My vehicle has fuel, will crank but not start. I hear the fuel pump kick in when I turn the key. Had the battery checked and ruled out. Is it the fuel filter or fuel pump?

When you start the vehicle there is a loud knocking that goes on for about 1 minute. There is no air coming from the front vents. What is the thing that shifts the vented air around? I wonder if it has somehow become jammed? Air works from floor and windshield vents.

It is running rough, set off warning light code replace MAP Sensor. It says I should try cleaning and replace before replacing the new sensor. I know nothing but neccesity drives the need to learn Help?


I was experiencing the sputtering until I changed the spark plugs and fuel filter, now I am having an issue with stalling especially when the heater is turned on and when in park. What is causing this?

I put gas in the car and it does not register correctly. could this be a sensor problem?


rear air spring is missing bottom support and is not connected to rear axel, when i jacked up rear the right side was just hanging there.

no codes are coming up

the lock tryes to lock makes noise but it don't move,and my wipers don't do any thing. i have change black control box on it and that is not it. could it be the wiper switch?

I can't eject whatever is inside. whats wrong? Can't feed rject

I can loosen them and slide them but I'd like to remove them. I read somewhere that it would improve fuel economy.

When the light first came on the cap was loose, but the light does not go away after tigjtening the fuel cap

The rear gate wiper motor failed and I had it rebuilt. I put the motor back in and when I try to put the window up the computer says "rear wiper obstruction". When I turn on the wiper it says "close rear glass".

When i park my vehicle overnight the rear sags. When i start in am the rear will come back up to height. This does not happen all the time.

I fill up with gas but the fuel light stays in empty mode.It sometimes moves backwards then forward indicating a full tank one minute then empty the next, does this mean that fuel pump need replacing?

Another dught I have is if it is going to start without the flashing, or should I replace it outside the dealer incase it does not start?

I recently purchased a 2005 GMC Envoy SLE, and the lights malfunction, the passenger window will not roll down (already replaced the motor), the doors will not unlock half of the time or when driving they switch from lock/unlock. I was told the truck had been submerged in water and the complete electrical system needs to be replaced.

We have already had the fuel level sensor failure problem fixed and have replaced the gas cap when the check engine light would come on intermittantly. Took the car to the shop for maintencence and they could find nothing wrong that would cause the check engine light to be on, so they reset the light. Subsequently, the light came back on (incidentally right after we hit a pothole) and has been on ever since. Any one else have this experience?

This is the 3 time this has happend

power driver seat will do everything but in cline back. help please

It could be a catalytic converter. However, it could be an O2 sensor or other item. The Envoy seems to idle poorly in park, with the RPMs moving from 300-800. It is like it can't determine where to idle. It seems worse with the air conditioning running in hot weather. I had a cylinder 4 misfire that I fixed by replacing the boot/coil, but didn't get the P0420 until after that was fixed.

I does come back on every once in a while and the air blows cold air. It may work for a couple of days and then go out again. (0nly in the front seat)

It worked but every setting resulting in the air or heat coming out of the defrost vents.

Driving down the road with low beams on, they sometimes go off randomly... I can then either turn on my fog lights so that I have some light or go back to high beams, but still no low beams, then on thier own, they might come back on at some point....

If I could be more specific I could probably fix it my self.

I need to change the unit

how much should it cost to replace oil pan gasket

If you do not have the transfer control module will it cause problems

I have been told the fan clutch on my envoy is bad. I have been quoted repair cost from $300 to $850. The engine has a growl on acceleration. I was told the transmission is OK.
