Hey all,

Im having similar problems to others on this thread. For the last couple of weeks the truck (2003 7.3L f250 4x4) was hard to start in the mornings. Seemed to fall on its face when you got on the gas etc. The problem kept getting worse. It would run rough for 3-5 minutes and then be ok once up to temp.

Yesterday I changed the oil, fuel filter, and air filter to knock out the basics. Then when I went to crank her up she started ok but lots of white smoke and then died. It would take 15 - 20 seconds of cranking to get it to start again. I noticed the tach would sit still for the first 10 seconds or so and then start to climb and the truck would begin to fire. It would die after about 60 seconds of running real real rough. Finnaly got it to stay running and warm up but there was more smoke than normal. I would give it the gas to about 1600-2000RPM but it would not stay there and dump smoke like a mo fo. it would slowly fall down \ blow more smoke die.

Once it got warmed up it would drive ok but ocasionaly barf out some white smoke and loose power. didnt sound quite right either.

I am pretty sure i didnt goof up and put gas in it. the station i go to did just recently change their pumps but it seems like maybe this is a glow plug problem to me.

I am running amsoil.

I took it to the shop this morning because i forgot all about this forum.

I dont want to get taken for a ride by this service center in austin so if anyone could chime in on what they think this could be that would be a great help.

Thanks in advance

I've got the bad glow plug symptoms. Should I replace them all while I'm at it, or just the one(s) that are bad? Just wondering what the concensus is on that.

Not sure what your issue is here. You should be reading all voltages in the GPR test as positive with respect to ground. /ubbthreads/images/graemlins/shrug.gif

Welcome to TheDieselStop /ubbthreads/images/graemlins/smile.gif

suvdrivr, I'd replace them all as long as you're in there.

Not sure. I know I had one unplugged /ubbthreads/images/graemlins/blush.gif for quite a while, and had no issues except a little more smoke on startup.

I have also started my truck at 6F with no working gp's or block heat. Took 20 minutes and filled the neighborhood with smoke. /ubbthreads/images/graemlins/phoney.gif

Someone else may have some more info for you.

I talked with my couzin who is a mechanic, and he said sometimes they can be difficult to start with one or two bad, I currently have 3 that I believe are bad and I used a Fluke meter so I am pretty sure my readings are accurate, if I have run it every day it starts ok, but if it sets for a couple of days in the cold it doesn't want to start, if I plug it in it starts fine. I have just under 160K on it and I think I am going to replace all the glow plugs anyway, I just put a GPR on it last week, and the other morning when I was trying to get it to start, I jumped the terminals on the old GPR to make sure that it was getting juice, but it did not help. I am sure that 3 are bad, and I question 2 of the others, I only had 2 that had what I would call perfect readings.
Thanks for your help

What is the part located next to the GPR which looks like it?

That would be the Intake Air Heater Relay. Controls the IAH to reduce smoke on extended cold temperature idle.

I have a "California" 1999 F-350 with 196,600 miles. I changed injector #3 and installed new Bosch glow plugs on that side while I was there. Following that the SES light came on and I pulled code po1395. I then changed the glow plug controller (Napa GPR 110) (cleaned and lubed all connections), check all wiring and connectors. The SES light and po1395 came up following each time I erased the code.

Yesterday, I pulled the valve cover and checked the ressitance of each of the four glow plugs, valve cover wiring harness, wiring from valve cover harness to controller, and the controller itself. All were within the specs that I found on this site. The SES light came on again with code po1395.

I parked the truck outside and it fired right up this morning (23 degrees F) with no difficulty or smoke.

I must be missing something simple. Thanks in advance for any help you might have.

Alpine, our "CA" trucks DO have a Glow Plug Controller, but not the Glow Plug Relay...The Controller looks like a small box with heat fins on top and 2 plugs that plug into it. Its located behind the first relay that you replaced. I'm trying to find a way to test the GPC as well...

Do the glow plugs only function when the motor is being started, or do they play a part on how the motor runs long after its running?

They are only a starting aid. Depending on temperatures, they may stay on for up to 2 minutes.

If you have 2 relays behind the fuel filter, then the GPR 110 or GPR 109 (much cheaper will work).

If you have only 1 relay and an aluminum box with cooling fins on it, then you have a Glow Plug Controller and will need to buy that, if it's truly the controller gone bad.

I think that the Excursions had the GP Controller instead of a GPR.

He has a 2000 X just like Jeff did in <font color="red"> THIS THREAD</font>. I think those with the GPC were some Ca vehicles and some X's, but maybe not all. About the only way to tell is to actually look ... heck, we might even have the second confirmed sighting of a GPR "buss bar" in the wild ... /ubbthreads/images/graemlins/grin.gif

At any rate he might want to read thru that thread /ubbthreads/images/graemlins/smile.gif

I'm going to lock this thread, because it's getting pretty cumbersome.

If you read the info in here and still have a problem, please make a new post, and we'll address your specific problem.

For next season, I'm planning on consolidating the info here in a new, revised FAQ type post.
