Work Truck down... need help.

New member... very impressed with the help, information and guidance given on this site.

My situation; 2002 F-350, 7.3, 100K, on the highway, snow storm, ran very very low on fuel, filled up, back on highway felt a "burp" depressed acceleraor, nothing, lucky I was just at an off-ramp, had next to zero power, engine was clanking... sounded similar to no oil (yet had oil), alot of blue smoke, pulled over in a safe spot, called tow truck. At my warehouse I changed the alternator and battery (previous week I needed a jump and having four other fords, my favorite... another 02, 7.3 with 260K) I thought the alternator was gone. After charging, I started it and the heavy metallic clanking, no power and blue smoke continued. I have read countless posts to no avail, I can only hope it is an injector yet it sounds too severe to be one injector. I am afraid to take it to the dealer without knowing more as they can charge me "worst case scenario" when it might not be. Any help would be greatly appreciated.

Sounds like you blew an injector to me... When i had one of mine stop working i thought it had blown the motor with the amount of noise that it made... Hopfully you didnt blow the tip off of one and damage something els.... Ofcourse i could be COMPLETELY wrong... Someone els will chime in soon... In the mean time Welcome to FTE!

What order did all that happen in? Need a compression test before you do a lot of guessing.


Welcome aboard.

Your injector rails are full of air. Let it run for a few minutes.

I was afraid to let it run as the noise sounds like it's going to seize. What may have caused the inj. rails to become full of air?

Running it super low on fuel and then the pump starts to gulp air.

Running it that low on fuel... Once you get low enough in that big ol tank as your driving the fuel is "sloshing" around... when its low it will pick up a good amount of air.

I pray that does it. I made a point to add "very, very low on fuel" to my description as I read another post that had made mention to this yet was not sure if this pertained to my problem. Tomorrow I'll let it run. Thank you guys very much, I can sleep tonight.

Just to cover all the bases, you are sure you put diesel and not gas in it, right? Believe it or not, it does happen more often than one would think.

What you have described just happened a few weks ago to my biz partners' 02' F250...It was out of fuel and..lots of air (And we too assumed something much worse hapened and completely dismissed "out of fuel")...When I finally got her running again (wasnt easy)...it ran like a locomotive w/ a miss for about 15 minutes till it finally cleared up. Also, his Low Fuel light had just turned on when this occured, I was behind him and noticed blue smoke everytime he would hit the pedal...then it just died like u described to a Tee.

I was gona ask about not mistakingly putting gas in, cause I'm one of the dummies who's done it. All it takes is a sniff of the fuel tank and you'll know.

It sounds like Air in the Rails as well, there was an event here in Severville where the Pilot truck added Diesel to the Gas tanks.
