Killed a Duramax, help

[RRonning1984]

So I was doing maintenance on a Duramax owned by the Wind Farm last night and had to change the fuel filter. Well that went fine but of course now it wont start and I am losing huge money on this truck. How do you get these POS's restarted after changing the fuel filter?

use ether......thats how we do it.....just be smart about it.....roll it over hit it with ether and itll prime its self.....

[RRonning1984]

I dont know. I have heard some bad stuff about using ether on the Duramax!

Don't use ether on a modern diesel engine. Or anything with glow plugs, for that matter.

When I do the fuel filters on my Dmax vans, there is a wire that has to be removed from the fuel filter cover on the frame rail. It will not start again till this is seated perfectly, and free of fuel. If you got this thing soaked with fuel before you installed it, then you need to unplug it, clean it with electronics cleaner, then reinstall.

Or you could have another problem that I am not thinking of. I have had this happen about half the time when I do filters on the dmaxes. No big deal once you know what the problem is.

As far as priming goes, I just cycle the key, like you do on a Ford. I do it about 6 times till the fuel pump quits each time. Seems to have worked for me.

we've used ether on 08's.....it doesnt make a differance what year it is....if it has glow plugs you run the risk of blowing them off....but thats why i said do it while its rolling over....the glow plugs will not be on.....we cycle the engine enough to where the glow plugs dont stay on for more than a second or two then roll it over and shot it with ether.....thats how i did my stroker when i put my stage I's in....every one told me it would take upwards of 20-25min to get it runin....took use 2......

Got told on the D-max forum that the '09's dont have an electric fuel pump and this one has no filter on the frame rail. Have to manually prime it!

Seriously?? weird.. I have '08 LMM's. I figured that they would have the same system as the '08s.

The other thing you could use if you are afraid of ether is gasoline. It's not as harsh as ether, and it isn't as explosive, so your engine will run better on it. It doesn't tend to burn glow plugs as much either.

Soak a rag with gasoline, and hold it up to the intake. Have some one crank it, and it will fire and run on gasoline vapors. You will have to throttle it with the rag closer or further from the intake. Just give it enough to make an idle speed.

That is how I get trucks started after I do injectors, or HPOP or anything like that..
