I have an 88 XJ Chief. 4.0 5 speed. The other night coming home it started to lose power and surge and miss I made it too the drive way then shut it off. How it will not start. I have spark it is blue and strong. I can start it on starting fluid, and I dont smell fuel in the cylinders while Im cranking. The plugs dont get wet either. I don't think that all six of the injectors could have gone bad at the same time. So what sensor could be bad that wouldn't tell the ECM to fire the injectors?
