In my Trueno i have a JDM big port 4age, I recently did and overhaul of all the gaskets in my engine and some cleaning up. But when i put my key in accessory, before cranking it, the igniter,coil and dizzy sound like it arcing pretty loudly, but when i try to crank it just dies.

another thing is when is cranking the rpm in my cluster go all over the place

Anyone had this problem before?

Did you use a pressure washer under the hood ? If you did,
maybe you have some water in the coil or igniter connections ?

Try getting someone to turn the key at night, or in a dark garage,
while you watch the engine electrics. If there is any arcing going
on it is much easier to see sparks when it is dark.
