#138 of 146 Gas Mileage by wisdodge Aug 21, 2008 (7:08 am)
I towed the trailer from Wisconsin to Colorado and back a few weeks ago. I figure I averaged about 10 MPG and I kept my speed about 68 to 70 MPH instead of 75. My brother in-law then towed it out to South Dakota using a Ford F250 diesel that he borrowed. It was a stock truck, no chip or K&N air fileter. He said he only got about 6 MPG and he said he was going about 65 MPH to try and get the best MPG that he could to try and beat my milage.
#139 of 146 7.3 no start by fphilli1 Mar 03, 2009 (9:27 am)
2001 7.3 Excursion no start. It started this morning, hooked up my trailer harness and started fine. After we did some rewireing on the trailer harness it did not start. I unplugged the trailer harness from the truck and it did not start. It cranks good but will not light. I have replaced the CPS last year due to recall. It has never done this before. What fuse or relay should I check. It have fuel and when I turn the key on I can hear the fuel pump/relay run. I have disconnected the battery terminals twice to try and reset the moduel. Help!!!!

Replying to: fphilli1 (Mar 03, 2009 9:27 am) Glow plug relay would be a good start and the CPS is troublesome on these, as you know. Replies to this message: fphilli1 (Mar 04, 2009 1:27 pm) Mr_Shiftright (Mar 04, 2009 2:25 pm)

Replying to: Mr_Shiftright (Mar 03, 2009 9:50 am) Thanks for the reply. It was a 20amp fuse. The fuse circuit was for the cigar lighter and data. The data communication fuse blown will cause a no start. Replies to this message: Mr_Shiftright (Mar 04, 2009 2:25 pm)

Replying to: fphilli1 (Mar 04, 2009 1:27 pm) One wonders why a 20 amp fuse would blow, so this may not be the end of the story but I hope it is for you.
#143 of 146 Primer pump by szewski May 17, 2009 (3:21 pm)
Where is the primer pump located on a 2003 chevy duramax diesel ?? Replies to this message: Mr_Shiftright (May 17, 2009 7:10 pm)

Replying to: szewski (May 17, 2009 3:21 pm) 1. Looks like it's on top of the fuel filter 2. Open the vent valve (small screw) by turning the screw counterclockwise several full turns. 3. Operate the priming pump (pump it up and down with your palm) "> until a small amount of fuel seeps from the vent valve. allow the pump to return upwards between pumps. When fuel is present, the filter is full of fuel and the system should be primed. 4. Close the vent valve. 5. Clean any fuel which accumulated on the fuel filter. 6. Start the engine and allow it to idle for a few minutes. 7. Check the filter for leaks.

Replying to: helpmeporfavor (Nov 04, 2009 1:55 pm) Sounds like detonation damage perhaps, or a massive overheat? Were the glow plugs damaged as well? Did the pistons chunk out (pieces broken off the piston tops).
