2003 F250 6.0 125000miles.....all is well driving down the road, run over something big in road, hear a pop and engine dies, drift off to the side of the road. Now the truck will not start, and I mean will not even turn over or click the starter. Batteries fully charged, electronics in truck work fine, checked for damage to trans shift selector on side of trans and no damage, just will not turn over. I manually engaged the starter and the engine will crank over fine but not start. Borrowed a scanner and cannot communicate with the ECU. Checked and do have power at pin 16 of the ALDL. Tried different scanner and still cannot communicate. Could the ECU have failed from the bigA$$ pothole or is this just coincidental failure? Was running a superchips canned economy tune, have exhaust and intake otherwise stock truck...anything else to check before I try a new computer? Can I buy a computer and just plug it in or do I have to get it programmed to match the truck VIN etc...ANY IDEAS?
