A hard starting condition may be due to low fuel pressure. Our technicians tell us the powertrain control module (PCM) should energize the fuel pump for 2 seconds when the ignition is turned on in order to properly pressurize the fuel system. Correcting this condition may require updating the PCM software.

Takes at least 2 tries before it will finally crank. Often it can take up to 5 or 6 times before the engine fires up.
