My truck died while driving about 50mph with no load. It may have run out of fuel but gauge read 1/4 tank. Pulled it home only 1 mile. Got fuel spray from main line going into VP44. Lift pump seems ok(Raptor pump) Fuel pressure gauge has been not functioning for couple months. Could not trust it. Cracked lines 3 and 4 no fuel to injectors. Is there a way to bypass the ecm to make the truck start. I know Cummins has a little box you plug in to bypass the electronics somehow. I just want to test the VP44 to see if it is bad or if it in the ecm . Thanks ahead for any help
