   can anyone help me i got a c2 gt engine in a furio and its only running on 2-3 cylinder but is sparking on all 4 but fuel injector is fueling 2-3,
   
   i have tryed the crank sensor but not sure if the c2 has diffrent possitions on the flywheel?

   Injectors always get power if the live isn't broken
   
   
   The engine batch fires on 1&4 and 2&3... so the earth wire for cylinders 1 and 4 must be broken or damaged
   
   As the live is there as soon as the ignition is turned on.. To make them fire fuel the ecu flashes an earth at them to complete the circuit
   
   If the earth is damaged then it won't fire

   C2 engines may batch one 1&3 and 2and 4
   
   I don't know ive not got much experience with them, but I'd have thought they be the same tbh.. Very much doubt they'll be diff

   They run on saxo vts management / inlet / injectors+rail (in a saxo anyway)
   
   So i'd assume they'd spray in same order

   To op - try a different injector loom.
   
   That will be easiest / cheapest thing to try first. If still there - i'd try a different rail/injectors.

   I thought as much.. Just a jp4 In the gt still isn't it?
   
   It will be the injector loom.. If not your gonna have fun tracing the break in the earth through your loom
