97 FORD EXPLORER WONT START. CRANKES FINE BUT PRODUCES NO SPARK. CHANGED COIL PACK ANY IDEAS?
THIS IS AN INTERMITTENT PROBLEM THAT HAS HAPPEND 3 TIMES OVER THE PAST 4 MTHS. FIRST TWO TIMES I TRIED CRANKING A FEW TIMES LEFT THE TUCK FOR ABOUT 20 MIN AND TRIED AGAIN AND FIRED UP. THIS TIME THAT DIDNT WORK. HAS NO SPARK. FUEL IS PUMPING. TIMING BELT NOT BROKE. AND COIL PACK IS NEW.
