Stopped by a fellow members house to look at his 300D 2.5 turbo that will not start. Glow plug light won't come on.

Checked the glow plugs, 3 come up as like 70-90ohms. 2 are open circuits. So it sounds like a full set of glow plugs are in order at a minimum.

He put a brand new battery in it because the old one was getting weak. Car turns over really strong but it will not start. It was 48* yesterday, I figured the car would hit eventually but it never did.

Stop lever jumps up when you key the car on, fresh filters, tank is full of fresh (i.e. winter blend diesel), and it drove to the parking spot.

I verified we were getting fuel at all 5 injectors.

Does anyone else's car no start at 48* without glow plugs? Car has around 200k and runs very well when it is running.

I know the red flag number 1 is potentially 5 bad glow plugs, but I still think it should have started without them yesterday.

Any thoughts?

This happens to coincide with him removing a radio from the car, diesels don't have immobilizers do they? If its turning over and mechanically injecting fuel I wouldn't think anything electronic could stop it from starting.
