The grounds for the leading and trailing coils are their contact to the frame. Try taking the coils off and making sure the contacts are good metal to metal. After that, are the plugs good (how old?) Likewise, the plug wires. Are the plug wire connections solid at both ends?

i just remembered something my rpm gauge on my cluster stop working the first night it did it. no spark from coils, not plug or plug wires. all fuses are checked

take it to a mechanic

If Chuck's suggestions are still not fixing it, I'd say try checking the coil packs.

sorry but im not scared to touch a rotary.

You said that your rpm gauge didn't work do you mean when it wouldn't fire that the rpm gauge would just stay still?
