My 2001 Hyundai XG300 has 184000km and has caused a lot of problems. I had changed mass air intake sensor, coolant temperature sensor, water pump, timing belt within 2years term. Now the car engin check light is ON and no engin runing. It just cranking. I checked fuel system(pump, pressure)and sparks& wires. After few seconds of cranking, I pulled out the spark plugs and they are wet with gas and show good sparks. Everything looks fine, but no engine running. I got code P1159 and two O2 sensors. Do you have any idea? Will be appreciated.

P1159- Variable Intake Motor Malfunction

Check the fuel pressure with a fuel pressure tester to confirm its within specs, pressure regulator, injector/s and oxygen sensors.

I checked the Hyundai forum and found that malfunction of crankshaft position sensor is the possible cause. I eliminated intake manifold motor because it works only over 3500rpm and nothing to do with no engine starting(catalytic converter too).
