The garage have had my car for 3 weeks but are lost, they still cant get the car started.
problem is we changed the head to a stage 2.
then when you try to start the car it goes to fire and then just turns over without a hint of firing up again.

leave for 5 mins and it will do the same.

any ideas?? im getting desperate as i aint had the car for 2 months and the garage are stuck.


Does this normally happen when changing erst heads?
