder valve on the fuel rail.

And lastly, check the compression. One of them will be missing.
