There is no fire to any of the spark plugs. The engine turns over fine. I have replaced the cam sensor and the crank sensor and still no fire to any of the spark plugs. There is fire to the coils but no fire to the spark plugs. Any suggestions? I am hoping the problem is not the computer.
Do you

If you have spark at the coil that mean the spark plugs wires no good
so it a tune up and if the spark not strong enough change the coil
good luck

Thanks for trying to solve this problem. This car does not have spark plug wires coming from the coils so this is not a possible solution. The coils go directly to the spark plugs. I used a test light and determined there is power coming to the coils but the coils are not firing the spark plugs. I suspect the problem is the computer that signals the coils to fire the spark plugs but since the computer is an expensive item I wanted to make sure that is the problem before going to that expense.

so you don t have spark out of the coil

you have power to the coil (are you sure )
pull the coil out and check for spark when cranking
let me know
did you check for injector pulse?
Did you check for codes?
You need to use a scanner let me know if you have access to one
