Make sure you have both spark and fuel pressure. The fuel pump relay drives both
the ign coils and the fuel pump - but it has different sets of contacts
internally to drive each. One can work while the other does not.

You can carefully remove the cover to the fuel pump relay and squeeze the
contactor together to see if you hear the fuel pump run. (key may need to be on)
Be careful not to burn your fingers or short anything out. That would be a bad
thing.

The next major item would be the crank position and speed sensors. The ECU
should complain if these are not working.
