I do have an online version of the service manual, it's been helpful since the Haynes manual for the Echo is out of print.

If by resistor you meant the relay, no it wouldn't. It's a normally closed relay mounted in the power supply wire to the injectors. The computer doesn't monitor that wire from what I can tell. That's why I chose that location. If it is the cause, the only way I can see it could cause the problem would be that the contacts didn't close properly causing too much voltage drop to run properly, but enough to allow it to start. That's a bit of a long shot, but it's running just fine now so until it fails again, there's not much more I can do other than prepare for further testing.
