    Default 4AGE 20v Help! - won't start!

    Car - JDM AE86

    motor - Blacktop 20v AE111

    problem - The car just keeps on kicking over but doesnt want to start. There is spark, though maybe no fuel?

    occurs/started when - Well i took the AE92 Smallport engine out of the car after i owned it for a couple months and decided to take the 20v option. The car was previously running before i decided to do the conversion.
    So basically the 20v is wired up to a Adaptronic loom and ecu, (done by ant) the engine is in, wired up with the JDM loom but i cant get it to start.(just keeps kicking over)

    Some people have suggested the FCOR but i cannot find the FCOR, maybe as the previous owner took out the bigport and went with the smallport option so maybe bypassed it somehow?

    Any help would be appreciated.

    Cheers

    1> Is everything powered up with key on? (ECU, injectors, coilpacks, COR)

    2> Is everything powered up with key in START position? (as above)

    3> can you hear the pump prime for 3 seconds when you turn the key on?

    4> Assuming the pump is audibly priming, is fuel pressure making it to the engine?

    They're the basic checks, beyond that it's best to get a laptop plugged in and check stuff like cranking RPM and sensor values from the ECU's point of view. Just PM me if you need any other help.
