Lml duramax crank no start.

The first thing you need to verify on a no-start condition is fuel pressure, so hook up a scan tool and check for any DTC codes.

If there are no DTC codes currently set, log Fuel Rail Pressure with the scan tool while you crank the engine over.When cranking, the FICM has full control of the fuel injectors. The only input the FICM uses at this time is the engine speed signal from the ECM. The FICM monitors the signal along with the injection request signals from the ECM after the engine is running. If there is a problem with this signal, a DTC could set.The truck will fire up and run flawlessly after the new CP4 is installed, but when you turn it off, it won't start again.
