Have Truck Repair Questions? Ask an Expert
hi im alex, do yo have a scanner you are getting the codes or are they blink codes?
ok thanks, ***** ***** recheck the last 8 digits of your VIN comes up invalid when i try and pull it up
244 is a engine data line code, will it crank and not start or not even crank
do you show oil pressure on the gauge when cranking
you replaced the HP pump or base engine oil pump?
does your scanner read data? what are you getiting for ICP if it does?
ok this will be tough then
does it sound like the injectors are cycling when you crank?
ok , does the glowplug relay cycle?
ok we know the ecm has power then, does it smoke at all?
ok i would check engine fuel pressure at the filter housing
ok so you have good fuel pressure, if you crank on it for a minuet or so do you get any other engine codes
what code did you have before that you replaced the HP pump 333?
ok well based on what you have told me the fuel pressure is good and you have no ICP codes so we have to assume that you are buliding ICP since we cant read it, looks like this is a tow truck those usually have high idle time which is terrible for the injectors so i would say injectors need to be buzz tested and more than likely they are warn out
any idea how many miles are on the injectors?
no its tough to sell injectors to customers when you have no real hard proof, but a buzz test is a good induction if you cant hear the injectors
very limited with a scanner as well which makes it tough
