1999-2007 GMC Sierra: Not having enough power

Tue, 23 Jan 2018 22:32:41 -0700

I got a 2001 gmc sierra 2500 with a 6.0 vortec and I feel like it isn't getting enough power and its sucking up too much gas...I think so but I really don't know, I have seen the needle on the gas meter run to E as I hit the accelerator....not outrageously fast but I could tell the needle went down more than it was supposed too... It has a somewhat new trans. But when I hit the accelerator it docent take off like it should and it build up rpm before it jumps into second gear but after that it shifts pretty good and when I gas it to to about 70 mph the abs and brake light comes on...

1999-2007 GMC Sierra: GMC sierra 5.7 only starts when you arc # 3 plug wire

Sun, 29 Jan 2023 10:08:08 -0700

Ok never seen this before and have no idea 2000 GMC sierra 5.7 will not start. I was checking for spark on the #3 plug to see if I’m getting fire and the truck cranked and ran smooth as long as I’m jumping it to the exhaust manifold. I tried it on all other plug wires no start it only cranks when you arc the # 3 plug wire. Also hooked the wire back up while the truck was running and the truck died no start until I jump the wire???? Any ideas I need y’all’s brain power thank you

1999-2007 GMC Sierra: What is rear diff oil burning up so fast?

Sat, 16 Mar 2019 09:52:24 -0700

My rear diff oil is black and smells almost immediately after changing it to fresh recommended oil.

The previous owner I believe never changed it but I have had it changed twice in the past two days.

both times it was black with only a 30 minute ride.

Also after driving on a dip the howling sound started and has not stopped even after the diff oil changes and a center barring mount change.

pls help
