Was running fine during routine shopping. When my wife came out ofstore the engine would not crank. Fuel is no problem it has new fuelpump. I have replaced crank and cam sensors, also plugged in new ASDrelay to no avail. Changed coil pack. When I check the firing at plugsit hits ONE HEAVY SPARK and NO MORE at each try. Only hit's again afterignition is turned off and then back on. Please respond with anysuggestion.
