How many glowplugs can be bad and the truck still start? I got the plugs on the Passenger side changed tonight before it got dark. I only had one bad one on that side. I check them as I pull them out by hooking them directly to the battery with jumper cables. Now I have one better one than before and it still wouldn't start. I had replaced a bad one on this side last year as well and it started like a champ. I put a used one in though, that's why I'm just replacing them all with brand new this year. I'm wondering how many I will find bad on the driver's side tomorrow. I would guess all of them. Also, can anyone tell me the torque on the plugs?

Mine was starting with difficulty but with four bad and one unplugged (three working glow plugs).

CLICK HERE to go to the thread I started when I did mine in October of 2001.

It's not the GPR. I replaced it with a Stan-cor last year when I was having trouble starting and I verified it just to make sure. I also changed a plug on the passenger side at the same time last year because I had the valve cover off anyway. I didn't do the driver's side then. I finished replacing all of my plugs today and it turns out that 5 of them were bad (all four on the driver's side, one on the passenger's side). I have 8 brand new ones in there now so hopefully I'll be ok for a while.

If you had 5 bad GP...your cold starting should improve now with new plugs :thumbsup:
