my buddy had his truck tested for codes today as the check engine light came on. they were p1689 and p1698. it said something like failure to connect ecm to injector pump??

what could this be and what is going out????????

 

I'm assuming that the truck does not run? Those are two death codes for the injection pump. HTH

 

Injector pumps out, or going out.

These guys seem to have good prices:
