Is it time for a new pump and where is the best place to get one.98.5 24 valve 3/4 dodge with five speed.1693 code with 1691 that could only be caused by pump failure right.

P1691 Fuel Injection Pump Controller Calibration Error Internal fuel injection pump failure. Low power, engine derated, or engine stops. Seems like your VP44 is going out for a dirt nap... Look for places with good warranty and low price. Try my small list of vendors... http://mopar.mopar1973man.com/cummins/dealers/dealers.htm
