OK I will try to give as much info as possible so maybe someone out there can help. I encountered the problem a few days after a fender bender with an RV, minimal damage, truck drove fine after accident. I replaced the rear taillight, and got the driver side fender straight by removing the lowest bolt and inner plastic fender and bending the panel back. I also replaced a shorted GEM module that was defunct before the accident. Now my ranger won't start but it will turn over, there is fuel pressure at the rail, there is a spark, adding some fuel directly to the throttle body will fire the truck until fuel is burned up. My father is a retired ford mechanic and he plugged his computer into the odbII connector and got no response from my truck. Now I know the machine he has is working because when I bought the truck we used his computer to look at all the sensors while driving and made sure there weren't any codes. I've tried switching relays and cleaning grounds with no avail. I also check fuses and the fuel pump can be heard functioning. Still no start. Does anyone have a clue what my issue could be?
