I have a check engine light coming on, and it says fuel rail pressure. Some days it may not come on at all, and sometimes maybe once or twice a day. You can stop and turn the ignition off and then back on and it will go off. When the light comes on it will derate power, until you turn the. Key off and then back on. I've changed fuel filter and fuel water separator filter. Anyone have any idea what my problem could be?
