#1296 of 1492 Re: Sierra Overheating Problems [adammc] by bigfur Dec 28, 2005 (6:36 pm)
Replying to: adammc (Dec 27, 2005 3:46 pm) When you checked the oil was there any coolant in the oil? I could be way off since im no mechanic, but sounds a lil like a head gasket possibly.
#1297 of 1492 GMC Sierra Cruise Control not working by ad5vp Jan 02, 2006 (8:00 am)
I have a 2000 GMC Sierra on which the cruise stopped working. When I turn it on (truck is stopped), I hear a click like it is on. When I get to speed (60 mph), hit the button in the turn signal, nothing happens. I have tested continuity from the steering column to the connector at the cruise module and all switches/buttons work. Before I go out and spend $400 on a new module, is there some thing else that I can try or do to check? Is there a separate servo to change? In the repair manual, it looks like the servo and module are all in one. Thanks Bren
#1299 of 1492 hard to start when cold by donwp Jan 03, 2006 (9:30 am)

#1300 of 1492 1998 gmc sierra will not start by woody12 Jan 02, 2006 (8:41 am)
this is a gmc 4x4 2500 with a 5.7 liter   I have had this truck for about 4 yrs and it has had this problem about 9 times (turns over great but will not fire) usually after about 3hrs to 3 days it will start and run great. I can't find out what is causing this problem. I have been lucky in that it never quits while running just after sitting a while. I have done these tests replaced the icm module,put a pressure gage on the fuel line and I get 60 psi with key on,I have spark at all the plugs, Have sprayed starting fluid in the throttle body while trying to start it. Thanks for any input Dan
#1301 of 1492 GMC 1500 4.8 cold starting problem by rcampbell Jan 04, 2006 (10:58 am)
My 2000 GMC 4.8 had the same cold starting problem (#1299, donwp) a month ago when the morning temps were around 0 degrees. I changed back the plugs to platinum (0.058 gap) from AC Delco Iridium (0.040 gap), changed the PCV valve, and cleaned the carbon build-up from the throttle bore. It didn't completely solve the very cold starting problem, but it'll start normally about 15 degrees colder now and the service engine light turned off the next day. We haven't had any single didget temps since then, but it's been running fine. Let me know what you find. rcampbell
#1302 of 1492 Re: 04 Sierra-won't turn over but lights, radio all work [bobyoung] by maffu123 Jan 06, 2006 (12:53 pm)
Replying to: bobyoung (Dec 15, 2005 5:19 pm) I have an 01 that does the same thing. Was told it was a chip in my key,that year doesn't have a chip. It is intermittent after it happens will run fine for 2-3months but started doing it more after hitting 100k miles. Have read on other forums that changing the ignition doesn't help. I get 12 volts to the ignition switch with key off.And 12 volts coming out with key on.STARTER RELAY has been replaced twice just to be safe.Checked small fuses. Today I went to start the truck and no dice. All dash lights came on.Wll not turn over or fire.   ANY info is helpful.... Truck is in driveway stranded as I type.
#1303 of 1492 Re: recall [gmcjoe] by wingsh00ter Jan 08, 2006 (8:20 am)
Replying to: gmcjoe (Feb 11, 2005 4:01 pm) Did replacing the Hub assembly fix the issue? I have the abs problem and brought the truck in for the recall work. The dealer said the sensors are working properly and the cause of the abs activation is due to the hub assembly. Hub assembly is not covered under recall and wants $500 to replace assembly. Burns me that they did not include the hub assembly under the recall. I filed a complaint for what it is worth. Will GM refund your money for the hub assembly? Not sure if it is worth fixing the problem as it sounds like it will most likely resurface again as it gets dirty.   Neighbor had work done even though she did not have the abs activation. Two months later, she now has the issue. Broke something that worked. The dealer had her bring it back in and replaced a sensor. Problem gone.

#1304 of 1492 2004 Sierra problems by travis77 Jan 08, 2006 (8:51 am)
I currently have a 04 sierra 4x4. It's the worst vehicle i have owned thus far. It only has 24k miles on it and has been in for numerous warranty issues. So here is a list from the start with what has happened with it.   clunks in transmission ,, yoke replaced,, didn't fix   clunks in drivetrain,,,, they said it was normal (pish posh)   power steering   radio antenna won't stay on tight   radio loses volume, i can turn it down and then try to turn it back up and get no sound   driver and passenger window motors went out   squeaky doors- every bump they squeaked   passenger door speaker quit   speedometer goes crazy- go about 65 on highway and speedometer pegs out 120 then stays stuck on 30 when i stop   when i come to a stop sometimes it won't shift down into first gear and trys to take off in second gear   I am now in the process of trying to have general motors buy the truck back,, i'm not paying another penny on it,, not worth the money they ask for. So if they don't buy it back then i guess i'm just gonna take it back to them and do a voluntary repo,, i already bought a new car so the repo won't affect me as far as that goes. I can't sell the truck do to the pay off being more than the truck is worth. GM doing there rebates don't help either as far as value goes.

#1305 of 1492 Re: recall [wingsh00ter] by gmcjoe Jan 08, 2006 (4:25 pm)
Replying to: wingsh00ter (Jan 08, 2006 8:20 am) Yes, I replaced the left front hub assembly (which included a new sensor) and the symptom disappeared and has not returned. I diagnosed the left side to be at fault in two ways - by the way the vehicle pulled when the anti-lock activated and by monitoring the sensor output voltage while rotating the tire/wheel with the truck in the air. The left side had the lower voltage reading.   Since the repair, I received my recall notice but have yet to bring the truck in. I really doubt that GM will reimburse me for anything but the amount it would cost to complete the procedures in the recall notice.   I also think it stinks that they are not willing to include the sensor and hub assembly in the recall. After all, they function as a unit to send the necessary voltage pulses to the ABS computer. They took the cheap way out on this one. Replies to this message: wingsh00ter (Jan 27, 2006 12:35 pm)
