12.7 detroit MAJOR PROBLEM -NEED ASSISTANCE TROUBLESHOOTING

To much ether. Use ether like you gotta pay big bucks for it other wise you crack a ring or a piston then you are screwed.

 

I'd check your fuel pump make sure your getting fuel. Check air filters for restriction, pay attention to your turbo, and start at your batteries check grounds first. Also listen to your starter if it was dragging then stopped you may have a shorting starter.

 

Too much starting fluid will make that noise, sounds like a very bad rod knock. It sounds like you have a fuel problem to me. It could be a power problem to the ECM too. When you turn your key on, does the check engine light come on for a few seconds? If not, check the ECM fuses.

 

That valve stem on the fuel cap sure brings back some memories of chasing leaks in a fuel system. We used to push air back through the return line that way to find a sucking problem

 

Sitting like that, your fuel filter is likely plugged. Or filter(s) as I believe there should be 2 depending on truck model. So no fuel is getting to engine. I know, it ran fine last time. But that is how it works sometimes. Runs, shut it off, filter is plugged enough to not let it start again after cooling and sitting for another month or more.

The run up was ether caused. That is the test book perfect description of too much starting fluid. Any damage done, if any, is permanent and cant be undone without $$$$. Lets hope none has been done.

Charge the batteries, change the fuel filters, plug in a block heater if it has one, and hook up your pickup with jumper cables next time before you try to start it again. Remove the battery cables and have a rat tail file, emery cloth, and a wire brush handy. Get all cable connections clean and shiny. That means the ground too, at all connection sites. Frame, batteries and starter.

If you heat up your starter and run low voltage to it, you risk of sticking the starter on. At that point if you are not prepared for it, you can have a truck fire on your hands.

IMO.

 

I would side with the fuel system sucking air somewhere. I had a sterling this winter die while idling in yard. Would not start. After checking all electrical I decided to check fuel prime. A little spray of brake cleaner (basically either) she started up and ran. If I let it idle it would try and stall unless I kept on the throttle. The problem was a rotted aluminum filter housing sucking air around the fitting threads. Also had a 96 frieght with detroit 60 it sucked air around threads of the fuel tank splitter tee. Look at all your fuel connections if you see any that look damp (does not need to be wet or dripping fuel to suck air) tighten them up and re prime the system.
