My truck takes about 3-4 times to start. Is that the fuel pump or what?

I have the same problem and have trouble codes 35 and 36. I found out that there is a computer module that needs replaced as it sits low in a valley and gets hot and seperates. I am reseaching about the a/m fix that installs the new module away from heat.

The fuel sending unit only controls the gas guage not the fuel supply to the vehicle. The pump is twelve volts. If you are not getting twelve volts on the PUMP wires check the fuel pump relay and the key circuit to it. If you have to cycle the key three to four times rapidly to get the vehicle to start check the fuel pump pressure at the regulator for manufacturer specs. An injector stuck open will also cause same problems you are describing.

could be pump and check or replace the fuel filter.

could be alot of things but there are 3 basic principles/requirements for any gasoline engine to start. You need fuel, compression and ignition. Not much you can do about the compression short of having the engine rebuilt so focus on the other two. Fuel includes a good clean air supply (check air filter) and fresh gas (check and replace fuel filter). If the injectors have been already been cleaned, that's about all you can do. Have your spark plugs been replaced? Bad plugs will also cause this problem. The ignition system aslo consists of spark plug wires and other components that may need replacing. If this is beyond your mechanical capability, I'd have a mechanic connect the car to a scope to see if any of these systems are acting up.

Try this. Turn key to the on position, but do not start. Now press accelerator pedal all the way down for say 5 seconds. With pedal still depressed turn key to start position, does engine now start.
