Q: Q: engine cranks over but won't start

asked by on

When turning the key on the engine cranks over but won't start. There is no spark and the tac meter doesn't register any rpm when the motor cranks over. I changed out the crank sensor and the fuel pump assembly and it still does the same thing. It has a coil for each spark plug and they are not sparking. Also after cranking the engine over for a long time, I don't smell any gasoline under the hood. What is wrong?
