Thanks again Will.

i STUMBLED AND BANGED MY HARD HEAD AGAINST THE CONCRETE WALKWAY ABOUT TWO WEEKS AGO, BUT THANKFULLY, I DID NOT HAVE TO HAVE ANY STITCHES OVER MY RIGHT EYE. FOR ABOUT TWO WEEKAS I COULD HAVE WON THE UGLY CONTEST IF THERE WAS ONE. EVEN WITH GOOD FUEL FLOW IT IS STILL A NO START WITH THE "WAIT TO...

This may be my final post. I have recovered enough to install the new lift pump and new filters with my son's help. We established good fuel flow right on up thru the fuel filter. I have cleared the fault P0381 twice, but it keeps coming back, and the Duramax does not make any effort to start...

My recovery is very, very slow.

my son installed the new lift pump last Saturday but found a leak in the input hose, but it was too cold to continue in the 27 degree temperature. I'll try to cut that part out and reconnect it. With my disgusting handicap, it takes me forever to get anything done.

Thanks a bunch, Will!

Well, I had a ministroke during the night of December 15th, and the recovery is very slow. I have a new lift pump and new filters, but at this point in time, I am not sure when I will get it in. My son has promised to help when he has time. My mobility leaves a lot to be desired. I will post...

Thanks a bunch. I'll try to look at that aspect when I recover a bit from this ministroke.

That sure sounds interesting Big Dog. Happy New Year, and I sure hope that I don't have that kind of luck.

Thanks a bunch Will, and Happy New Year!

I sent the $476.00 lift pump assembly back today.

If we are talking about the engine driven fuel pump that is a real job to even get at. I'll look for the return line when the weather gets a little warmer. We have a beautiful frost this morning.

I hope this is my thread. Anyway, the new pump will not lift the diesel fuel from the floor up to my work bench. I may have time to try this FAST assembly from a higher level today.

The filters look pretty good, but they were so tight that I put a minor dent in both from squeezing them enough to get the necessary grip. If the pump is good, I'll probably just order two new ones.

I have no idea about these specs. I have the lift pump assembly here in my shed now, and finally got the two filters off. I have to go to Ace hardware forenough parts to rig up 12 VDC to run the pump momentarily in diesel fuel to see if it is good or bad. I won't get all this done until next...

The mechanic with his $8,000 said no. My TOPDON scanner only cost about $400. and I am still learning to use it. It shows glow plug problem, but that and the right rear wheel speed sensor DTC should not keep it from starting.

.........never run again?

It won't even start using ether, and it is primed.:drowning:

Words of wisdom: "It is better to have a sense of humor than no sense at all."

I replaced the Glow plug module today, but still have the DTC PO381 with "Wait to start Lamp Control Circuit"
