If you have no spark from the coil to the distributor then we need to check voltage at the other two connections of the coil. Sounds like the ECA or battery voltage is not sending the signal.

I suspect there is an issue with the ECA as discussed in the info below.

Review this material and let us know what questions you have and what you find. Thanks
