I am sorry for the long wait
when cranking it over is there fuel at the injectors ?
these had pump issues yes
how long has it been sitting ?
if you remove the fuel line off into the injection pump when cranking it over does fuel come out of the line ?
ok let me know
ok tighten that line up and remove the fuel line into the injection pump when cranking it over do you have fuel out of that line ?
ok see if there is fuel at the injection pump from the fuel feed line when cranking it over
the fuel loine that connects to the injection pump the fuel feed line at the injection pump
pop off that line and see if there is fuel out of that line at the injection pump when cranking it over
no it is mounted under the upper intake behind the oil fill tube
this is the pump looking from the back side of it
should be the front of the injection pump accessible behind the oil fill tube area with a rubber fuel line on the passenger side front corner of the injection pump
seen and reached from the front of the engine
no it bolts to the back top of the timing cover and is run off the timing gear
ok if there is fuel into the pump and NO fuel at the injectors and all the fuses are good and with the key ON the check engine light IS lit up in the dash then the odds are the injection pump is bad
we have seen crank sensors but you would need to connect a scan tool to the truck and see if there are any codes and see if when cranking it over if you have an RPM signal when cranking it over
if NO crank sensor codes and you can view data and can see a crank RPM then the only thing left is the pump
closure time code ?
tell me the code numbers
if no codes and no fuses are blown and the check engine light is lit up in the dash with the key ON the only thing left is the injection pump
