Greetings Powerstrokers

[Ralph L]

I've been having cold weather woes with my 2000 F350 psd. Darn thing doesn't want to start below 40 deg F. This is the first Maine winter the rig has seen. Still, I didn't expect to have problems. See, I also have a 2002 psd Excursion. Starts without any complaints even at -15 deg F. So I figured there might be others with cold weather starting problems. Guess what. I found the Powerstroke Diesel Forum. I've been perusing some of the material here and think I'll check the glow plug relay -- today.

I'm not a tech, so I'll give this one a bump and hope somebody smarter than me takes a look and helps you out... But I can say welcome to the forum! Good luck with your problem.

GPR would be my stab at it. I don't know though, hopefully Marc, DJ's or stroke tech will chime in here. I did find this though on a search maybe it will help later?

Ok I have decided to do this write up because I have not seen one anywhere else this was a glow plug change I did on my truck yesterday I took lots of pics so maybe they can help someone else down the road. Im a newb to diesel tech so if I say or have done something wrong please let me know. Cp5899 said this job took him 3 hours it took me around 4 ½ but was not in a hurry what so ever anyways here we go

Here’s where I started right side first looked easy but took longer then the left

After that the intake pipe and inlet turbo pipe w elbow is removed

Remove the rubber piece from the top of the glow plug mine had a yellow wire running out of them break them lose I used a small long pair of needle noses to get the plugs out replace with the good ones torque down to 14ft pounds and when u replace the valve covers they need to be tq to 8 ft pounds.


Here’s what one of the old ones looked like cam out in two pieces

replace it all and move to the next side don’t forget to put the clamps for ure turbo inlet pipe on really good after I finished this good I went for a test drive and when I romped on it a spooled the turbo up in blew the inlet pipe off at the rubber clamp so whoops on my part put in back in made sure it was real tight and it works fine


Ok the left side here’s what u start with

http://img206.imageshack.us/img206/5...ture003im6.jpg

ok ac compressor, turbo inlet pipe and misc wiring has to be removed to get to the valve cover the tensoner for the belt assembly is under the ac compressor I will be two pulleys and u just use a large breaker bar or flat head to take the pressure off the belt thanks trick76cj5 for the quick help with that one

Ok remove the top bolts on the valve cover and I found that it’s a lot easier to take the tire off and reach up inside to break the bottom 3 or 4 off make life a lot easier and quicker

and then replace the plugs the same way u did the other side and down it all back together after I got mine back together I spent 10 min just making sure I didn’t miss anything (missed the lose connection and the turbo pipe whoops) but luckily it was not a problem other then that this is a pretty easy change just takes a lot of time and lots and lots of patience I hope this write will help someone out let me know what u think

Welcome to the Forum, good luck with your woes. There are many people here to help.

You are on the right track. Before you make the jump and buy a gpr test it first. Make sure with the key turned on it energizes. Dont take for granted just cuz it clicks its good cuz it could still be bad. Start with that and we will go from there.

You have some good people helping you out already, sooo

Hope you get it resolved

Thanks for all the support. I did some checking and it looks like the glow plug relay on my 2000 F350 psd is toast - I'm going to do a few more checks to be sure. Part of my troubleshooting included comparing this engine to the engine in my 2002 Excursion; it doesn't have a glow plug relay. Instead it has what looks like a sealed electronic unit. Who know's anything about this?
