Check the fuel filter. Also pull the IAC valve and make sure its not clogged up with carbon.

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.

Starts great idels great give it gas and it dies


This is probably an engine using a carburetor. If it starts and idles good and dies when the accelerator is pressed it is probably the accelerator pump on the carburetor. The accelerator pump supplies the fuel to operate the engine in this transition period from idle to part throttle until the venturi effect catches up to draw the necessary fuel the engine needs to continue running at the current demanded rate of speed. If the butterflies are opened and there is not sufficient fuel squirted into the engine when larger amounts of air are in demand it starves for fuel and thus stalls.If it is fuel injected then you have other problems, but my guess is it is a carburetor version. Ford went to fuel injection in 1990. You can just purchase the power valve if needed. You don't need the complete kit. Good luck

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.

95 Regal 3.8 Runs great but today started


Try a new distributor cap and rotor button,they are known problem areas.If the problem is not in the distributor then you will likely need to replace the catalytic converter,a plugged converter will not let the engine get to full horse power because it can't get rid of the fuel as fast as it is coming into the engine,which is not a problem for the engine at lower rpms but it is a problem when you need the power.

I have a 1990 Buick Regal that stalls while accelerating. And then wouldn't start at all. After letting it cool for a few minutes it started but continued stalling. Before this started happening it was...


most likley a fuel pump issue. The only way to know for sure is hook up a pressure gauge and when you have symptoms check the pressure. If you spray some brake cleaner or quick start when it doesnt start and it does start then this is an indication of a failed fuel pump or fuel pump relay. If it still does not start when you spray then you have an ignition issue like a crank sensor or ignition module.

1992 Buick Regal Custom keeps dying in gear unless I double pedal


unfortunatly it sounds like you are having issues with the torque converter. it sounds like it is locking up all the time now. this requires the transmission to be taken out to change it i do not know what your experience is so not sure if you have the tools or knowledge to do it yourself.
