I was havin alot of trouble startin my truck and I figured it was the relay.. I swapped out a new one (GPR109 not the complete stock one) but it still has trouble.. When i bought the truck it would start in 9 degree weather and now its a staggering 25 outside and it *****es and moans to get going.. I dont think its the glow plugs, would the CPS effect this? It doesnt "gallop" when it actually starts though..

I have been having the same troubles and someone told me if you have a chip or a programmer in the 7.3L PSD then it will cause hard starts, whether that is true or not i am not 100% sure.

I'm having the same trouble but I have a couple of weak glow plugs that sooner or later are going to get replaced along with all the rest of them. There is a good write up in the maintenance forum on how to check the glow plug system and its a fairly easy thing to do, you might want to try that if you haven't already. I have seen glow plugs ohm out ok but still not be very good.

I never heard that before. I bought this truck from my brother and he tells me its starting that same now as it was when he had it and like me he thinks glow plugs. He did replace the GPR just before I got iy from him and it didn't help. My glow plugs are original so I know I gotta have a couple of weak ones. I will replace the valve cover gaskets and all UVC wire harness & glow plugs while I am there. I'm just waiting till I have enough cash on hand to cover all the costs in case one gets stuck and I have to pull the cab and pop the heads off. I have a shop with a lift so I just gotta cover parts costs and find the time to do it. I need new up pipes too so I might wait a little longer and order the Inernational pipes and do them then too. Then I start thinking this would be a good time to do a turbo upgrade too.........I really need to find that pot of gold at the end of the rainbow.

Don't throw parts at a problem, do the proper troubleshooting.

Troubleshooting GPR & GP's

If you need GP's only use ones made by Beru.
