I have an 1987 RX7 turbo and i got it running and just rebuilt the engine. But now I try to start it and it turns over but doesnt start. I found out that my primary injectors are not opening. I bought new injector pigtails and got a different computer. Now I am not even getting spark from the coils. Please let me know if you know anything. Thanks

 

Start with the simple things first.

1) check fuses! (both the under hood fuses, and the fuses in the panel near the drivers foot, especially the room/motor fuses!)
2) get a DMM and check for voltages at the ECU, there's a good section in the S4 FSM that has what each pin is and what it's value should be

Along the path of doing just those things you'll probably be able to identify where the problem lies, then get back to us with where the problem is and we'll help you out further (if you can't get it yourself)

 

I checked all my fuses and they are all good I think it might be the main relay I did know what else you guys think. Also how would I check the volts to the ecu Please help is my only car

 

Use a DMM. Also, reading the FSM would be a great start to fixing your problems.

 

I check and all my fuses are good an my main relay was good. Was thinking the Alarm don't know how to disable it
