Turbo Desirous
So I should start by saying I just got this truck recently, and I don't know much about it other than the original owner took good care of it (maintenance records) but the person who owned it before me was a complete idiot.
That being said...
I am having the most frustrating issue with the glowplug system and it makes no sense to me... I can tell the glowplug controller was replaced recently, all new glowplugs, new glowplug relay, and yet it just does the afterglow when I turn the key on (although not consistently). All glowplugs read 0.4-0.5 ohms. All glowplugs are getting nominal system voltage (12-12.5) if I manually activate the relay. Batteries are good. All the wiring is hooked up correctly and the controller has a good ground.
Even if I manually activate the glowplug relay the glowplugs apparently still won't glow, even after a minute and a half the truck still makes no hint of firing. Plugging in the block heater, or heating the intake with a propane torch will start it just fine, so it's not a fuel issue.
Am I wrong in concluding that the glowplugs are to blame? I'm just find it hard to believe that 8 brand new plugs wouldn't be glowing with 12v applied, even if they aren't Berus they should still glow, ya know.. I have no clue what brand they are as the P/O installed them. It's getting new GPs shortly anyways as I'd be surprised if they are Beru's. All but one of the connectors are OEM and they all make good contact so I'm at a bit of a loss as nothing appears to be WRONG.
I never had this much trouble with my '90 IDI even with a couple of bad GPs.
Insight is appreciated!
