Bit of an interesting one here.
Car starts up first time every time on a freezing cold morning. But if you drive the car and turn the car off for a short period of time it just wont start again. this isnt really an issue most of the time but if you duck into the shops for a minute, you have to wait about 10-15 mins before the car will start up again. Car has only started doing this since all the parts were put on and tuned. plugs have been gapped down to .8 from 1.1, brand new battery (550CCA) .
It cranks and cranks but just doesnt fire. any one have any ideas?
car always started fine with nistune and usual bolt ons. now has Z32, bigger injectors, pump. All of which were brough brand new
anyone care to hazard a guess at what it might be
thanks
