1987 Chevy Blazer 6 cyl
----------------------------------------------------------------
I TO KNOW WHERE TO START TROUBLSHOOTING , WHEN MY S10 CHEVY BLAZER , WONT START BUT CRANKS OVER . THE TDC CENTER CHECK OUT OKAY ,AND THERES POWER PRESENT AT THE IGNITION COIL CONNECTER ,BUT THERE ANT NO SPARK AT IGNITION COIL WIRE. I REPLACED THE COIL AND THE IGNITION CONTROL MODULE ,WHAT AM I BYPASSING THAT WOULD KEEP MY TRUCK FROM FIRING. ALSO THERE ANT NO FUEL SPRAYING OUT OF THE FUEL INJECTORS, BUT THERE IS POWER AT CONNECTER, AND FUEL PUMPIS WORKING . I DISCONNECTED THE PRESSURE LINE AND CRANKED ENGINE .AND THERE WAS FUEL PUMPING OUT . BUT I THEN DISCONNECTED THE RETURN FUEL LINE AFTER I CONNECTED THE PRESSURE LINE .AND THERE WASNT ANY FUEL COMING OUT OF THE TBI. WHAT DOES HAVE IN RELATION TO MY IGNITION PROBLEM . WHTATS STEPS AND AREAS DO I NEED TO LOOKING INTO . THE TRUCK WAS RUNNING FINE BEFORE IT STOPED RUNNING SO I AM A LITTLE BOGGLED
