1.6 DOHC wont start hot



  • it is in future plans to have bigger power.



  • standard pump is fine for KLZE, or 1.6 Turbo :wink:
    so unless your going above 200+ I wouldnt bother personally



  • Couple of things i can think of here..

    1; Air fuel mix is rich :
    Insufficiant fuel injection control (correction for fuel control) cts sensor fail
    Fuel injector fuel leakage

    2; Vapor lock :
    Fuel pressure is not held in fuel line when engine has stopped..
    Pressure reg control system malfunction..

    If this problems will be with my car i think it wont start cold also. But when it is cold starting well and going well.



  • today checked resistance of my distributor coil.
    it should be 0,46-0,78 ohm myne showing 3,9 ohm.

    Check your Mazda technical maintence manual and you will find my reply is text book for failing to start when hot bud…i only gave you a brief description as a pointer... :shock:

    Having said that though the coil lead is a good indication there..



  • i checked ignition coil resistance. it is 3.9 ohm when should be 0.48-0.78.
    ir means i need new ignition coil.



  • next…

    :arrow: changed distributor to new.

    car still won't star hot.



  • did you try what admin said with the fuel pump?



  • it is not fuel pump 100%.

    i think it will be starter motor.



  • Oh right so it doesn't even crank! Well that's a good suspect then!
