Engine light came on to service engine soon and a cloud of blue smoke came from behind the car. What could this be?
what is the cause of the water forcing the belt off and what is the fix?

When it;s raining and if I'm driving next to the curb, and hit a large puddle of water the POWER STEERING/ALT belt will be forced off the pulley.
The car clunks very rapidly when accelerating hard from a stop. When gently accelerating there is no problem. The Buick dealer says it’s over $3000 to repair . The car runs well other than there is a gas smelll that the dealer says is a gas regulator. $268 to repair. I’m trying to just get this car to keep running for local trips, only 27000 miles on it since it’s parked for 9 months of the year. It’s my winter Florida car
Hello, I have a 1997 Buick Park Avenue without super charger (non Ultra). Upon driving it stalled and I have since found the problem to be the fuel pump. Finding mixed messages online regarding the access panel being in the trunk, and some saying the gas tank needs to be removed. Seems the vehicle had the access panel installed in the trunk right around 1996, 1997 or 1998, this I am unsure and wish to know from anyone who has done this work on this vehicle before.
I also plan to install the optional Super Charger, for the engine was replaced recently with one that only has 2k miles on it essentially making it a brand new car, if anyone knows of a good model, place of business to purchase I would be very appreciative with both information.
Thank you very much in advance,

Note this is vehicle is a California model.
