The PCM has a "learning" ability which allows it to make minor corrections for fuel system variations. If battery power is interrupted, a vehicle performance change may be noticed. PCM module corrects itself, and normal performance returns if vehicle is allowed to "relearn" optimum control conditions. "Relearning" occurs when vehicle is driven at normal operating temperature under part throttle, moderate acceleration and idle conditions. Good Luck :-)

It's my understanding that on these cars if you disconnect the battery for an amount of time the car computer shuts down and all the memory is lost till you reinstall the battery again. Then it takes a while for the memory to come back. The engine will stall and not run properly till the computer completely resets itself. They say just drive it and eventually in a few miles it will just keep getting better .
Hope it works for you.

SOURCE: Buick Rendezvous 2002 need codes?

the BCM needs to be programmed to operate the computer. a GM techII is now required to calibrate BCM to airbag, stereo, keyless entry, and control pcm data. This is required to make it all work. a gm service should have it done within an hour or less just call and ask them how much it would be to program new BCM. it might cost @$75 to $125 but it is needed, to allow the BCM to work properly.

Testimonial: "ok...i bought the bcm on line (used)...but the gays in the dealer says i have to buy a new one..because the used cannot be to reflashed...or recoded."

SOURCE: 2002 buick rendezvous

My gas guage went from Empty to Full on its own and I never knew how much gas was in my vehicle. I was driving the other day and it stalled. Pulled into a parking lot let it sit a bit and it started right back up and I was able to drive again. Went to nearest gas station to put gas in. I put in $10 and I drove 3.4 miles and well it died on me again. I pushed the vehicle into my garage. I called around to see what could be wrong and I was told numerous things. I finally went under the vehicle where there is this clearish/white box under the Driverside area and I noticed it was corroded and dirty. I went in the house got a spray bottle with HOT WATER and sprayed it. I noticed that I had 3 prongs broke off. So I went to a local dealership for GM/Buick and I got the pins I needed to fix the problem and I went home fixed the broken pins and well now my vehicle works great and the vehicle runs great and gas guage problem was fixed as well. So for all of you that think you might have a fuel problem, fuel pump problem or gas guage problem check into the wire harness box under your vehicle and you will be able to fix it for Pennies instead of paying the $750 or more for something you cna fix at home. I love my Rendezvous and I would buy another one again.

SOURCE: I have a 2002 Buick Rendezvous CX with a locked radio.

what you need to do is pull the radio out and write down the serial number then call the dealer for the code. they may charge you 15-25 bucks but that will save you some money

Where is the alternator fuse located in a 2002 Buick rendezvous?


There is no fuse as such. There is a fusible link on the generator bat circuit. You can use a test light at the bat terminal on the generator, key off, hot all the time, it's battery voltage. If nothing there, could be something wrong with fusible link or the wiring circuit from generator to battery.
Have to make sure battery has a full charge and battery connections clean and tight. You can't do any testing if battery is down.

Did you check for fuel pressure with a fuel pressure gauge before replacing fuel pump ? Did you test for spark ? Is there compression . Is the security light lit on the instrument cluster ? anti-theft system stops injectors from working if a problem is present. You changed the battery ? Battery Disconnect or Replacement Problems

2002 Buick Rendezvous has Power to lights, horn etc, but won't start. Just get a clicking sound. Battery only 6 months old.


Have a load test done on the battery as it indicates a dead cell . Check that the battery posts and terminals are shiny clean and tight. There is no real life span on batteries and that is what warranties are for.
