Car Sometimes Won't Start

There is a bad connection or a cable going bad possibly, may want to try a new starter relay, cheap try. The other thing this sounds like would be the ignition switch. May want to have these things checked out.

The bad ignition is a known problem...

There is a problem with starting car Buick LeSabre 2003 I can't get a boost and it going to run but once I kill it and try to start it again it's just making a clicking noise

I changed the ignition switch on my 2003 Buick lesabre and it was cool for a day or two then started back with this problem , the battery icon appears but I don’t think it’s the battery , changed the starter and alternator already

No answer on how to fix the problem. Only to say my LeSabre does the same thing.

Having the same problem. It appears to be the ignition switch, because the dash lights go dim after 2 to 3 seconds then goes completely out. When I wiggle the key, the dash lights back up. Security light appears to be acting normal, not flashing erratically.

Buick Lesabre 2000 won’t start won’t crank , it started after using jusmper cables (didn’t see a spark though). This morning I went out to start my car and same thing happened , what else could be the issue? It has been pretty cold outside around 20-30 degrees

Buick is garbage.

i have a 2003 buick lesabre custom and im going through that now i can jump start it from the front fusebox where it connects from the battery ive replaced all fuses from that fuse box and other fuse box under seat like who was smart about putting the batt in the back under seat makes it hard to jump but yea same thing here pretty much all new fuses and the other fuses max fuses still dead but a jump not a prob there any ideas cause im lost on this one
