Default Low Fuel Rail Pressure at start up Long crank

My truck is slow to start. The fuel rail pressure is low at first while cranking then the pressure builds up in 3-4 second into the crank then starts. Any ideas of what it could be. ??? I've had electrical issues with the alternator over charging( 16V )replaced that today.

could be a number of things, High pressure fuel leak, High pressure fuel pump issue ect. Is your engine oil overfull? That would indicate a leak.
