I think spooled up is on the right track. get a volt meter and check the amperage, also try checking your MFR. mine was on its way out when i was getting that error code. also check your fuses. after i swaped it out, it turns out that to fuses blew and wouldn't start. GL, hope you find it.

my fuel pressure is good i chnged the regulator im thinking it might be a mixture of distributor going bad and a faulty o2 sensor

spark plugs, wires? make sure the rotor is screwed in, don't forget to check that main fuel relay.
