Glow plug sticky cleanup thread

Been lurking for awhile and got a lot of good information off this site. Now I am having the cold start issues with my '96 PSD. It starts fine when it is plugged in, but takes awhile if it isn't. It runs smooth when it does start up so I think the GP's are OK, I did the test light on the GPR and it stays on for about a minute and a half. I did get it to fire after cycling the GP's 4 times at about a minute and a half each time. Is this just going to have to be my ritual or should I check something else? Also, I get white smoke coming from under the hood when cranking it over when it is cold, is that normal?

I still got noticeable smoke with mine on a cold start. Always starts up though. Everything is new except for the VC gaskets. So if your replacing the gp's pry be a good idea to do the vc gaskets too.

2000 7.3 with k&n kit, hypertech programmer set on #2. Hard to start in the cold, 45 or lower. Smokes when trying to start and runs ruff for a few seconds after start. Batteries are good, had them tested, new bat conectors.. Changed the GPR.
I ohmed the pass side and they all read 1.4 or 1.5.
The driver's side all read 0.0, I doubled checked the common and tried again and the same 0.0.
Any suggestions?

Hi there!
New to the forum, read all of this thread...
I have a 2000 that is starting to get hard to start in the morning. It always starts, but recently (as its been colder I guess?) It has been starting and romping (romp romp romp romp) If I hit the gas it smoothes it out but doesnt rev past 1200 or so for a few seconds, and it is slow as hell for a mile or so. It pushes a little white smoke, not excessive. Is this low oil pressure in the HPOP circut, or glow plug related? any help would be appreciated!

I hate the cold.
My truck won't start. Again. SO I drove my $300 1976 RV to work today. I hate the cold.
So I was rereading this post for my next thing to fix on the $14,000 truck (see how I got to work today, above) and I got to thinking... How long should the GRP-109 last? I put one in two years ago (along with glowplugs).
I'll be checking the resistance of GPs, ICP unplug test, fuse #22, block heater, and recharge my new 1000 cca batteries.

I have had this cold start problem for a couple of weeks, but today the truck will not start on a 50 degree morning!
I changed the GPR and had the batteries checked. The truck turns over and catches but will not start. The tach is moving.
I couldnt find the block heater before but I foud what looks like a 120v plug just below the driver's side battery. Is that it?

After plugging in the block heater the truck started with no problem after about two hours. I guess the oil is te problem. I just changed the oil a few weeks ago, and as a rookie I filled it with 15w. I had no idea that the oil could make a difference as far as cold starting.

So, is it the 2 outside pins on each end of the plug, or just 1 on each end?
Thanks again
