just installed replacement sigma ecu and fob, changed pin all successfully, makes all the right noises and usual charactistics of the LED on the dash on for 30 seconds, it cranks over but just wont fire, its only been laid up a week, plenty of battery - doesnt even try to fire

sigma manual just suggest pressing button once with ignition at on position, get a quick flash from the red led and still no go

is there something else please can could be stopping it? ive had the battery on and off no difference... so nearly there!

anyone please!!??
