intermitant starting fault

[adam v]

Hi All, my name is Adam and i own a auII forte sedan, it is a soild family car and tows the van well but i m haveing some trouble with and intermitant sarting fault.The car is dual fuel.

Fault - when i turn on the ignition the smart shield hand comes on if it goes out the car starts but idels roughly then it settels down and runs a treat. If the smart shield does not go out but flashes there is nothing when i turn the key to start. If this happens i put the car in N rock it back and forward and the smart shield hand stops flashing - that car starts as above.

What have i had done so far -

replaced the N safety switch (not sure if that is the tech term)tells the car it is in P or N

Replaced the control module (controls the electronics so i was told)

Fuel system clean and service.

In addition in the past 6 months i have had the radiator,power steering pump, alternator replaced.

I am at my wits end with the car and i would love to here from anyone with the same issue or possible soultion. As you can proberbly tell i am not very tech savy with cars is if you can keep it simple that would be great.

Thanks Adam
