#443 of 511 Re: 1999 GMC Suburban Vibration [gangluff] by bstaples1 Sep 22, 2008 (8:57 am)
Replying to: gangluff (Aug 10, 2007 3:37 pm) I also have a 99 same thing was happening to me I learned that on my truck I have full time hubs or vacumn hubs witch means that the tires are locked to the drive shaft not both at same time but all i could figure is that at high speed the front drive shaft would vibrate and as i would come to a slow speed it would bind as to apear tight when lightly checked how I found out was I droped my transfer case do fix a leek and the drive shaft about fell apart it was so worn out. hope that helps.

#445 of 511 Suburban will NOT START by simmy Oct 06, 2008 (5:23 pm)
I have a 95 chevy suburban 2500 that absolutely will not start. The fuel pump was replaced and I was able to make 4 stops. Well on my 4th stop it wouldn't start back up. The fuel pressure was checked and that was fine. Changed the fuel relay, coil, battery, throttle body, injectors, checked the spark plugs, changed the distributer and the o rings. Still nothing. The mechanic is not figuring out what is wrong. The fuel is coming out when we place a wire from the injectors to the battery, but when we take the wire off then NO FUEL. Everything has just about been replaced. Can someone PLEASE give me an idea of what the heck is going on I would greatly appreciate it. I am so frustrated Replies to this message: Mr_Shiftright (Oct 06, 2008 5:29 pm) spence57 (Oct 06, 2008 10:48 pm)

Replying to: simmy (Oct 06, 2008 5:23 pm) Okay let's back up. Were the injectors checked for pulse with a NOID light during crank?   Not sure exactly which component sends the impulse that tells your injectors to open, but that's where I'd look if the noid light says no impulse.

Replying to: Mr_Shiftright (Oct 06, 2008 5:29 pm) Your mechanic needs to stop guessing. He should check to see that fuel is getting to the cylinders at the appropriate time, as is a strong spark. There also has to be sufficient pressure in the cylinders at the right time. If a pressure gauge indicates the proper compression pressures then you can assume that the cylinders and valves are in sync. You can then check the number one cylinder TDC point to make sure the timing mark corresponds with it. Then a timing light will tell you when the spark is timed for. Finally using ether will tell you whether the cylinders just aren't getting fuei.
#448 of 511 Ignition Switch by bobby61 Nov 12, 2008 (1:17 pm)
My wife has a 1994 Suburban, today she called me from work saying she could not turn the truck off. She said it would not turn to the back position, but it would turn to the foward or start position. I need to know how hard it is to replace the key switch. It does have tilt steering also. Thanks Bobby
