Hi there,
I have hyundai elantra 2012 model. It started hesitating for one day and next day it got worst. After that the car only cranks but not start. Fuel pump is fine, spark is there. But the spark plugs are getting matt black powder very quickly even in minutes. When the spark plugs are cleaned it still cranks for a while and after few minutes it starts bat as soon as I remove my foot form the gas pedal it stops and then again spark plugs are black. The mechanic says its bad ECU and got repaired twice but still it has the same issue. Can any one help? Thanks.......
Well it's getting black that fast it's flooding out so it sounds like a fuel injection problem but of course if the computer doesn't work right that can make the fuel injectors not work right and if the guys tried two of them I don't know what the heck is using I personally only use new computers gambling with used ones or poorly rebuilt ones is often a big mistake
