I recently purchased a 2002 GMC 3/4 ton with the D/A that has 160k on it. I plugged my scanner into it the other morning just out of curiousity to monitor the boost. As I turned out of my neighborhood a trouble code popped up. it said lack of fuel rail pressure upon fuel enrichment. Has anyone ever had this problem or know what the problem is caused by?
Im guessing injector pump or regulator, but i want to figure out exactly what it is so i dont have to spend any more money than necessary.
Thanks.

Dirty fuel filter will also cause that on a LB7, but with that many miles, there are other possibilities...

Is there any avoiding this problem, or should I just start saving? Also, if the injectors do go out, anyone recommend any certain kind to buy, that will last.
