check the engine family (4gh6 or what ever) later engines in the same family will fit and will probably have increased power. Problems may arise from the sensor s and the ECM as there may be differences. A good place to check out is google-type in your engine make and size and read wikipedia as they list vehicles with engine families and power ratings.

I would start by replacing the battery in the key fob remote that goes on your keychain. You can take it to most auto part stores and they will test/replace the battery in the device. It's a fairly cheap fix. If the device still isn't working after a new battery, then you will need to replace the fob. Some auto part stores like, AutoZone, will carry some of them but some you need to go to your local GMC dealer.
