But I got new fuel filter, new dizzy rotor, new spark plug, changed fuel pump some time ago, maybe when the fuel and ignition system is in good condition, less likely the fuel type we use will contribute to hard crank?Sometimes when the car is parked on non-level ground, need to crank a few times, but thats irrelevant to the fuel I use...btw, i thought M20 engine dont have knock sensor, so why would the ecu adapt to the fuel octance accrodingly??</blockquote>
