Well there is a couple of things that I need to know and a couple of tests that you need to do. First off do you know what the fuel pressure is? I need you to unplug the injectors and check the resistance. Then you will need to pick up a noid light and check to see if there is an injector pulse. These noid lights are available at you local parts stores, you do not need to buy a kit just the one that fits your truck should be about 10 bucks. Once you have the noid light then you plug it into the injector harness and crank it do this on both injector harnesses and let me know what the light does.
