When it's about 30 degrees F or lower my 5.7 will crank but not start, above 30 below 40 If I do get it to start it will pitter out for a few cranks, and then might finally grab on spit a little and then run perfect and super strong, no rough idle and no performance issues.
Has new starter, new battery, new alternator, new fuel pump relay and I can hear the fuel pump running. Haven't checked pressure yet but am assuming it's good considering how it runs after starting.
Am thinking either fuel pressure regulator or spark plugs but am not sure and would like second opinions.
