2004 Peugeot 407 2.0 HDI won't start when warm.

Post by wfh »

Hi all
I will try to articulate the problem as clearly as possible.
1. Cold start no problems
2. Hot start within 30mins of engine stop (approx) no problems
3. After longer stops must wait 2 to 3 hours before it will start. (turns over endlessly)

Normal start, the Glowplug light flashes on very briefly
No start situation, the Glowplug light turns on intermittently whilst turning over.

I suspect the Coolant Temperature Sensor or the Glowplug relay.

Any thoughts. before I start randomly replacing items, would be appreciated.

Really need to have a look at some live data when the engine is not starting. Engine speed, coolant temp & fuel pressure being the main ones.
