Question about 2002 GMC Envoy

1 Answer

Starting problems... my 02 gmc envoy is starting difficultly... it chugs for a few seconds and eventually starts and when it does start everything is reset (radio/clock). if i start it and shut it off and then restart it it takes even longer to start up. Is this just a battery issue or something more?

Car no start problem is sometimes very difficult to confirm. You try all the possible things, but still you get no fault and problem is still the same.--------
In that case, you need to check few things individually.
Check the spark,the battery,the crank, the fuel and other most possible parts. Click this link below for more details:-- http://howtobyme.blogspot.com/2011/10/car-troubleshooting-tips.html

2003 Envoy intermittent display, radio, ac control, shift, comp.


This sounds like your alternator maybe going bad. When your alternator starts to go bad lights such as headlights, radio lights will go dim wipers will start to move slower but if you cut one of the things off such as the wipers the lights will get brighter for a few minutes then not long the car will shut completely down. Hope this helps.

My 02 envoy will not turn over


Sounds like the ignition switch. Does the tack when you first turn over the switch jump down and kinda start to climb and do the indicator lights under the tack cluster pulse dimb and bright? They should be bright .

Endine stalls on occasion after a cold start. No codes on dash, 170,000 on engine no oil burning new wires , cap and rotor air filter clean. Any tips ?


related to a dirty throttle body. In order to clean it properly you must disconnect the battery and remove it. Not very difficult to do but it will make a big difference in the idle smoothness and fix the stalling. The PCM will reset after you disconnect the battery for 15-20 min and take a few drive cycles to re-learn everything
