After several long weeks of startin up easy in the mornings and truck sitting 9hrs during the day and startin hard after work "Finally came across a post that fit my problems to a T". In the 45 min drive to work- couldn't get any better, after work- roll over up to 20-25 seconds " it seemed" then she would fire up- middle real rough and stink/smoke as if it was flooded. After those starts I would have to let it warm up like the old cold natured carbureted 350's. A mechanic I am not but a do it ur selfer I am. 1 fuel pump, fuel filter, carbon vent purge value kit, plugs, wires and countless hrs of cussing and working till the birds start churpin: A $50 fuel pressure regulator 5 min job solved all my headache's!!!! Hell yeah!!!! Thanks to All that takes the time to post their problems and fixes!!!!! Gonna refer to this site for all future problems!!!!!!!
