new fuel pumps
fuel filter
fuel pressure regulator
new cap, rotor,wires, plugs, ignition control mod.
all new sensors. map, oxygen,coolant temp sensor
cleaned out the Throttle body any ideas why I still am getting a hard start
its after it sit over night or 8 hours. try to crank and wont catch turn the key off and hit it again and starts fine and if you go to the store or something quick it starts ok, the only thing I can think of is an ecm or injectors any help would be greatly appricated
