2002 focus svt eng code is 5 car turns over but no start tried starting fluid no good changed coil ,crank sensor, spark plugs, no good is getting spark but not every time need help please
Unfortunately, if you have spark but it won't fire on starting fluid the engine may be out of time. I would pull the valve cover and check the timing next.
Do you have any trouble codes?
