Glow plugs not turning on .
Over the last couple weeks I have been having a hard start problems.
Normally after it sits over night , but not always.
I have noticed that when it starts without problems, when I turn the key to the on pos. the voltage gets yanked down some by the glowplugs being on.
When it wont start, the voltage never pulls down. It will crank with no problems put never fire. Today I put a jumper on one of the glow plug relays and watched the voltage. It pulled down as I acspected.
I tried to start it and it fired a couple time but it wasnt having it cuz the other bank of the motor didnt have the glow plugs on a I assume.
Could someone tell me what controls the GP relays.
Or, is there any advice on where I should start.
Ive gave up and come back 5 min. later just to try it and they start working again and it fires up with no problem.
