Replying to: alanm311 (Apr 22, 2008 11:46 am) Not sure if this helps any, but did you check the lower belt and tensioner? I just changed the belts (yes, the hidden one on the bottom and behind the serpentine belt) on my 04'-5.3 and had a problem with the bottom tensioner. I didn't find it until I went to replace the serpentine.   Hope it helps,   Rick

Replying to: heath2002 (Aug 23, 2007 5:29 pm) I have an 02' 2500 that does the same thing. Engine dies going down the road, pull over wait 10 seconds engine restarts. Will also crank and crank sometimes when starting and will not start. Wait 10 seconds and it will fire right up. Can anyone help me with this. Have taken it to repair shop and they cannot figure it out.
#20 of 27 130,000 miles taping noise by hicks2281 May 11, 2009 (7:12 am)
Just left the dealership and they are telling me it is a bad lift spring or the cam shaft going bad that the engine would need to be replaced. Said they can put a used engine in it with 62,000 for the same price as to tear down and replace cam and lifters. Anybody else with similar problems? Also just had the oil changed and now the taping noise has stoped. Replies to this message: farthur (Oct 30, 2009 7:02 am)

#23 of 27 Engine Shuts Off by thadlooch Aug 14, 2009 (8:33 am)
Replying to: hbd (Apr 12, 2007 2:07 pm) I have the same problem its been happening for awhile with me i found out that its the ECM fuse it keeps blowing.But with mine my truck doesnt start unless i replace the fuse. From what i been told is that the fuel pump might be going but also been told that it might be the distributor going as well. it actually just shut off me on yesterday but for now i jus keep extra fuses in my truck with me for the time being.

My truck has been running "rough", loss of power, sputtering. Check engine light is on intermitten. I had Auto Zone read the code and it was a mass airflow sensor. I bought a new sensor and it seemed fine, the engine light went out. Today (one day later) my truck wont start. I thought I may have gotten a bad sensor so I got another one. I will try it tomorrow. Just wondering if anyone else has experienced this problem. Thanks!
#25 of 27 Avalanche or Toyota Tundra by chris_4325 Oct 24, 2009 (5:13 pm)
I'm looking for a new car/truck/SUV and here is my dilemma: I like Avalanche’s look, but Tundra’s reliability. Currently I have 1999 Ford F-150, and never had any problems with it. I bought it brand new and now it has 140K miles on it. Once a while I need a pick-up truck, and I’d like to enjoy the nice look of it. The bed in a new F-150’s appears much bigger to what I’m used to and I don’t like it. I like the appearance of Chevy Avalanche, but I’ve read that people are having some problems with it. On the other hand Tundra would be more reliable, but it is rather a typical pick-up truck. I might also add that my teenage sons dream of Avalanche. Can you advise me please which car to choose from, or give me some thoughts to start with? Thanks.
