Checking the ohms reading at the valve cover connector on the outside.
I = Injector
C= Injector Common
NOTE: The injectors fire with a 115VDC signal from the IDM. *** Do Not pierce the wires to test***
Test between "I" and "C" to test the injectors, should be less than 5.0 Ohms.
To check glow plugs Test between "G" and battery ground. Should be between 0.6 and 2.0 Ohms
If your readings are not within these parameters you may have bad injector, glow plug or loose connector under the valve cover.
Welcome to FTE. In addition to what Brendan said I would look at the TPS also.

If you go to the 'root' of this forum, you'll see a 'sticky' at the top of the listing of threads: Common Mods, Maintenance, etc. .... something like that. You'll pick it up as you go, but taking the time to read through that is well worth it. Take your laptop in the bathroom with you, just try not to let your legs go numb
