Hyundai Matrix 2004 diesel. Sometimes, ignition is ok and on, but no power and black smoke from exhaust.It has only happened on start up, not when driving.There are no indications on the dashboard screen that something is malfunctioning. When I had fuel pump trouble, it did show up on one of the icons, so the mechanic knew what was wrong then. No indication on this problem.
Please close my qustion and reverse my charges.
