Replaced timing belt and accesories. When I was done and tried to start car it will crank beauitfuly but wont start. Tested and it is not getting any spark at the plugs. Suspect I damaged the Crank position sensor. When I test resistance I get between 499 and 500. What should I be reading? I searched internet and found one site that said between 520-580 and another that said between 950 and 1250. Please help! If not CPS then what else could it be?
