Just replaced strip fuse and it cracked in half when I attempted to start the car! I tested voltage on battery and it is 12.54. Tested voltage inside glow plug relay - it is around 12.47 volts tested voltage on powered side of strip fuse and get 12.47 obvoiusly I get zero on other side since it is cracked. Also tested resistance with multimeter turned on and set at 200ohm - it reads 0.6 by itself (meter won't zero out) Tested #1 glow plug relay wire and got 0L ohms (what does 0L mean? - i assume that means zero), Tested #2 and got 0.9 ohm need 0.6 deduction thus 0.3 Tested #3 glow plug relay wire and got 1 ohm - 0.6 = 0.4 ohms Tested #4 and got 0.9 ohm reading - 0.6 = 0.3 ohm and tested #5 and got 1.0 ohm - 0.6 = 0.4 ohms Need to get a strip fuse from dealer - I think they are 30 amp (let me know if that is correct) Okay now what does all this mean? Is #1 my problem area? Also when I go to start it , car cranks fine but glow plug light in the instrument cluster does not come on. Getting late will check glow plugs tomorrow.

You've posted in the parts for sale forum. The Diesel Discussion forum is where you want to ask this question.

That being said, you need to replace the strip fuse. It is an 80 amp fuse.
