mobil delvac 1300 super and no on additives ran fine first hundred miles or so and the lighjts on and off its off for now but was on two days straighht

There is NO WAY your check engine light came on because of excessive fuel pressure. Your truck doesn't have a fuel pressure sensor, so the ecm has no way of knowing if the fuel pressure is excessive. What code did you get?

it said no codes check engine light on i took it out and light went off two days later was at the creek went to leave and noticed rough idle about that time check engine light came on and went right back off
