Update your sig and check the FAQ section under the 6.5 topic. Is your FSD remote mounted?

Since your truck is a 95 model,you can get the codes off your computer very easily.This should help you.Here is the link http://www.kennedydiesel.com/ (http://www.kennedydiesel.com/)Top right of page click on tech tips,then 6.2-6.5 tips and finally read codes.

Pump problems I'll bet

ok...heres the codes as follows 13,18,35,54 and my FSD is not remote mounted....any help that you can give will be well appreciated.....Thanks

Sounds like a pump problem. All of those codes have to do with the pump. I would check all of the connections on the IP and make sure they are clean and tight. I am not real familar with the DS-4 so hopefully someone who is will chime in.
