P1689,P1693,P0237
Noticed a few weeks ago my crusie control stopped working. Since last weekend i have had intermittent starting problems. The following codes appear on the code reader: P1689, P1693, P0237. After i get the truck started, it runs fine, although it seems to be lacking a litlle power. My truck only has 70000 miles on it and it seems a little early for the injection pump to be going out? Any suggestions?

P1689 - No communication between the Injection Pump and ECM (Not a good thing!)
P1693 - Companion Code, it will appear when there is a code in a controller
P0237, Boost sensor low voltage signal
What kind of modifications if any are done to the truck? Once it is running, how does it perform?

I strongly suggest getting a fuel pressure gauge on that truck. Even bone stock they barely have enough flow to the injection pump. Too little flow (pressure) and the $1000+ vp44 is toast. Knowing fuel pressure can determine how well the engine will perform. 10 PSI at WOT is the minimum value your looking for.
