2006 GMC Envoy Xl - Answered Questions & Fixed issues
I have a 06 gmc envoy xl 4.2...battery meter fluctuates back and forth from 14 Down to 9.
Bad plug or broken wire at the plug, at the alternator. Pull the plug off the alternator. Turn the key on and check for power and ground at the leads. No reading, probe the wires a couple inches back. If a read there fix or replace the plug. If you have a 3 wire plug, best to use an ohm meter. Test each wire separately. At the pin and a couple inches back on the wire. This test may include testing the wire back to the PCM and fuse panel. You'll need wiring schematics for this. The PCM is what fields the alternator to charge and supply power when the engine is running.

This is a known problem, a software update to the PCM takes care of this problem. An update at the dealer is around $100.

Replace timing chain
Timing chains last the life of car or truck belts need to be changed every 100,000 km or more. Also what's the problem.
Oil pump replacement
This is a major job. you have to remove the engine mount bolts, raise the engine to the point that it's raising the vehicle, remove the oilpan on the bottom of the engine, remove the oilspash pan, then remove the oil pump. Are you sure this is what is wrong? Oil pumps last for almost ever. If you ran it out of oil, it is most likely main and rod bearings. If you didn't run it out then it could be an oilsending unit gone bad. If you give me more details I can narrow it down. your year should not need an oil pump.
