Is it running rich? Pull plug and check. If so suspect engine coolant temp sensor (2 wire one).

Try a different ECU. Sounds dead.

Have you done a compression test? Remember, JDM means 'japanese junkyard motor', despite whatever the Honda kids might have said.

If the ECU was socketed, is it using the standard EPROM, or an upgraded chip? If it's an upgraded chip, do you have injectors on to match the new fuel maps? If it's the original EPROM, make sure whoever desoldered it didn't damage it, or any traces. Also, if you have a logger/reader, plug it in and take a look at what the ECU thinks is happening.
