Johann Posted July 19, 2009 Report Share Posted July 19, 2009 Did you check IAT/ECT fuel corrections and such? Quote Link to comment Share on other sites More sharing options...
Thomas Pyk Posted July 20, 2009 Author Report Share Posted July 20, 2009 I have checked this corrections.The car have been working well before and now it fails sometimes to start.When engine runs it runs good and when I stop it.It will not start.

Simon Posted July 21, 2009 Report Share Posted July 21, 2009 What are your trigger settings. Thinking along the lines of the arming voltage being slightly too high at low RPM. Quote Link to comment Share on other sites More sharing options...

ashesman Posted July 22, 2009 Report Share Posted July 22, 2009 Is the ECT reading correctly? Is the post start fueling set up correctly? If it suddenly stopped starting then chances are the problem is a sensor failure or bad wiring connection. Otherwise maybe the temperatures got colder and it wasn't tuned in those areas???

Thomas Pyk Posted July 22, 2009 Author Report Share Posted July 22, 2009 The ECT reading by ECU looks OK due to temprature.Trigger reluctor is new.TPS working OK due ECU , OK , 0-100%.IAT temprature OK.Should check the ECT reading with thermometer.

Thomas Pyk Posted July 28, 2009 Author Report Share Posted July 28, 2009 I got a hint from my dealer, check up trigger signal and cranking speed and found starter motor was worn out,field windings was damage and when starting power was low too electric circuit it could not start, sometimes it started.A new starter motor was installed.The car starts easily now and runs good,even better now.
