Check the spark, I bet it's gone again......

Stupid immobiliser system will have you chasing your tail. Sometimes it cuts injectors & spark, sometimes just injectors. grrrr.

Yes the immobiliser is probably your problem, have you got a spare key to try. They are the most common fault.

Alternatively, try tow starting, some Hyundai's have a fail-safe, in the event of vehicle speed during running, it defaults to mobilised.

Sorry, I need to elaborate on tow starting.
With Ignition on position 1. Start towing vehicle (at around 20mph), then turn to position 2 whilst moving.
Pop into gear and release clutch.

thanks tony it was a mobiliser got the customer to bring is spear key and it started stright away thanks for your help tony
