Did you ever run completely out of gas before the first failure?

Not in the 3 months that we've owned. It has about 65000 miles on it, so I'm not suprised the pump went bad. The truck had been in a major collision though which lead to it being in the repair shop for quite a few months.

That's got to be a fuel pump, fuel pressure regulator, or fuel pump relay problem. You need to check fuel pressure at the fuel rail for starters.

MPG's by jl49

I bought a 2007 Jeep Compass just recently. I'm getting around 14 to 15 mpg's which is not the 23 to 26 mpg's advertised on the window sticker. Dealer claims it's the oil companies putting more ethanol in gas which is lowering the mpg's. What can I do?

Nothing you can do except attempt to drive differently (try the various hybrid forum "driving tips & tricks" to see some examples of what you can do to get better MPG).
 
The dealer sticker is only meant to be an indicator as a comparison to what other vehicles (in the same class) get for MPG. The fact that the figures are not a guarantee is stated in the fine print at the bottom of the sticker. There is no legal guarantee that you will achieve any particular MPG.
 
If you can demonstrate that the engine is not running correctly you could have that repaired, but if an engine diagnostic does not show any errors it would be difficult to prove anything was wrong.
 
You can't invoke the lemon laws over MPG...
 
Jeeps are notorious (in my limited experience) for lower MPG. Excellent off-road capability though.

And the testing method was very inaccurate. The testing has finally been revamped starting with 2008 model cars so they should be more accurate now.

buick century problems by jdh93

I have a 93 6 cyl with 70,000 mi. About 3 weeks ago the muffler and tailpipe which were already rusted out fell off. The cat converter is still in place. It ran fine after this for about a week, then it went completely dead. The starter was replaced and it ran fine for a few days. Then it started dying after it started and smelling of gas. After waiting for a while, it eventually starts, but only after releasing a plume of smoke. It then runs and idles very sluggishly and at times dies again.I have to start it and immediatley put it in gear and go or it dies. This happens about half of the time. The other half of the time, it starts on the first crank and runs and idles smoothly. I have replaced the filters, spark plugs and treated the injectors and fuel system. Various mechanics have looked at it and none claims to have seen the problem. When it is plugged in to the computer, no codes show up. Can anybody help me???
Thanks

Have you put a replacement exhaust system on it, and have they also replaced the 2nd Oxygen sensor (the one after the catalytic converter).
