Hi my Vivaro will not start when warm. Starts no problem first

Resolved Question:

Hi my Vivaro will not start when warm. Starts no problem first thing. I have put a new starter motor on, no change. I have also put a new crankshaft sensor on. It also cuts out when you put the engine under power. If you flick the key off and on again it runs again.
Hope you can help, tom.

Hello, welcome. My name isXXXXX will do my very best to
assist you with your question.

Are there any type of warning lights coming on?
Customer: replied 3 years ago.
Hi, no lights coming on, no fault codes. Checked injector wires no sign of rubbing from the air box.
Expert:  Mike Kelly replied 3 years ago.
From what you are describing the issue that you are having is consistent with the fuel pump failing and loosing pressure after it gets hot.The next step is to have the fuel pressure checked and monitored as this is a fairly common failure.
