brandon1996mustang

We believe its either a ground issue or a ecm issue. I need common ground break areas in order to verify if its a ground or ecm. Checked the wires and replaced the coil pack on the drivers side. the left two are still not firing. Checked the spark plug and spark plug wires and they are fine. we took it to get the codes and the were all indications of misfiring...the codes were po351,353,354,304,307. please help.
