#138 of 166 Gas Mileage by wisdodge

Aug 21, 2008 (8:08 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 166 7.3 no start by fphilli1

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!!!!

Glow plug relay would be a good start and the CPS is troublesome on these, as you know.

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.

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.

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.

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).

#147 of 166 Researching to buy a new truck! by hi7echredneck

Dec 21, 2009 (12:10 am)

So I've always had old trucks and its finally going to be time for me to buy a new truck this summer (2010) I am currently a college student and I also work for a construction company in the summer and on holidays. When I'm out at school the majority of my driving is in town. About twice a month I make the trip back home about 150 miles and hauling stuff in my 1/4 ton truck over the pass is killing it! The contractor that I work for has a 2002 Chevy 2500HD (gas) and a debris trailer that when loaded up is usually around 10,000lbs. The truck there is beat to hell and I hate driving it. I currently have to switch trucks all the time which is very irritating. After school I intend on getting into the trades and I need a good truck. Being that I'm in school I really don't have a ton of $ for repairs so i need something reliable! I need your guys help deciding. I've read a lot of bad things about the 6.0L in the Fords. But I'm not opposed to a Ford. WHAT BRAND AND ENGINE SIZE WILL BE BEST? I don't want a crew cab or a long bed. Just simple extended cab and short bed. I've been stressing over the differences and I need some opinions from guys that have owned these trucks. THANK YOU ALL!!!
