2006/55 reg dash lights don't flash when cranking. when running after a bump start no warning lights are lit

Expert:  vauxdoc replied 3 years ago.
Thanks for that, this sounds like the crankshaft speed sensor is at fault, this measures the engine speed and throuh the ECU operates the fuel relay.

When bump starting the sensor will have a higher voltage because the starter motor is not being used.

To be sure it would be best to have the engine tested on a diagnostic scanner and the engine speed could be checked when cranking or you could gamble and have the sensor changed, they cost about £30.

I hope this helps, best regards, Vauxdoc.
