Looking for info on a 2001 dodge. I have code P0230(Fuel pump primary circuit malfunction) Truck will not start, followed by Code P1688(Internal fuel injection pump controller failure) when I tried to restart. I`m hoping its just the lift pump, so I picked up a fass pump $375.00. I hope its not the injection pump also $1500.00+ What do you guys think?

 

check to make sure all your electrical connectors to the injector pump are fully connected.

good idea on the FASS as well, you will not be dissapointed

 

Well first code is gone when I installed the fass pump, but the P1688 code still comes up even without cranking. Guessing I need a injector pump. They are expensive.
