cummins n14 no start problem

[Mike_NC]

The engine will crank but will not fire. The fuse going to the ecm is blown and keeps blowing. Is the ecm shorting out? Need some advice, thanks.

keep blowing at start up ore when you tirn ignition on? it is important.
what fuse? in positive wire (in batery box?) ore negative wire near ECM?

Could be bad solenoid. Unhook wire from solenoid and see if it blows fuse.

It blows when the engine is being turned over, the fuse is at the ecm.

[Mike_NC]

Engine turns over just fine but will not fire, acts like it is out of fuel.

[Mike_NC]

Fuse in battery box is good.

it is bad engine grounding issue. Voltage drop on starter negative wire, fix it, till engine ecm is not damaged

Update: Never could figure out why the ecm was blowing fuses, all wiring checked out along with pin connector checks for the injectors drivers. Ended up finding the fuel pump as only putting out 2-4 psi of pressure while turning the engine over. The metal drive gear behind the spider gear was really loose and the spline on the shaft were worn heavily. We assumed the gear was slipping.
