Start with the main relay. It was a lemon part those years, leading to intermittent failure to start because it doesn't always turn the fuel pump on.

You may need to replace the ECU then. If it's not the main relay, a few people here have had ECU's that were slow to "boot up". That does the same thing with CEL staying on and fuel pump not starting.
