I have 1988 Buick century v6 3.8 had sitting for Little while but I put starter, oil change , gas in it , alternator , then they had spark plugs wire on wrong so I put it on right , it crank up like a champ but I let run for lil while then I cut it off for little , then try crank it, now it acting like it want run , it act like it but still ain't running . What could be the problem ?

The firing order for a 4-cylinder 2.2L Buick Century is: 1-3-4-2. The distributor rotates in a clockwise direction, with #1 plug wire located at the upper left of the distributor The firing order on a 3.1 v6 is simple. 1-2-3-4-5-6 See a diagram of the 3.1 and 3.8 here. http://www.2carpros.com/forum/1999-buick-century-spark-plug-firing-order-vt177159.html http://autorepair.about.com/od/enginefiringorders1/
