Problems starting

Check for codes and fuel pressure and report back. We need more info. Use this link to find a good shop near you. https://repairpal.com/repair-shops Alex

Fuel pressure MINIMUM is 50 psi when key is turned to the ON position... 49 psi and the engine will not start! ... Easy to test fuel pressure using a test gauge from auto parts store.. The reason the engine eventually starts is each time you crank the engine a little fuel gets injected into the cylinders - just not enough on the first attempt. You might as well figure on removing the truck bed and installing a new fuel pump module. Good luck!
