Here we go again. shut my 87 F150 5.0 off when I got to work when it was time to leave no spark from the coil ,same as 3 weeks ago .First thing I did was pull the new dist and replace it nothing,so I pulled out the new coil still nothing ,its getting power to the coil so I would assume the relay is good . Any other ideas .

I assume the ignition module mounted on the side of the distributor was also replaced with new, and not reused, this morning?

The ignition module is always the first thing I suspect in a total no start, no intermittent, condition.

I'm stumped. Unless the NEW distributor you got this morning was also bad. I assume you remembered to plug in all the electrical connections?

There is always talk of a bad ground causing this condition, but I personally have never experienced this condition.
