Question about 2008 Ford F 250 Super Duty 4WD
Have a 2008 Ford F250 6.4l- Limp Home Mode problem.Truck would not start after driving to my shop , I tried to start ,then after 4 cranks it went into limp mode. A brief oil light came on then the wrench . After driving 40 miles to another place , it was parked for 4 hours then I started it up to head home. There was no issues, started and drove home 45 miles with no limp mode. I pulled into the driveway stopped the truck then restarted it. limp mode off. Then cranked it over a few times to see if still a problem came back, after 4 more cranks limp mode again. Question, it does not throw a error code or engine light ? Any help? I read a few discussion threads and could be a few things, any help. Local mechanic thought maybe air filter or maf sensor ??

SOURCE: limp home mode
You need to scan for engine trouble codes. Most parts stores will do this for free, and tell you what they mean and make recommendations on what to do. The 'limp mode' kicks in to prevent damage to the vehicle when the computer gets data that something is wrong.. When you shut it off, it's temporarily reset, but then the cars computer is signaling there is still a problem, and it goes back into limp mode. If you have any questions after getting the codes 'read' , post questions and code #;s here for help. Good luck.

i would drain the oil and change it and the oil filter, then i would replace the fuel filter and try to start it if still has an issue, while cranking check for spark, if you have spark and fuel vehicle should run , as far as the code look up trouble codes on google for automotive and it should help you out.

SOURCE: Truck will crank but not
It's very possible you tripped the inertia, or fuel cut of switch when impacting the driveway. Not sure what year your truck, but many of the pick-up have this switch in the right side kick panel. If you have an owners manual, it will tell you the location. There is a button on this switch, which you depress to reset it.

have diagnostic codes checked to see if you have a cam or crank sensor fault. make sure fuel pressure is at the required pressure, just testing to see if you have fuel at the valve is not enough. replace all spark plug wires. if you replaced two then all are just as old and even when they "look good" does not qualify as "they are good". Replace coil pack. start up drive away happy
