1997 4 runner, dive 500+ miles a week on this truck, now all of a sudden it decides not to start. It cranks but won't start. This year a new fuel filter on the rail and valve cover gaskets, water pump, plugs and timing belt. Figured should just as well do it I so deep in to this motor , this truck has been very reliable at 410567 miles on it. Put a code reader on and no codes found. hummm Mike
