I know that these are related to the pump but I’m not convinced it’s that to fault as my van originally died so I got some one to do the timing he retarded the pump all the way and if any thing it run worse and smoked a lot so I changed the injectors that didn’t help so I then advanced my pump As much as it would go it run but was abit lumpy I then a few days later left it running and it turned of it won’t start and showed these codes I’m thinking maybe it’s still timing related but just want reassuring before I change the pump and that dosnt fix it thanks Again for the help.
It has 140k miles so it is overdue but by the looks of the timing cover some ones had it of before judging by the broken bolts :/ also when he retarded it he undone the locking bolts and turned it anti clock wise I believe that’s retarding so I advanced it by going clockwise but I didn’t know if incorrect fuel timing would cause these codes as originally it said over fueling so I thought it would of said that again
1563 is fuel pump timing solenoid 1664 is ecm on the pump just had the 1563 myself and my van rattles. still got it but doesn't tell me anymore as my problem was just fuel filter.
