1 thing to check before you go replacing the PCM. We have plastic intake manifolds which are right below the PCM where your heat lamp was. With temperature related problems similar to this, I'd check the manifold bolts for tightness (these have a tendency to become loose causing vacuum problems). Easiest to check are #5 & #6 near the firewall. When the engine warms up, the plastic will expand causing no problems, but when it's cold, will contract and have vacuum leaks. Do you have any check engine lights? pcmforless.com is a good sight for repairing PCM problems if you deem this is indeed the problem. You can send your PCM in and they even send you a loaner PCM while yours is being repaired, but they have several programs to choose from.

Crank sensor 06 envoy


Crank Sensor is at bottom of engine, driver's side, back towards the back of engine. Do like I did. I looked at new part and found it by looking on you tube, then getting under vehicle and seeing where it was.

While drviing down freeway today the 2.5 ltr engine died and will crank but will not start. one month ago it was backfireing in intake and dieing on freeway and i thought i had bad gasoline it fixit


you need three main conponents for the engine to run,fuel,spark,compression . first have someone to crank the motor and put the spark plug lead of the plug and hold it near the block and if there is spark it will jump a inch or so, check the fuel filter , hold the fuel line clear of electirical and heat, crank engine , fuel will flow, when engine is running but running rough as a miss fire disconnect plug lead one at a time till you find missing cylinder

Runs rough after cutting on heat some times engine will die but when you cut the heat off it idle ok


Are you sure you don't mean defroster? With defroster on the A/C compressor runs and it will drag a engine down if defective. Disconnect the wire to the A/C compressor and see if it does it then.

I have a 2006 envoy and the computer is on the motor it will crank and die but if i put a heat lamp on it or by the computer then it runs do i need a new computer


Sounds like you are getting moisture into the computer, or there is some other type of electrical glitch going on. From working on cars my whole life and seeing this issue in the past, I would say to take it to a Chevy Dealership, they are going to have to run tests on the computer, but it does sound like the computer is bad and will need replacing.

Our 2006 chevy aveo turns over then dies when put in gear. Also, the cigarrette lighter and overhead light have quit working.


Idle speed is probably set too low. The computer should adjust this speed, so have engine codes run to ferret out any problems with sensors, etc. But first do this test: Crank car, let it idle. Raise hood, and move the big tube that goes to the throttle body a little. If the engine dies, you might have a tube that has developed a leak. Check all hoses for vaccuum leaks.
As for the lighter and overhead light, these are often wired to the same fuse. Check your fuses, Then check the wiring. Good luck with that!! Wiring problems can be a real dog to solve. With any luck, it's just a fuse.
