there is water in the fuel, there should be a fuel water seperator in the engine compartment, look in your owners manual and it should tell you the steps to drain the water from it, it should take a few minutes

Its called the fuel pump cylinoide which is attached to the fuel pump. Unless the fuel pump is bad, you got an expensive part to buy around $2500 or the cylinoide is $900 whichever is broken. This is a know issue for GMC deisel suburbans 6.5.

Yes the security light has a lot to do with the vehicle starting and shutting off.This means the Body Control module is not getting the correct signal from the key itself or the ignition cylinder is not reading it correctly.What you can try,and this is something simple is if you have another key use it and see if it makes a difference.Sometimes a worn out key will do this.If this makes no difference then you will need to get the codes from the Body Control module.Usually a B2960 will come up.There is a service bulletin for this.It is number 01-08-56-002A.Has to do with checking wires and connections.Using an ohm meter for checking resistance in the wiring.Also using a scan tool for looking at the data.Let me know if you have anymore questions.Good luck.

Purchased a new gray Standyne Fuel Solenoid Driver kit with heat sink and extended wire harness. Mounted on left fender well and was able to do the work myself in about an hour. No need for injector pump work. Solved stalling issues and it starts up easier as well. These are all over ebay. Very common issue with this engine, and the GMC knuckleheads knew about it and didn't do anything to educate dealerships on a permanant fix.
