how do you know no SPARK?
Did you check a plug and crank it over?

Any codes?

No codes come up and checked it with spark plug tester

Did you check all sparkplugs? If yes:
1) Check ignition fuses (I think 15A),
2) Check the ground wire from both coil pucks (back of the cylinder head).
3) Check wiring harnesses and plugs for damage.
4) Check PCM plug for corrosion.
