Re: 5.3 first start wont start
What year is your engine... You will have power at the injector and the PCM will toggle the ground. To check it if you don't have a noide light just put a 194 bulb in the connector.. Just bend the terminals of the bulb straight and put them in the injector connector, just don't spread the connector terminals...
