Can be any number of problems but the most common problem causing that type of stalling is failure of the THROTTLE POSITION SENSOR. Less common causes include ECM failure and various sensor failures. If the CHECK ENGINE light is illuminated or flashing when the car is idling, the error codes may help reveal the problem. If not, start by checking/replacing the TPS (Throttle Position Sensor).

SOURCE: Won't ''rev'' up when pressing on gas pedal.

The most common cause of this is a defective Mass Airflow Sensor, it is located in the air intake hose to the engine, here is a picture. this sensor will not in most cases turn on the check engine light.

SOURCE: Buick Regal dying

You have a problem in the fuel pump relay circuit for sure then. I'm betting the relay, but it could be that dropping resistor.

SOURCE: buick regal 92 3.8L Horrible fuel mileage

Sounds like you might have an oxygen sensor problem. Your catalytic converter(s) maybe defective or dirty. That in turn can dirty up the oxygen sensor. A defective oxygen sensor will send faulty info to the computer, interpreting the fumes as cold (even when the engine warms up). That causes the computer to adjust the fuel mixture to very rich, giving you poor gas mileage and the fuel smell. Hope it helps.

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.

i think you might be right it sounds like your engine is getting over fed fuel you are probably not getting very good fuel mileage either the 3.8 and 5.0 would defintely require the same volume of fuel it is probably playing havoc on the pressure regulators i would get another fuel pump and start there

My 1990 park avenue has hesitation and sometimes shuts off but will start back up goes a mile or so and shut off again


Look at your fuel filter or fuel pump or a bad fitting on your gas line. If the code p0756 shows up. It will be your SHIFT SOLENOID B CKT PREFORMANCE or STUCK (OFF). But more than likely look at your fuel pump.

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.

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.
