This car starts well if very cold or if very hot, but not in between. It is independant of plugs,leads,cap,rotor,coil,the 6 injectors,idle valve,eha,fuel pressure accumulator,fuel computer,temperature sensor. It is helped if the battery is charged off the car to 100%. The starting injector delivers correct amount of fuel and doesn't drip, but could engine vaccuum still suck fuel through it? Once it keeps cranking it will obviously fuel up as can be seen in the exhaust when it finally splutters up to idle after a 10 sec or more rest.
