Wasn't sure if I should continue my old thread or start a new one .. .thought it would be better to start new one.

I checked my glow plugs today using the tutorial on Dieselgiant. I checked resistance of glow plugs at the relay and also on the glow plugs themselves. They all read about 0.2 Ohms which seems low but it isn't zero and definitely not open. I tried 2 different meters and did a short circuit test for both (ie touching leads together to see what lead resistance is ... so the number 0.2 is compensated for).

Next I tried turning the ignition on (using remote start), it does not attempt to start the engine until the cluster glow plug light goes out ... I shut it off before it tries to crank. Anyway, I can get 12V at each of the pins in the relay box with the plug off.

The other more significant thing I noticed is that my glow plug light (in the cluster) never seems to stay on for more than 5 seconds. I am wondering if this is a glow plug or timer issue.

I am also having super lag issues. I am going to hook up a vacuum/boost gauge to try to figure that out too! Grrr ... starting to annoy me. I did quite a lot of reading up on lag issues like cleaning out ALDA banjo bolt of gunk ... only to find the OM603 doesn't have a banjo. Also read a lot about how to set valves ... only to find OM603 has hydraulic lifters .. guess I need to be smarter about how I search! Thought most of the diesels would be the same! Bad assumption on my part!

Hopefully some more experienced guys can help here.

Thanks!
