welcome to FTE
if you want to check the harness start at the IDM and work your way to the valve covers (VC)..most common spot to chafe is where the harness goes over the driver side VC...you can also ohm out the 9 pin at the VC for a short under it...here is the pin out and spec's
Pin Out
G G I I C I I G G
G=Glow Plug +
I = Injector +
C= Injector Common
***The injectors fire with a 115VDC signal from the IDM do not pierce to wires to test.***
Ohm between "I" and "C" to test the injectors, should be less than 5.0 Ohms
To check glow plugs Ohm between "G" and battery ground should be between 0.1 and 2.0 Ohms
