So ive done alot of reading on this site and love it . But this is my first post. I had a can of fuel at home that had been siting around a while but I put it in my 02 F350 with the 7.3. hind site being 20/20 I shouldn't have done that. The truck only made it about 2 miles then started chugging and eventually quit. So I pulled the truck home and this is what I have done so far. I assumed that I had bad fuel so I started with a new fuel filter. I did notice that the fuel in the bowl was a milky white color. Not sure what that means. But the new filter did not help as the truck will not start. So after reading some other posts I decided to drop the fuel tank and clean everything. I did that including cleaning out the 2 screens in the fuel pick up. After re installing the tank I put new clean fuel in the tank and primed the truck. But before starting it I drained the first amount of fuel out of the filter bowl just to make sure I got all of the bad fuel out of the lines. So after doing this I put a new filter in and primed the motor again. I appear to be getting good fuel pressure and the fuel looks very clean now at the bowl. But the truck does not even attempt to start. It turns over just fine but will not start. I am looking for any advice I can get before I have it towed to a shop. Also if it helps the truck currently has 305,000 on it and has run great up till now.
Thanks in advance.

I would do a Fuel pressure test and a engine compression test.

 

I am no LT diesel expert but I have plenty of experience on the large cars so bear with me.

Did you bleed the individual lines to each injector (hopefully this will clear the pump also).

If the cylinders are soaked with the bad fuel, what would have to be done to be able to spin the engine with no compression to clear them, remove the injectors or glow plugs if equipped?

Consider a fuel/water separator. Maybe a can of HEAT to clean the system once running?

 

fuel must be clear from tank to injectors...

bad fuel can clog injectors as well. even with filters.

 

is highly unlikely that there was no water in the bad fuel as a result of condensation.

 

I'm not sure what the milky white is but, as tough as the 7.3L is, bad fuel can spell the end for the installed injectors.

I recommend you re-post in the 1999-2003 7.3L diesel section. Lots of guys way smarter than me can help you out to see if you can get it started.
