Thanks all for the replies, i asked the tuner he said it should run fine.

So something dwefinately wrong.

@ Roscco, originally put 1000cc and scaled as per the tuner, it would start and i check the plugs, they were COVERED in fuel.

Since then i installed the standard size and it starts( thought it hard to start, takes a few goes with pedal on gas)

my thoughts, I've installed the original injectors incorrectly (standard injectors) or the plugs are fouled badly. i.e they need to be replaced.

What do you think?
