I have had my bronco for 4 weeks it ran fine till last week. I was driving it acted like it was running out of gas stopped to put more in it. It didnt start. Pushed it off to the side went back 1 hour later it started. Just to be safe changed the fuel filter. Ran fine for a few more days, went to a few places started it over and over then the last stop went to start and nothing but the auxillary working nothing. thought it was the key so i tried that didnt work looped the selinoid and the starter turned over but didnt start. Changed the selinoid and that wasnt it. Someone told me it could be the actuator? what is that? any suggestions will be appreciated.
