Truck wouldn't start this morning, I could tell it wasn't getting any fuel. I checked pressure going into and out of the fuel filter, both were good. There is power going to the injector solenoid. Is there any way to tell if it is a bad injector pump (before I spend $400 on a rebuilt one)? Thanks for your help, Ben
Pull the return line off the top of the pump. Then remove the black adaptor fitting. Put the breather back on. If the truck starts, the pump is bad. Yes, fuel will fly around a bit, but it's a sure diagnosis of a bad pump.
