no talkin to v44/fault code p1689?
#2
That would be a VP44 issue normally. But there have been a few occassions where the 1689 code can be thrown by a bad fuel pump relay in the main fuse box. If you pull this relay you can crank you truck without it starting. but it will throw the 1689 code in the ecm. But more than likely the vp is on its way out
P1689 - No Communication Between ECM and Injection Pump Module Data link circuit failure between ECM and fuel injection pump. Low power, engine derated, or engine stops.
