No Spark
 

:(My Son's 2001 Accent has absolutely no spark. I have installed a new crankshaft position sensor and complete new coil pack assembly. Short of the ECM computer, is there anything else I could be missing? I know the +12V is at the coils and I know the new sensor is firing off the crankshaft. Judging by the schematics, the only thing I see left is the wiring from sensor to the ECM or the ECM itself. HELP!

This problem is exactly the same i was experiencing with my 1997 sonata...when it gets warm it cuts out....also pointed to the crank sensor...but what i found is that the crank sensor is a signal given to the power transistor unit which in turn fires the coils...and this unit is mounted on a plate attached to the engine which when heated breaks down the components input signal from the sensor and the computer reads it as the crank sensor itself...replaced unit and walla..
