I have a 2002 ford f 250 powerstroke. it will hardly start and runs poor i pulled the plug out of the valve cover gasket truck died so i started it back up pulled the other side truck stayed running i tested the wires and the glow plug wires will get power and the injector ones nothing. i checked all fuses under das no blown fuses. any answers? thanks

 

IDM under drivers side fender, How ever check the wiring all the way back to the IDM

 

Sounds like your UVCH is loose on that side. The wires in the connector will not show power. They are this configuration. G-G-I-I-P-I-I-G-G.

The G is for Glow Plug

The I is for Injector Ground

The P is for Injector Power

Pull the valve cover and I bet you find the UVCH is loose.

Here is a web page to read about it too. » TB 103: 1994-03 Ford 7.3L IDM Replacement & Diagnostics

 

Also Ohm out your Injector Coils a bad one will shut down a hole bank.

 

ill check these things and let ya know

 

Take the plug apart again and check the pins for blackened or burnt pins. This can also cause no power getting to the injectors. A loose connector can cause arching then it burns the pins.

 

got it thanks it was the harnes under the valve cover came un pluged. thanks
