Just bought a 94 Miata that had been sitting for a while. Previous owner said it would not start so she let it sit. I put a battery in it and it cranks fine but will not fire. Has fuel under pressure to the fuel rail. I gave it a shot of starting fluid and it started and ran for less than a minute. Tach worked, no check engine light. I checked a fuel injector with a noid and it did not flash while cranking. Red/white wire to the injector has 12v with key on. If it starts on starting fluid and I have no injector pulse, what should I check next and what can I eliminate from list of possible problems?
