Check engine light came on while driving. Everything seemed fine, ran fine, gauges good, but when I turned the engine off I could not get it to start again. It cranks over and seems like it wants to catch at first but then just continues to turn. Its a 98 4.0. CPS is 14mos old, checked fuel pressure at the rail and is good. I could really use some help, just got it out of the shop for a big brake job and dont have cash for another mechanic trip.
