    Thanks, Found problem. After replacing fuel pump which was needed, and control module found one bad fuel injector. For some reason this year of GM product has different wiring in the computer causing all six injectors to stop working. Repaired problem...car running great. Thanks for your help.

You might try a crank sensor, most of the time if you pull it out you may see a crack in it. It's between the top of the oil pan an the transmission, good luck.

1990 Buick Regal 3.1 has rough idle, hesitates and dies when accelerating.


A lot of new parts! Have a compression test done to gauge the engine's internal condition, and go from there. If compression is good on all 6 cylinders, scan for trouble codes. The compression test may find your problem, something like an exhaust valve burned or not seating properly.

2001 Buick Regal keeps stalling and running rough has white smoke coming out of tail pipe


The upper intake plenum is leaking coolant into the cylinder heads. The head gaskets on this motor are awesome. So, chances are it's the upper intake plenum. You can check this, by removing the vacuum hose that runs between the upper plenum and the brake booster. Stick your finger in and try to touch the top of the lower intake manifold. If your finger is wet it the upper plenum. You might as well replace the lower intake gasket while you're performing this work because they are prone to failure also. Use a shop vac to pull any coolant out of the cylinder heads. Get brand new spark plugs because the old ones are probably fouled. Once you get the plenum and gaskets replaced, remove your fuel pump relay and leave the spark plugs out and turn the engine over repeatedly for about 10 seconds to push any excess coolant out of the cylinder heads. Then, put the spark plugs in and turn the engine over for 10 seconds again. This will burn excess fuel as coolant out. Then, replace the fuel pump relay to allow fuel to be pumped into the heads. Car will smoke for a few when it fires up, but will clear out quickly. CHANGE THE OIL! Twice within a week if possible.

You have leaking engine cylinder head gaskets, this may be the cause of the overheating or a result of it, replace the head gaskets and have the radiator cleaned by a by a radiator repair shop, that should cure the problems.

Hello i have a 1995 buick park avenue that has a rough idle and stalls in the mornings after sitting over night the first two or three times it will stall but after that it idles rough til it gets warm,ok...


Try plug wires, that's about all you haven't replaced. Actually if you have an ohm meter you can test them - anything over 6k ohms per foot - REPLACE them. Also run a good fuel system cleaner through it and stay away from cheap gas.

I have an 1990 buick regal custom and stalls when im griving it then dies can anyone help me on how to fix it.


Sounds to me like a fuel filter.When was the last time it was changed?Because if a car starts and runs till you give it gas under load then dies it is a fuel problem.Start by chaging fuel filter and if problem still persists then next thing to check is fuel pump.
