Sounds to me like your timing is off for some reason... Or the spark plug wires are installed wrong.

Could use more info.

Was it running before and all of a sudden doesn't run?

When you say plugs are "sparking but no fire" do you mean you're getting spark when you crank it but the engine is not starting?

Like Lockdoc says timing could have jumped (worn timing chain) or plug wires not installed right.
