difficult cold start CRD 3.0

Recently, my 2007 Commander with the CRD motor has become hard to start. Wait for the ore heat symbol to go out, turn the key and it cranks, but no fire. I may do this 2 or 4 or 5 times, until it starts. After it runs as little a 2 minutes, it starts immediately when you crank it. Any thoughts? thanks,

Try turning the key to on, wait a minute, turn the key off. Turn the key back on, wait for the glow plug light to go off, then try starting.

Glow plug issues would throw a code, may not cause the check engine light to come on. If your GP modulator was bad it would make it harder to start. Mine when bad making it hard to start... but not quite that hard.

Got any codes?

As long time driver or German diesel, including MB, I'm nearly 100$ confident it's your glow plugs.

Have you checked for codes with a scan tool or OBD-II dongle/app on your phone or tablet? As mentioned, you can have stored codes with no check engine light showing.

I'm not arguing, I'm just explaining why my position is correct.

I had that same issue and it was the fuel pressure solenoid regulator on the high pressure fuel pump. It had no code. It was 30 seconds to replace as it only was 3 screws and the wire.

What was happening is it would loose pressure very slowly over night, and once it was started even if cold it would start again since the pressure was back up high.
