What has happened that makes you think the ECU may be bad? I think fuel pump is a more likely candidate than the ECU. I mean the ECU should display some sort of error. Have you put a code scanner on it?

You checked the fuel pressure on the rail?

Clear the codes, then run it a few days, see if the ignition coil comes back. Or just put the old one back on.
