if you use a rubber hoes to hold the plugs to put them in helps. torque specs Glow plugs: 124 inch pounds or 14NM

Hey bigbubba,
Try plugging the block heater in over night. This may work to help you out until you can change the plugs.
It makes a world of difference for me during the cooler months, even in TN.

A hot relay would indicate that the contacts are burned. This causes a voltage drop across the relay and the additional current draw creates the heat.

Anything between .2 ohms and 2 ohms is good.

ok since the gp tested good im going to try and replace the relay and see what that does. idk if altitude would effect starting or not it normally started just fine in missouri down to between 0 and 30 and im running 15w-40 rotella. and it gets down to between 50-70 at night and if i do not cycle the gp twice it will just crank but if i cycle them twice it fires right up.

well i went out this morning to start my truck and it wouldnt start just cranked and white smoked out neighbor hood. so i jumped the glow plug relay with a pair of pliers and finally got it started went to oriellys and got the gpr-109 and figured i would replace it since it looked like it had been hot and was the cheapest to try first so i started to take the old one off and all the terminals broke out of the old relay and the relay split in half so im guessing it was bad. im hoping it fixed it and i do not have any problems in the morning i would hate to be late the first day of school lol.
