I have a 96 Riviera, 3.8 Supercharged engine, and up until yesterday, the car has been running great. Yesterday I had an oil change and a tune-up that included replacing the fuel filter on the car. I just filled up with gasoline. Things were great, I drove the car to work, a distance of about 20 miles. After that, last night after work, it would not start at all, nor crank. A local "mechanic" seems to think it may be a fuel pump assembly; upon checking the price on this, I want to be SURE that this will fix the issue, since the fuel pump assembly for my car is NOT CHEAP. Would ANYONE have any suggestions as to what the issue with my car is, or is replacing the fuel pump the only possible fix? HELP PLEASE!!!
My friend has the same problem with the same exact kind of car when it doesnt crank over see if your security light stays on if so its your anti-theft system. check your owners manual under the security light portion.if the anti-theft system detects a problem with the chip in your key it will shut down the starter and the feul system for 3 minute intervals.

Re: 96 Buick Rivera, won't start, won't crank
Whoa!! hold off on the fuel pump. If the fuel pump is in need of replacement, the engine should still crank over. To make sure we're referring to the same scenario, when u turn the key, the engine does not crank (turn over)? Is there a clicking sound, or absolutely nothing happens? If the engine is not 'cranking over' !st thing to check is the battery to see if it needs a charge, or if u can jump start the car. Check this 1st (and let me know if I understand the problem so far), and we can take it from there to see what's wrong.

check battery connections at battery and starter ends. Check fuel filter, fuel pump relay, or maybe fuel pump is too weak to run engine at speed or under load. Can be coil or igniton module, map sensor, crank/camshaft sensors. Your description is pretty generic, so it possibly could be one of those "search till you find it" type repairs. Keep this in mind: In order for an engine to run it must have three things. Fuel, air, and spark. Air is easy to get. Fuel problems could only be the relay, pump, fuse, injectors. Spark is more hard to get, as you also need spark at the right time. So check igniton last, it gets real costly as you go. Coil, ignition module, any and all sensors ect.
Faster and safer to drop the whole unit from the bottom with the cradle. Replace the supercharger snout bearing and seal before you install the replacement engine and the supercharger belt. Also replace the boost valve to your transmission just to ensure your getting the proper transmission line pressure throughout your transmission.
Thank you for using fixya and be safe
1991 Buick Rivera only came with a 3.8L engine known as the 3800
The crank sensor is behind the Harmonic balancer / Crank pully. Special tool required to remove pully without damageing it. once pully is off the crank sensor is held inplace by 2 bolts.
no. But the only thing a under crank pulley performance is, is the gap and lightweight material used. You can go to custom shops and they can machine it for you under $200. dont know why you would want that. It really does not increase that much performance. But if you have the supercharged model than you can also try to look it up by other engines just like yours. Lot of cars have the same model engine. For instance
1986-1995 pontiac bonneville, oldsmobile delta royale, buick lesabre, oldsmobile toronado, buick regency. Lot of engines out there have the same specs, but might be available in performance parts under those names.
