Re: White Smoke at start-up
It sounds like you have glowplug system issues. Start with the glowplug relay. Measure the voltage drop (digital meter leads across the two large terminals on the relay) while the relay is energized (don't go by the wait-to-start light which has nothing to do with the actual state of the relay). Anyrhing more than a 0.5V drop and the relay is bad. If that shows as good then start looking at the glowplugs themselves. On each valvecover connector (there are two per valvecover, top edge front and back ... four total) the outermost pins are for the GP's (inner three are for the injectors). Measure the resistance from the GP pin to ground. Resistance should be from 0.1 to 6 ohms. If those check out good, then the batteries could be losing a bit or even the starter could be going (even though the starter can turn over the engine, just a bit slower can make a big difference! Cheers!
