Engine won't start when hot
Hello everyone, I drive a Mercedes Vaneo 1600cc gas and petrol of year 2003. It's been some months that after i drive some time, then the engine won't start till it is cooled. I've noticed that the temperature seems higher than usual, but my technique says it is normal, 70° to 90°.
Since then we have tried changing many parts, as crankshaft sensors, starter and other but without any luck.
I have read online different solutions, like Map sensors, battery grounding etc. but I'm quite not sure what to focus on plus I am in lack of patience.
Could somebody please recommend me of an effective sollution? Would be more than appreciated.

Short of using a Mercedes specialist shop you can use a good scanner yourself to retrieve a list of faults - A lot of people recommend iCarsoft scanners... forget about $50 toy-scanners.
Many issues can prevent a Mercedes from starting in various conditions including when warm.
The Electronic Ignition Switch module is known to prevent the ignition key from working on some models...
The wrong step forward would be to replace good-quality OEM parts hoping for miracle...
Check the live fuel rail pressure is
A good starter battery condition is always a necessary 1st line of defense against low-voltage glitches.
