check that youhave 12v on pin 30 in the distribution box left side front of engine as this supplies the fuel and ecu relays, then check the outputs from both the relays, if the ecu doesn't get it's ignition switched 12v it won't start.
Check spark at plugs
Check connections on temp2 sender and afm
Check connector to ECU (maybe the wind and damp got to it)
Check that air inlet not blocked somewhere (eg birds nest material in cyclone)
Check trigger signals to injectors
Check fuel pump running
Check connections hall sender and isv and idle control unit - try taking the idle out of the system too - a faulty control unit may affect the start up, the ecu is told it's starting by the ignition switch and throttle switch and adjusts accordingly.
help my syncro won´t start!!
