. It seems to do it after the truck has reached temp. Or got warm. It always starts. But it turns over for about 3-4 sec. Before it fires.I've used several cleaners in the fuel as well as directly into the intake via vacuum. Eg. "SeaFoam", "Gunk", "STP"
When I use the cleaners in the intake, it smokes terribly for about 30 min. Anyone with a home remedy would be greatly appreciated as I cant afford a mechanic.

Check the fuel pressure regulator, sometimes when they pop it adds raw fuel to the engine making them hard start when hot. There should be a vacuum line from it to the intake, see if any fuel is present. If there is fuel in the vacuum line replace the regulator. The reg is mounted on the fuel rail
