Try to prime the engine with fuel thru the throtle body before u crank the engine over if it starts u have a fuel delivery problem. may be possible clogged injectors or fuel filter. or a weak fuel pump.

If you have the same problem after the tuneup as before you may have an injector problem or possibly a mechanical one. Ie. valves, timing chain, valve train.

Have you checked out your air filter? Has your 02 GMC Envoy had a tuneup? Also you may need to replace your fuel filter as well. (especially if you drive in a dusty area) A vehicle as new as yours still needs preventive maintainence to keep the "new" parts working properly. While this won't stop the components from eventually breaking down and causing you headaches, its still a good idea to check these things.

Hello. I can assist you. You need to get your truck on a scanner. You can have this done at a dealership or at many autoparts stores, often auto zone [for instance]. the scan will isolate the problem so that it can be solved.
