Engine starts first time but dies after 2 -3 seconds try again

Customer Question

Engine starts first time but dies after 2 -3 seconds try again just fires and dies then turn the key continuously and it just back fires in the exhaust and inlet Can start the car by turning the key continuously to engage the starter motor and hold the accelerator pedal down and eventually the engine will run. When engine running it runs fine.

Thanks for that, is the engine management (EML) on when running ?
Customer: replied 3 years ago.
Yes it is
Expert:  vauxdoc replied 3 years ago.

OK, in that case the ECU has a fault code stored and will need testing on a diagnostic computer scanner, by the sound of it it will most likely be a faulty crankshaft sensor the code for this is P0335, phone around for a diagnostic test and when the code is revealed the fix should be clear.

I hope this helps, best regards,Customer

fault code stored is lambda sensor.No other codes stored.I have already replaced TDC sensor and cam position sensor
Expert:  vauxdoc replied 3 years ago.
If the engine is backfiring then its either the cam/crank sensor or the valve timing may be out a tooth.
