This is one of two main problems. There is an erratic connection on your electronic fuel injection line, the computer box connection to earth or on the main plug, or one of the sensors on the engine is starting to play up, as itself within, is connecting erratically, which will eventually break down completely given time.I suggest as a safety measure replace all the three or four sensors on the engine, plus check the airflow meter(If it has one) as it might save you the inconvenience of getting stuck out in the middle of nowhere and the costs incurred in the event of this happening.Most modern day vehicles are designed to start giving some kind of problem after about 100,000 miles or five years (which ever crops up first, and it seems like your model is about to experience this.Just a little reminder that heat is a major cause of electronic breakdown in any application.So therefore contraction and expansion of any working part can mess one around chronically.I hope I have been of help to you. Best of luck.

Sounds like a problem with your catalytic converter or possibly just an o2 sensor. If it is a cat problem I would make sure to have them address it b4 your warranty is up as they are typically very expensive!

It's got all the symptoms of a leak in the fuel line. You may want to start backward at the tank and work your way all the way to the carb to find it but it would be surprising if it was something else. All the best.

SOURCE: Truck just stops b- 2005 Ford F150 80,000 miles

I had the same issue i changed the fuel fillter it was a little dirty but not bad. Still had problem then i cleaned out the throtel it worked good for a while. Ended up replacing the throtel its about $250 if you do it yourself which is not hard to do. The problem is the electronic throtel control but you have to replace the whole thing not sold seperatly hope that helps. Been running great did that 15,000 miles ago.

2008 FORD TRANSIT 2.4L DIESEL BIG END TORQUE SETTINGS

The torque settings for the big end (connecting rod) bolts on a 2008 Ford Transit 2.4L diesel engine are as follows:
  • Step 1: Torque the bolts to 25 Nm (18 lb-ft) using a torque wrench.
  • Step 2: Tighten the bolts an additional 90 degrees (1/4 turn) using a torque angle gauge.
  • Step 3: Tighten the bolts another 90 degrees (1/4 turn) using a torque angle gauge.
Note that these torque settings are for the standard size connecting rod bolts. If your engine has oversized or undersized bolts, you will need to consult the manufacturer's specifications for the correct torque settings.
Also, it's important to use a good quality torque wrench and torque angle gauge to ensure that the bolts are tightened to the correct specifications. Over-tightening or under-tightening the bolts can lead to engine damage or failure.

I have an 2008 F-450 6.4 diesel . Put the truck in neutral to slow down and the engine died. Now the wrench light is on and it won't start .

It should be noted that the ETC - electronic throttle control system includes a warning indicator, wrench warning indicator, on the instrument cluster that illuminates when a concern is present. Concerns are accompanied by diagnostic trouble codes (DTCs) and may also illuminate the malfunction indicator lamp (MIL). (check engine light ) Ford Electronic Throttle Body Failure Diagnosis

Diesel. Reduce power lite turned on. Shut off engine and started back up - lite is off. Can it be driven?

Jerry, Drive to a good shop. So many things can cause reduced power light unfortunately. The first step would be to get the truck hooked up to a scanner/computer and have the computer scanned for trouble codes. One thing that you could try is to drain the water from the water separator that is mounted on the frame under drivers front door. If the PCM picks up on water, power is reduced until water is removed/drained. It could be an exhaust sensor that is reading faulty. Unfortunately from here its impossible to tell you exactly what the fault is because there are just so many engine sensor inputs that could cause your problem. Check the attached links, forums,instruction and guides, Good luck

I hav ea 2008 ford f550 6.4 and my motor just died on me with no warning and now the motor won't turn over and no lights are on

Sounds like a discharged battery. I'd recommend checking charging system. You could have a bad alternator or a broken connection. With luck - the latter.
