Hyundai Sonata engine floods with injectors and will not start up

Hi

Can any one give me some advise.

My Hyundai Sonata will not start as too much fuel is being pushed in
by the injetors according to RAC. They managed to get it going a few
months ago by disconnecting the eletrics to injectors, cranking the
engine and then slowly bringing in one injector at a time.

Problem is that they could not find the fuse for the injectors, so had
to manually remove the connector within the engine compartment which
was very tricky.

Its now happended again after 6 months, and RAC are unwilling to spend
the time to start it again for me.

Does anyone know what the fix for this is, or how to remove power form
the injetors to stop the engine from flooding using a fuse rather then
removing the connector block from each injector.

Any help would be great appreciated as I am lost on what to do each
time this happens

Many thanks

Myer

 

What year Sonata?
