glow plug ohm check

On a 97 f250 diesel what would be a good reading for the ohm check? My truck is having starting problems, and I would like to check the gp's . Smokes at startup, and misses also. Thanks Jcab

I believe if they are lower than .3 you should be fine.

Check your glow plug relay first. They are a heck of a lot easier to replace if thats the case

Even easier is if its a Cali truck. The PCM tests it every time they cycle.
If your GPR has a shunt bar on it. Its a cali and has gp monitor system.
