I can cycle my glow plugs a couple of times and it will crank fine...I've noticed that my oil pressure light stays on a couple of seconds longer than usual. Makes me think the oil is a little to thick and is taking a little longer to get flowing...anybody else got any suggestions???? Had similar problem???

My new-to-me truck just experienced this. A few weeks ago I traded in my 2000 4x4 standard cab F350 PSD for a 2000 4x4 crew cab short bed F350 PSD. I used it about 10 days ago, and did not start it again until yesterday, and it did not want to start, belched some white smoke, and finally turned over on the 3rd try. It's a lot cooler here this week than it was last week (eastern PA), so maybe I bought the truck with a bad glow plug. It has a 3 month 3000 mile warranty, so I will be calling the dealer about it directly...

01-f350 Can anyone explain to me the wiring of the GPR and the IAH relay. I have battery voltage on both of these relay, at both small terminal. Seems that when I do get power on the outlet side of the GPR, only one small terminal on the GPR has power and the other does not at that time. I need to let the engine cool to check the IAH relay. It is quite evident that they do not use a power and normal grounding for the coil of these relays.

Ok, the rempurature around where I live is about 4 degrees celcius in the night now so it's getting colder. it starts with no problem in the morning, the only thing is that when it does fire and start there is a very faint bit of smoke that comes out, it's almost not noticable but I noticed it that last few times when I got my brother to start it and me just standing at the rear to make sure. Is this normal, Idon't know if I would consider this white smoke or what. ... Any info would help, Im just trying to make sure nothing is wrong.

U have to check the GPR and the ITR when the engine had time to sit over night.You have to check the bigger side of both relays,one side will always have 12 volts,even when the truck is off.Its the other side that your interested in.I beleave that the in take heater only comes on at sub zero temps,thats what a tech told me anyway.
First thing in the morning,before starting the truck,get a volt meter and see which side of the rely has no power.Then clip it to that side with no power and one temainal to the - side of the batt.Then turn your key to the on position,then check to see if you have 12 volts on the side that did not have power before.
If you do not have power on the other side,then check the small teminals to see if they have power on both side.If you do have power on both small teminals then your relay is bad.
If you dont have power on both sides then theres a senser that has gone bad.

What causes some blue smoke, thats what I had today when I started it up, it seems to be getting worse everyday now. I never had any smoking problems when I first got this truck in the spring and it was colder then actualy than what it is now.

You'll need a multi meter that can measure ohms. Connect one lead (usually the balck one) to a good ground. Then probe each of the outer pins on the connector. Good glow plugs usually measure between .8 ohms to 1.5 ohms. Some may be outside of that, but won't stray too far. Bad plugs can measure anywhere above 20 ohms, for instance, when I replaced mine, I had three plugs that measured 800 ohms, two that where open or infinite resistance, and one that was around 600 ohms.
I will be installing new GPR unless anyone can think of another test I could do first.
