1993 Ford Mustang 4 cylinder.... Car has been sitting but my son is about to start driving so we started working on it together. It wouldn't start so we fired it up using a very small shot of starting fluid. It fired right up & ran for about a second, fuel pump never came on. So we changed fuel pump & filter. Pump comes on with key & builds pressure and stops as it should. We have fuel at fuel rail but car doesn't start.

I checked injector 1&2 for power & ground signal but both wires show...

Injector help needed
