try jumping it.
your batt may be strong enough to turn the starter, but not strong enough to drive the FI & ignition electronics.

distributor cap...Maybe if you have a hairline crack, enough moisture has seeped in (sort of the same effect as a car wash)...Might check coil as well. Best of luck.

The cap screws push DOWN, then turn, release...the spring tension holds it on. You might have a crack that you can't see. Was the inside of the cap dry? How did the contacts look (rotor contact as well)? Were they shiny?

Can you hear your DME relay clicking on? Stage I should come on in the relay with the ignition key to "on" position.

Stage II on the DME relay powers the fuel pump. The computer needs to see the crank position moving before it lights the fuel pump. Is your fuel pump coming on or getting power during cranking - use a test light?

I'd make sure you get power at the DME relay (that turns on the computer). From there, the computer will turn on the fuel pump, injectors and time spark. I think if you have no spark only, it could be bad grounds, bad coil, no rotor in the distributor, OR??
