If fuel pump is new you should have good pressure before injectors, but check pressure anyway. If pressure is low go back and check for a bad fuel filter between tank and engine and replace. Fuel lines get clogged because of moisture in the lines causing rust. Did you replace the under pump fuel filter? Back to front, if pressure is good , injectors may be the problem. Do a compression test to see if your engine is starting to die. I have only given you an idea of what to look for. You will either have to check yourself ,or have your truck checked by a shop. GOOD LUCK FREIND.
