A fuel pressure gauge can be your best friend on a vp-44 injected truck like yours. Would be a wise investment if you dont have one yet.

This was going to be my first suggestion. I started my Cummins addiction with an '02 very similar to that one. Now, 5 trucks later, I ended up with an '03 Quad cab. Wouldn't trade it for anything, except maybe a Mega somedays.
