Start up Smoke

[hayjayhorses]

I pulled glow plugs on my '94 a few years ago with 300k miles on it (i do not know if they were originals). I did the "test light" test and all eight made the light, light up bright.

I tested each glow plug with a 12 volt jump box and infrared thermometer 4 or 5 would get to about 200* and the others turned pink just at the tip, a new one will turn red for about on inch.

I think the best way to test is to take a 100 amp amp meter and hold it rite on to of the glow plug relay, connecting the relay studs to the studs on the amp meter and then you will see how many amps the glow plus pull. Use the meter on a new glow plug so you know how many amps 1 plug pulls

Well I just fired her up at 12 below. No problellm starting, but Idon't imagine the neighbors appreciated the diesel cloud. I let her run a couple minutes then shut her off and plugged her in tosee what happens in while. And the old plugs would light for about an inch als.l

I haven't yet tried tuning anything with the air intake heater but I will see if I can't do something with it and get it to turn on once the glow plugs turn off....usually, it's commanded after a couple minutes of idling but if it can be commanded sooner and during warm up, I'll let you know and maybe you can get Bill to incorporate that into your tunes.

But then again, maybe Bill will read this and know the answer already.

I also found out that if I leave it plugged in that it won't smoke on start up. I am thinking maybe averything just might be normal, a COLD diesel. Thanks for everything so far guys. It's nice to have a little help figuring things out sometimes.
