turning over and cranking is the same thing. if you mean it cranks bout won,t fire up then it could be spark like the coil, module or the pick-up under the rotor button. take the cap and rotor off and check the wires going to the pick-up, they burn off sometimes. or it could be the fuel pump or pump relay too.

Certain sounds like a gasoline pump. To understand for definite the strain wishes to be measured, takes a tool not each person has. It should be within the forty-55lbs variety. If it was a protection problem it might traditionally and run for two seconds. If it had been a relay, it wouldnt even try to run. Take it to a shop. Have it towed by means of a tow truck, also dont attempt your self, if performed incorrectly injury to transmission can occur exchanging a gasoline pump isnt somthing that an everyday joe should attempt these gas pumps are gentle, they're electric and for this reason are cooled via the gas in the tank, most often of thumb i tell people is to no longer let the tank go under 1/4 to make certain theres plenty of gasoline to chill the pump.

Check your coil. Also check the pressure coming from your fuel pump. But pretty sure its the coil
