#39 of 193 2002 GMC Sierra 2500 HD--Rough Cold Start by gmcdriver23 Dec 12, 2007 (4:52 pm)
My truck starts roughly only when it is cold in the morning after it has been parked for 10+ hours. Plugs and wires are new, idle air control new, pcv valve new....any ideas? This has been going on for a long time. Thanks in advance.
#40 of 193 Trouble starting in the cold by markyc71 Jan 17, 2008 (10:42 am)
My 2003 silverado will not start in the cold. My battery keeps getting run down and then I give it a quick jump and and it runs fine. My meter says that the battery is retaining a full charge so that leads me to believe my alternator is fine. Any suggestions. Replies to this message: pipefittterr (Mar 08, 2008 7:01 pm)

Replying to: plus (Mar 25, 2007 10:24 am) Problem maybe fuel pump also have experienced this simular prob with 02' Avalanche. Found that if I pump the gas pedal 1 time before starting it will start 1st or second time always so far, lot of cash to replace rite now, will wait until goes out. Hope that helps

#43 of 193 Sierra Starting Issues by tscw25 Jan 27, 2008 (2:10 pm)
I have an 01 Sierra with 6.0 V-8. Drove it a few miles last week and shut it off. Went back a few hours and it will not start. Does not crank, grind, click, anything. All electrical systems "appear" to be working. Battery is not dead, all fuses and relays in the fuse boxes have been checked. It is as if there is no power at all going to the starter. Any ideas?

#45 of 193 LOSING MY MPG!! '02 Chevy 1500 5.3 by jcruzmc Feb 08, 2008 (10:52 am)
I have a '02 Chevy 1500 5.3 liter with 55k miles. I put on a K&N air filter and tornado about 3 years ago and was consistanty getting 17.5+ mpg. During the last 7 months, mpg has been steadlily, consistantly going down. My last tank was 13.5 mpg for the same kind of driving as usual. The air filter is clean, I replaced the fuel filter, the tire pres is good, the spark plugs were replaced (they were in good condition), and I get no indications (check engine light, eng perform.) that something is wrong. I use premium gas because I found that I got more mpg per dollar by doing so. Also, in the Chilton maint book it says that a bad EGR valve could cause poor mpg. The thing is that my eng doesn't have one even though my VIN # (with a "T" in it) indicates it should (the chevy maint people can't explain it). The decrease in mpg seems to have started when I put on all terrain tires. The psi on these tires are 45 (compared to 35psi stock tires) and they are about the same in diameter. If it were the tires, wouldn't I see the difference instantly and not over time? The Chilton book suggests checking the exhaust and emissions systems. How do I do that? Any other suggestions??
#46 of 193 2000 Chev p/u starting problems by chevyjoe Feb 09, 2008 (3:13 pm)
Own two 2000 Chev pickups. One of them will sometimes start with a "metal clanging" sound, and the battery gauge will be low. Now when it does this, the key will not turn the truck off . . . it finally dies. This noise problem/low charge problem is not happening every time truck is started, but seems to be getting worse.   The other 2000 chev p/u would not start, so bought a new battery, started, but the battery charging gauge is low. Help, pls.
