1996 F150, 5.0L 5-spd 4x4

Crank no start, ambient temp has no effect

Plug in the diagnostic scanner clear DTC's it starts every time, starts for the rest of the day, runs smooth and strong, the next morning crank no start, repeat

Parts replaced-battery, solenoid, starter, 3-O2 sensors, dist. cap rotor plugs wires, crank shaft position sensor, coolant temp sensor, a/c components, coolant temp sending unit, fuel pressure regulator, ecm (yes it was programmed to the vin), fuel filter, egr solenoid.

Things checked-ground strap from rad support to frame, ground from frame to cab, ground from intake bracket to firewall, ground from battery to inside fender well, all fuses, fuel pressure, there is fire coming from top wire of ignition control module for pip in distributor, disconnect the battery over night has no effect.

 

Can you tell us what codes you need to clear? Need the numbers, thanks.

 

I cleared the DTCs, truck started and drove it all day even started it 8 times with no problem.

 

Start with the basics. Most sensors will not cause a no start condition and when it won't start cold in the morning, the computer is ignoring most of the sensors anyway (open loop ). Spray some starting fluid into the throttle body to see if the engine momentarily starts. If there is no attempt to start, check for spark and go from there.You have to atleast determine what system is malfuntioning, you spent enough money on it already.
Most of the parts you changed won't cause your no start problem. Why you replaced the starter, battery and solenoid when the engine cranks OK is a puzzle to me. As mentioned, check codes and post them.
