Thanks for thebquick response. I replaced the ecm about a year ago, but just found out the gloor boars all around the ecm were soaked when it died.. Was running fantastic till the rain.

One last question, that 12 volts goes down to .6 v at the spout when i reconnect the tfi module. Does that matter?

Check the EEC ground at the negative battery post, or body ground near the starter relay. It is important to have a good ground on pin 20,40, and 60 at the pcm.

Most likely a bad TFI module, located on the back of the distributor. If and when it dies you get no spark and of course a no start as a result. They get hot and fail pretty frequently it seems. You can remote mount it if you wish and that seems to keep them from dying....https://www.therangerstation.com/how-to/ignition-charging-computers/remote- mounted-tfi-ignition-module/
