Hi I own a 88 Mazda RX7 GXL 13b non turbo. Ok heres whats going on. Gas is comming up to my fuel rail but the injectors are not spraying. I got a new ECU, they still were not spraying. I tested the injectors there not colged. The fuel injector relay is fine. The fuel injector opening circuite realy is also fine. Both were tested. All my fuses are fine. Now I'm lost Ive tried everything. The car turns over when i soak the thing with starting fuid. Also like I said gas is comming up throught the fuel rail but the injectors wont spray. Also the ECU was from an 87 not an 88 but i was told as long as both cars were manual I wouldn't have a problem. Please help I'm out of ideas anything will be of great help.

Thank you
Damian Parker

 

I'd check TPS. Some cars have a flood clear mode when it detects engine starting with the throttle over 75% open or something it'll kill the injectors because it thinks you're trying to unflood it.
