I assumed there was no codes for no check engine light has ever shown, but I was wrong. There is a code P0216.I will need to get a differnt test gauge and install to see what it's doing when it decides to mess up, the one I have is way to short.

I have 2001 Dodge Ram with cummings engine. Has the following symptoms [*]Sometimes you get in and turn key and it will turn over and over and never hits a lick, but if you turn key off and try again it cranks right up. [*]Sometimes you get in and it cranks the first try [*]Does not matter if it's hot or cold [*]Sometimes it seems to be slugish (as in it will slow down on a hill and if you step on it, keeps slowing down), the next drive is just fine all the power you need. I have done the following [*]New fuel filter [*]Checked pressure and it's 21 PSI at idle, using the test location at the injector pump [*]Not sure about the following, it only pumps when cranking, should it pre-pump when you turn the key on? or does the pump only run when starting? [*]Soon as you turn key off, pressure QUICKLY (2-3 seconds) drops to 0, should it not hold pressure for a while after it has pumped up? Any suggestions?
