It has no spark to coilWe need more information, and you're gonna need to do some more diagnosis on your end.. Theres no way I can hook up my scanner through the internets.
How do you know you dont have spark?
Why did you replace the coil?
Did you replace the plugs & wires?
Have you scanned it? Check for RPM reference on the datastream. That'll confirm the commonly bad crank sensor.
Perhaps the module (right next to the coil) is bad?
Have you checked for 12v power at the coil?
What prompted you to replace the coil, cap, and rotor?
