Question about 1985 Buick Skyhawk
Fuel is coming to carb. Recently changed fuel filter. Checked fuel pump, works fine. Spark to plug and distributor is yellow not blue. Can that be the issue. New spark plugs, wire, distributor cap and rotor. Was running fine until recently when it began to run very sluggishly and cutting off randomly. Now just won't start!! HELP!!

The chance of the Power Train Control Module (PCM) failing is very small, about 3% per industry research, so expert ndguy2481 is giving bad advice, it is more likely the crankshaft position sensor or the ignition module have a problem when they warm up. Run a test on the PCM to retrieve the trouble codes, I know there will be some. The connector to do this test is under the dash below the steering wheel under the dash panel.

Did you mean coil the 1994 3.1 did not use a distributor , sounds like a bad coil pack and cylinders #3 and #6 do use the same coil. I would also check 3 and 6 plug wires this system is a waste spark design meaning when # 3 coil fires it is supposed to go through #3 plug wire , through #3 plug ( ground) through the engine block through the #6 plug then through the #6 wire then back to the coil, Then when #6 fires it works the opposite way, so in theory you could have one bad wire affecting 2 cylinders .....
