A week ago, I was able to start the engine but it would crank slowly for about 3 or 4 times then it would run fine. I thought it was the starter motor or battery, so I replaced them both.
With a new battery and starter, the engine will not start at all, not even a crank. I hope someone knows the gripe to this...please help
It sounds like you have a ground problem. Have you checked to see that the "new" battery is fully charged? Have you checked to see if the starter motor is getting current when you try to start the truck? Have you checked to see if the battery cables and terminals are corroded, or the cables themselves corroded at any point? You also might have an ignition switch problem due to age or use. You also might have a computer problem that is keeping the circuits from connecting properly. If you have a OBD II scanning tool, it might well tell you exactly where the problem is. Scanners are inexpensive and available almost everywhere. I bought mine through Amazon for less than $25 including shipping.

Check the ignition and Engine relay switches located under the hood. Sometimes relays go weak with age and even a bump on the road will shut them off. If you can turn the truck on, take it to Autozone or similar store for a free DTC scan code.

the only thing that will cause this symptom is the fuel tank sending unit.

My truck did this after I replaced the fuel pump. Turned out to Fuel Pressure Regulator. It would crank and crank but never start. It's located underneath the black plastic manifold on the side of the injectors.

try checking the crank sensor. if a crank sensor goes bad or is damaged it will not allow the plugs to fire but you should still have fuel pressure. also check all connections.
