Having issues with the car (99 mustang gt) not wanting to start, have to prime the fuel rail multiple times to get it going and sometimes have to shoot some starting fluid into intake. Thought fuel pump was bad but car will run longer than the amount of starting fluid I used sould burn off so must be getting fuel. Getting p0193 fuel pressure rail sensors code and car dies if I rev the motor to fast. Is this in the pic the fuel pressure sensor? If not what is this and why is it in the fuel line? And could it be my issue? Car sat for a couple years without being run, have replaced gas in tank, fuel filter, oil change, air filter, and spark plugs to rule that out.
