I have been doing some searching on here tonight but I haven't found exactly what I am looking for. In short my truck is extremely hard to start when the temps drop below 20*. I went ahead and checked the voltages at the relay and the relay is working. My inital amp draw on the relay is about 185 amps and it steadily drops down to about 90-95 amps where it finally levels off.
Next I went ahead and did an ohm reading on all of the glow plugs via the connector on top of the heads. This is where my first question comes in. While reading through the many threads on here I have gotten a couple different acceptable ranges for the readings. Some have been saying that .2-2 ohms and others have said .1-2 ohms. Now I know .1-.2 isn't much of a difference but it might be the difference between starting easily or not. So which is it? Is .1 ohm still a good glow plug? I also had two plugs that read 0 ohms so I would assume those are bad too, correct?
I just found out about using a test light to check the glow plugs, but it is really cold out and I don't feel like going out there again. So I will do that tomorrow.
Now I do know that I have at least two glow plugs that are bad (over 2 ohms) so I would really like to just replace all 8 of them since I'm gonna be in there already. I know that everyone is most likely going to say to use the OEM replacements but I do know of one member on here that used a set he got off of
EBAY. Are these ones junk or are they something to consider? I checked on Autozones website and they have the ZD11 listed but there is no price listed and it doesn't say if you can get it in the stores or online. So I'll have to call tomorrow and check on those.
For some reason the link I posted is automatically inserting additional text in the address so it doesn't work. Just copy/paste this address to see the glow plugs I was referring to:

Thanks guys,
