I have a 1986 Mazda RX7. I have fuel to the injectors and the car will start but will not keep running. I have check voltage on the fuel pump and the ejectors and the voltage drops to 0 then the key is switched from the start to the run position. Is there a senser somewhere that is turning off the voltage to the fuel to keep the car from running?

Have you checked the fuel pump relay? Is it staying on or shutting off when you go from start to run. If you have a bad fuel pump relay it will shut off the pump.

I don't quite understand what you are saying. You said the relay is working fine the power is not at the relay. So are you saying there is no power at the relay?
