probably get more respones here. Here's the problem.The last two days my 2001 F350 takes forever to start.Yesterday the truck was in the garage and went to start it up and it just cranks.After about 5 minutes of interminent cranking it starts.WOW,never had that problem before.So last nite I had to leave the truck in the driveway hooked up to the snowmobile trailer as the wife and I were going sledding.It got down to 5 degrees last nite and this morning it took over 20 minutes to start.When the engine was cranking white smoke was billowing out the exhaust.Never seen that before either.So my question is are there some sort of relays that ignite/warm the glow plugs and if there are do you think they need replaced? Or do you think the batteries are weak and not sending enough power to the glow plugs? Again,sorry for putting this in the wrong forum and the long winded post.

We have the same problems with HMMWV's (Humvee's), usually means the glow plugs are burned out.

Only simple way I can think to check would be remove a couple glow plugs, and see if the are swelled up, burned or cracked. If you can swing it It would be a good idea to test the circuit as well. Hopefully it's just a simple fix. Good luck

before you go spending $12-15 each on glow plugs.....(it may be the problem, but may not)......I worked in a diesel performance shop for a few years and usually this problem was associated with the glow plug control relay (module).....it looks like a starter solonoid on top of the engine to the rear/right (pass. side) of your fuel filter......I THINK, the part # is a F81Z-12B533-AC........*lol*.....It's almost midnight and I'm not at work to look it up.........hope this helps ------------------ Without life there could be no music, but without music, there can be no life. 1973 Convertible, 1965 A Code 4spd coupe, Past: 1969 GT, 1967 6cyl coupe, 1968 coupe Two Rivers Ford, Parts Dept., Nashville, TN www.geocities.com/littlewhitecoupe www.geocities.com/jezebeldream www.geocities.com/my73conv www.myspace.com/honeyburst

Thanks for the info everyone...Honeyburst.....I also think it might be the relay or module.Does this 2001 F350 have one or two modules? If I'm not mistaken I think you work at a Ford dealership,right? Do you know what the cost of a module might be or if there is a "test" to pinpoint if the module is faulty before I go spending the money on one.Thank you!!!!

there is a test....cost is around $100 for the part though......your truck only has one gpcm (glow plug control module).....IF you can hold off until tomorrow, I'll ask one of my techs how to test it.........

I think I figured it out.I used a test light and it appeared faulty.Went to NAPA and bought a new module and the truck fired right up. Thanks everyone...
