Faulty cam sensor maybe - it controls the injectors. To diagnose, when you get a non-start, spray a V.small squirt of easy-start(ether) and if it runs a little then you have a fuel issue. The spark timing is controlled by the crankshaft sensor so that can be faulty and cause a mistimed spark but usually you'll get a mis-fire in those cases.

Hi,
Chances are this just a random engine misfire caused by bad spark plugs or bad ignition wires. Basically get a tune up and replace the ignition wires (spark plug wires) and your problem should be solved. Have a good day.

Where are the spark plugs located on a 1992 buick century? and how do i remove them? and could you send me a picture or video?


Your Buick either has the 3.1 V-6 or probably the 3800 V-6...you can trace each spark plug wire to each spark plug...I recommend the AC plugs platinum tip as your Buick came with. The Auto Parts store can confirm the spark plug gap...change only one at a time...so you don't confuse the firing order...sorry no pics available... Also use anti seeze on the plug threads...and use lubricant to seal each plug wire at each connection...also makes them remove easier next time...:)

Car died. changed fuel pump and both filters. car will turn over but will not start. any help is appreciated.


Check for spark and fuel as a starting point. If you're getting fuel pressure at the rail, then the fuel pump and filters are not the problem.

Possible crankshaft sensor if the spark is not getting to the spark plugs in the 1992 Buick Century.
