Having problems with your Cars & Trucks ?
Problem Starting my 2007 Mazda speed six - Cars & Trucks
Hard to answer with no information, need to know firstly do you have the right key for it? did it die on you? did it fail to restart? need to know what conditions lead up to this problem. if you have the key and it doesnt crank at all then it could be a dead battery. if it cranks but no start is it getting spark? if no then check plugs wires coil in that order. if all good possible crankshaft position sensor. if it has spark does it have fuel? if has fuel is it pumping from the fuel pump? if no check fuse. if it is pumping then is there pressure at fuel rail ? if no check filter, if yes then are the injectors putting the fuel in the cylinder? if no check injector pulse. if yes getting fuel to cylinder and spark then your airflow is likely the culprit. so check mass airflow sensor may be dirty or bad OR idle air control valve bad or gummed up(pull and clean or replace) could be clogged catylic converter.
