Where to start? I drove a 91 kade 5 speed home. And had a 89 Kae auto at home that is in great shape but the single cam motor is blown. Took the de out and put it ,the harness , and ecu in the 89 , yes to the automatic. Will not run!!! Repinned my pigtail on the harness, I do have fuel to the injectors, no injectors , no spark. I have added extra grounds and have checked everything that I know. Help would be appreciated. Any ideas on what I missed. Car cranks but will not start. Thank you

Have you tried tracing the wires back?
And just to clarify, you put in the '91 ecu into the car right?

Yes, the 91 ECU is in. Traced harness wires (each one) all the way back to ecu.I have a feeling my distributor went bad during the swap. Is there a way to test the 4 wires on the dizzy to make sure my dizzy is working. I want to put it into another car to test but I don't know anyone local with a Kade. Thanks

There isn't a way to check out the distributor as far as I know.
Are there any junkyards in your area?

Okay , bought new dizzy, installed, still nothing. Not gonna let it beat me! I noticed today that when i took the 24e ecu and harness out there were a cluster of wires on a seperate plug that run up along the passenger fender well. Having done my under dash repin already, these wires at this plug arent going to anything. Plug sits right above ecu and does not have a home(may not need to go anywhere). I have done everything that i know and still nothing. If you can help I will personally fly to your home town and buy you a steak dinner.
