My glow plugs may not work...

It's a little hard to start, usually on the 2nd crank when cold. I'm in Ga. and the car came from South Fla. so I'm not talking cold here

The dash light doesn't come on at all. Check the glow plug relay box under the hood? Any ideas on where to start?

It runs like a champ when warmed up.

First thing to do is make sure the fuse is good.

Check ohm on plug to know if it is definitely bad. Some will test ok but still not heat correctly. Diesel Giant has pictorial with all of the info.

Thanks for the info! I was all geared up for troubleshooting this and everything started working The glow plug light seems to work properly and it starts much better.

Strange, but my low beam headlights were coming on with the ignition which I thought was odd. Anyway, now the headlights aren't switched by the ignition anymore and the glow plugs seem to have started working...

Bad ground? Bad karma?
