Question about 2000 Buick Park Avenue

1 Answer

I can not find the neutral safety switch on a 2000 buick park ave

Even the Buick Parts guy has not found it yet. It should be external, my book said 2001 and later are internal. My problem is I turn the key, dash lights and radio go out (normal), but starter wont run. No sercice light, no codes in ECM, tried 2 different batteries, all fuses OK, swapped relays in fuse box around, did this a week ago, turned key 3 times and then started. I can turn ignition on, lay under car, in park, and jump power from starter solenoid batt. post to small start post, engine starts and runs for 1 to 3 seconds, then like you shut key off, dies. Can do this several times, same result. Is gas in fuel rail on top 3.8L engine. Thanks Muck, Roger Jones I have the exact same problem. Installed new starter & selonoid & battery. Replaced relays checked all fuses, cleaned battery & starter wires. Same problem still exists

Any chance your vehicles have a security/alarm system. Disconnecting battery on some, will arm it sometimes & not allow it to run. Using key to unlock door, on driver & passenger side have been known to work on some vehicles, but if not, a call to dealer should help.

    I wouldn't think it should make any difference. If you lock all doors & the use key to unlock them, usually one of the front doors, so I'd try both, plus I'd try any key that came with the car that works on unlocking doors. I've heard of some that have what they call the valet key, that only will work. Can't be sure on yours but you may want to google "disarming security system" and add your car to it & see what ideas come up.

I have a 1992 buick roadmaster limited edition and my reverse lights stay on all the time how do i fix this problem

Hi...sounds like your Neutral Safety Switch needs to be adjusted. Loosen screws enough to slide switch one way or the other until your backup lights go out when the vehicle is in park, then re-tighten screws. Check to make sure backup lights come on only in Reverse. Here is a link showing the location of your Neutral Safety Switch: (copy and paste entire link into your browser if the link is not live)

I have a 1995 Buick Park Ave Ultra. The car has power but will not turn over. I was told by one shop that it might be the V.A.T.S. system and by another that it is the IGNITION CONTROL MODULE.

Make sure the battery cables are clean and tight on the battery. Check to see if the wires to the starter are tight. Try starting it in neutral to make sure the safety switch is being make. Also hold it up into park and try.
