  • R32 gtr hard start up!?

    Need help on tying to figure out why r32 gtr would start up and crank up fine on a cold start in he morning and the after driven for about 10 to 15 mins, and has trouble starting when warmed up and have to give it a little bit of gas to start it up sometimes!? Any ideas
    Leaky injectors ?
    Igniter!?
    Plugs !?
    I knows it's fuel related so trying to narrow things down
    Anyone ever had this problem before!?
    Thanks in advance

    Sounds like igniton module is on the way out, as it usually plays up after 10 mins of driving. Sometimes if let ignition module cool down for while (10 minutes or more), engine should start normally (not guaranteed that it will, but should).

    If engine did it when hot, cold, would say CAS is on the way out (CAS error code on ECU). It's usually due to age (bearings inside CAS fail and need to be replaced).

    Sometimes hard start can be due to too thick oil or battery is on the way out.

    From what I understand, leaking injector should make engine run rough at idle.

      So from What I understand it should be the ignition module not the cas!?
      Your saying if it was doing it on cold start and warm starts it would be he CAS
      But since only. Warm starts its the ignition module!?

            what EMS?

            Could be a million things since the car has been modified. Shitty warm start map. Ignition issues as said above. (coils, ignitor) Leaky fuel injectors. Bad coolant temp sensor.

              I guess I might start off with the igniter and borrow someone's igniter and swap it for the day! And see if it still does it

                Update

                Switch the igniter with another working condition from monkey nutz and it's still doing the same issue!

                      what ecu are you running? if your going to get a tune in the lowermainland no doubt go to rg and have either tommy or mark tune you. i really hope your not running a stock ecu with 1000cc squirters and a big single...
