Put the truck on the laptop and coming up fault 21
Fuel injection timing solenoid/injector needle lift sensor malfunction, the question is how hard are these to put right

Had the same problem (started thread on it Code 21:thumbs) mine turned out to be a mix of water in the fuel & a partly blocked fuel filter:doh air getting into the fuel via a bad fuel line is another cause

Quite pricey as well last time I checked, doesn't it usually mean new no1 injector?
