Check the Grounds at the coil mount-----You may find that your coils arent bad --But rahther messing with the bolts during installation is a problem--This is one of hondas pet problems--- Make sure the connections are clean and tight

to the boards

In the manual there is a troubleshooting chart-- and a bunch of specs ---Also--make sure you are using the correct spark plug

[knightrider]

iam already went there!its the right spark plug!

Make sure to stick a new spark plug in when it quits to make sure its not losing spark from a fouled spark plug, then go looking for bad wiring. Dont waste any more money on parts till youve gone through the wiring.

I dont know if it works like it does on cars but get it running and spray water on the wires if it sparks and quits running there your problem.
