LeSabre custom 3.8L

  • Automatic transmission
  • 199,887 miles

So the door locks issue is just the first of many problems with not only this car, but another Buick Park Avenue, and to be honest I would never f** touch another Buick as long as I live.

So to start off a year ago I bought a 90 7 Buick Park Avenue with 170,000 miles on it. We took a first test drive and it rode like a dream. Dyna ride quiet luxurious nice smooth ride car - it ran great with 3.8 l in it. After about maybe the second day we began to notice some intermittent spiders in the car some different blinking of lights in the radio, and on the dash in the in the climate control system, it started blinking. The radio started doing some weird things, and then just driving down the street it would die and would not start back up for 10 seconds if you shut it off (the key all the way off). After about 10 seconds with the key off, it would start right back up and drive around on the road depending on how hot it was outside.

It ran great for a few weeks until just yesterday when my wife called me from work and said the car won't start. Let me go back a day before, that she came home for lunch and when she went to go back to work, the car wouldn't start. Some YouTuber had posted that if you pull the fuse for a couple minutes and replace it and reset itself. So I'm thinking, well, maybe I burnt out the relay or there's another problem that gets fuel pumps a little crazy - maybe it's the fuel pump.

I checked put a new relay in - still no start. I get it towed home, take the battery out and try to reset all the control modules by connecting them together for a short amount. When I reconnect the battery and turn the key on to car stereo starts just going nuts so I turn the key off. The dome lights wouldn't work and then the headlights wouldn't shut off, the windows won't roll down, the fuel pump won't come on. If you spray starting fluid in the ignition or in the intake it will fire, so to my conclusion it was the body control module - but that's good power to the relay.
