Right now, you do have spark at the plugs? Any applicable trouble codes? If the computer doesn't see an rpm signal, there won't be an injector pulse. The purple wire with white tracer carries the rpm signal from ignition module to computer, no signal no injector pulse.
For distributor, the rpm signal comes from the pickup coil to ignition module to computer. If there was a problem that caused the old ecm to go bad, if you didn't fix it, it may cause problems with the new ecm?
