HELP!!!! I am getting injector module codes

[DND58]

Tiny, on the inboard side of each valve cover, you can see a wire harness connected to the valve cover. You can disconnect this harness, and use an ohm meter to see if you may have trouble under the valve cover.

Test on the pins going into the valve cover to read resistance from the glow plugs and injectors. Getting good contact of the test leads to the pins can be a pain.

G G I I C I I G G

Test between "I" and "C" to test the injectors, should be less than 5.0 Ohms.
Test between "G" and battery ground to test glow plugs. Should be between 0.6 and 2.0 Ohms.
