Buddy of mine has some codes, and i sure as heck have no idea! I dont know the year it is a VP. He said it has had a rough idea, at times then levels out, then cuts out, runs smooth,anyway here are the codes
1688
Po251
Po252
P0602
P1693.
Thanks for any help

Looks like his VP is on it's way out and possibly his ECM. Here are the codes:

P0251 Fuel Injection Pump Mechanical Failure Fuel valve Feedback Circuit

P0602 ECM Fueling Calibration Error

P1688 Internal Fuel Injection Pump Controller Failure

The P0252 sounds like a VP code, but I can't find any info on it

Nate thanks alot, the way he explanned it to me over the phone, my first thought was the VP was bad.

No problem. Without even looking at the codes it sounds like his VP is bad and those codes just prove it. It's a bummer that it's going out though. I'm surprised mine hasn't gone out yet (knock on wood)!
