Did you ever fix this?mine seems to be doing the same,got it warmed up today after trying another accumalator and then turned it off for a few mins,it wouldn't start as usual,normally once it doesn't start you have to bump it and it will go,had a battery pack on it today as the battery is crap,difference today was with someone turning it over and me pushing and cleaning the metering flap with carb cleaner it would start 8/10,its idles perfect and boosts fine and start from cold first turn off the key,have had the starter issue on another rst but this was turning over fine with a battery pack but does need a new battery,the other thing is if a turned if off and start it staright away it seemed to start every time,at the moment its off the road but will be taking it to a tuner in the near futre but as every tuner is miles away I would like to have this issue sorted,also looked to day and the cold start injector is disconnected and the fuel pump also primes fine,any ideas? could this just need a setup?
