Truck will not start, as though theirs is no gas. If I pour a little gas into the fuel injectors, the truck starts immediatly, then dies. Is this the fuel pump?

If so how do I diagnosis if the pumps bad, an electrical problem, fuel filter etc.

Hi scott riley and welcome to 2carpros

When the last time you've replaced the fuel filter? If okay Tee-in at the fuel filter and check the fuel pressure should read 9-13psi
