GM 6.2 and 6.5 Diesel Mechanical IP List

The number one thing at the core of most all the cascading issues of the GM 6.5 Diesel is the lift pump

Don't waste time testing fuel pressure - junk the OEM pump and replace it with a Sure Cure Lift Pump solution - 95% of the time it will start if the batteries are fully charged to crank the engine at 200 .rpm and above and you have good glow plugs

If not the PMD Is blown or has loose connections and / or a bad calibration resistor -  actually caused at the root by the lift pump too - replace or repair it by replacing the power transistors, and it will start.

The DS4 IP needs fuel pressure of around 10 to 12 psi to run and idle properly or it will use assistance from the fuel solenoid with stra\ins the PMD heats up the Power Transistors in it and over time makes them fail - aka blown PMD.  With proper fuel pressure into it - the DS4 is a balancing act and needs very little electrical assistance from the fuel solenoid which is the "throttle" by wire and that saves the PMD and keeps the pump cool by recirculating fuel through it back to the tank and helps keep it lubricated internally.  So . . .  believe what you want and have been told or read elsewhere  . . .  you are wrong . . . 

95% of the time start with getting rid of the OEM lift pump completely.  This is GOSPEL - you need 10 to 12 PSI of pressure - not 5 or almost 5 or five will do - it won't 10 to 12 psi or you are killing the entire DS4 Injection Pump system slowly

Some people have had enough - and are converting or have converted their 6.5 DS4 to a DB2 Turbo - in which you will loose cruise control and can purchase an adapter for the CMP low and high resolution signal and an adapter for the stepper motor for timing so the transmission will still work properly and the Turbo can still be controlled by vacuum.  Any DB2 can be made to work, but should be modified for proper fuel flow, and you will need a DB2 injector line set.  their was an OEM version of a turbo 6.5 with mechanical IP and in the consumer sector were found as 92 to 93 engines.
