There is a fast idle solenoid(external) and a cold advance solenoid(in the top of pump.) You can check the fast idle by unplugging and applying 12volt to it the plugger should kick out. The advance solenoid can be checked by unplugging and plugging back in w/the key on. It should make a slight short buzz when power is supplied. Also check and see if you have power to these items when the key is on and the engine is cold. You should have power to the temp switch on the coolant crossover, then on the other side to the componets. The trouble shooting guide(hard starting) explains things pretty well. I find the same problems w/the manuals also, but the operations are close to the same. The thing I can find is the temp inhibit switch for the glow plugs. I know it works but it's no place to be found. Anybody have any ideas?
