one, five, three, six, two, four

The plastic intake should have this sequence molded into it somewhere, and even the corresponding cylinder numbers in front of their respective holes. Have fun, and thanks for posting on Fixya.com

SOURCE: 2002 gmc envoy shuts off when i turn on the ac whil ideling

If it does it when idling I would suspect an IAC motor (Idle Air Control). If it is opening too slowly the added air the motor needs will not be supplied fast enough and the engine will kill.

It could be other things also but this is where I would start.

Could be throttle position sensor. But, my husbands S10 Blazer did the same thing just before the tranny lunched. He barely got it home.

What does Fuel Level Sensor A Circut High Input for a 2004 GMC Envoy


The fuel level sensor is in the gas tank, and if it needs to be replaced, the tank must be removed from the truck.
Does your gas gauge work correctly? If not, there could be a bad connection at the tank/sensor or the sensor itself is defective.

It wont turn on,i have to give it some gas to make it come on.and when i press the brakes to stop it turns off and it pop up the codes P0440-P0014-P1345(gmc envoy 2002 )


P0440: This indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine, you will likely not notice driveability problems with this code.

P0014: This indicates a camshaft position sensor problem which could cause your driveabilty issues.

P1345: This is a crankshaft or camshaft position sensor malfunction which could also be an issue with your driveabilty, i would have this checked by a professional scan tool such as a modis.

You need to find a shop with a Tech 2 scanner. The pcm has to be recalibrated because when the fan clutch goes bad it back feeds into the computer and stores a hard code. And because the 02 is the first year for this style envoy its a pos! And these A**Holes from GM thought it was a good idea to have a electronic throttle body and gas peddle.

So in a nutshell it needs to have a PCM.AZ UPDATE AND YOUR DONE! SELL IT AND BUY SOMETHING YOU CAN FIX IN YOUR BACKYARD ON THE WEEKEND!
