I have a 96 ford f-350 7.3 diesel it will run for days and then the next day it will start and loose power it will start with starting fluid and run bad i have changed the fuel filter cleaned the fuel tank and replaced the fuel pump got any suggestions what to try
The most common problem is a bad fuel injector but if you haven't already done so--check to make sure your oil level is all the way up to full.Power Strokes use a high pressure oil pump to operate their injectors and if your oil is at a low level it can cause air pockets in the lines going to the injectors.It's not a real common problem but I 've seen it happen maybe 10 times.Another cause is using the wrong kind of oil.Some oils have a tendency to foam at high pressures and can produce air in those same injector supply lines. Good luck!
