Replying to: hiscokid (Apr 06, 2008 7:39 pm) I got mine at a local AC Delco supply store, 1/2 price compared to what any dealership wanted. I heard of other people ordering from gmpartsdirect.com for around $260
#200 of 333 ABS problems by mac53 Apr 08, 2008 (6:13 am)
I have a 2000 Sierra 4WD with just over 99000 miles. It has developed a problem with the ABS. At slow speed stops on a dry surface, the ABS kicks on just as the truck comes to a stop. It goes off when I pump the brakes. It doesn't do this on hard stops.

Replying to: mac53 (Apr 08, 2008 6:13 am) My 2000 Silverado had a recall on the ABS sensors. They did pretty much the same thing. Call a dealer and have them check. While you're at it, have them check for recall service on the tailgate cables as well; I had mine snap while standing on it! The bad part is I received the recall notice at least a month before that happened. at myself
#203 of 333 '01 1500HD Fuel Pump Replacement by bigd41 Apr 23, 2008 (9:47 am)
My 2001 1500HD with a 6.0 Liter has been getting harder and harder to start to the point of having to floorboard the pedel to get it to crank. The truck has approx 182k miles. After that it would run Ok but a little rough idle. I thought it was my fuel pump and my mechanic confirmed it. I have been reading some issues here where some people were just replacing the "fuel regulator" at a fairly low costs. How hard is it to replace the fuel pump and what is a ball park cost for doing it?
#204 of 333 Hard Starting 5.3L by sierraz71 May 21, 2008 (10:13 pm)
Have a 2001 GMC Sierra 1500,5.3L with 144k miles. Recently developed hard starting problem. No trouble codes present.Cranks with no start until 3rd attempt. Probably would start with one attempt if I didn't let up on starter. Prefer 3 short attempts to avoid damaging starter. Occurs after shutdown of approx 5 minutes or overnight. Will start OK if you shut down and restart immediately. Fuel pump and filter was replaced at 120k miles. Runs fine otherwise from idle to WOT. Have noticed after shutdown,can hear noise in the fuel tank that sounds like fuel pump is still operating or more likely pressurized fuel is returning to the tank. Replaced original plugs and wires since they were long overdue. Truck has run flawless since purchased new. Any ideas where I can start to troubleshoot ?

#205 of 333 96 sierra high idle speed by scout8 May 22, 2008 (4:31 pm)
I have a 96 GMC sierra that speeds up it's idle not at first,but as soon as it warms up,to about 1400 rpm. I also seem to have an excessive amount of vacuum or just very strong vacuum. Other than that it runs well. This is a 305 with central sequential injection. Any feedback is highly appreciated! Thanks

Replying to: coyotehunter (May 23, 2008 6:29 pm) I had a similar set of symptoms on an old car once. I found that the air duct going into the intake was cracked between the air sensor and the manifold. Everything was fine untill I put it in gear, then it would bog out and die unless I VERY SLOWLY fed the gas and built up speed.   The replacement was pretty expensive from what I remember. If this is the problem, a half of a roll of duct tape will work just as good as a new air duct!   Good luck, let us know!
#208 of 333 1994 GMC Sierra all of a sudden bogging down by jpmoore Jun 01, 2008 (1:44 pm)
Yesterday out of the blue all of a sudden my truck started bogging down, and the fuel gage went from half a tank down to E so I turned around and pulled into the gas station put 20 bucks in and started out of town again....well it didn't stop it kept bogging down especially when I would go to take off....then it took forever to get home, cause I had to go really really slow to get up a hill and had to roll back down one cause it just wasn't going. I checked the fuel filter and it seems fine. Do you have any ideas??? There was no warning it just started bogging down when I accelerate. I'm going to check it out again here in a sec, any ideas would be greatly appreciated.....Thanks! it acts like its not getting enough gas or something.
