Does it have injector pulse?
Does it have power to one side of the coil when the key is first turned on?

How about the injector pulse?

I would highly suspect the Crankshaft position sensor. The EEC relay is powering up for initial prime but not coming back on likely because it's not seeing a tach signal.

Then your going to have to get into some in depth troubleshooting with a scan tool to determine just what is dropping out and whether that crank signal is being read by the computer.
