The pump is in the fuel tank. you either have to drop the tank or there is a access hole in the trunk. did you check fuses and relats?

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 have a 92 buick regal custom it wont start i think its fuel related i replaced the filter and bought the fuel sendind unit it goes under the hood like a big fuse but i dont know wich slot to put it in...

Hello sanman1206: My name is Roger and I will help you. First you need to test the fuel pump. You can do this by locating the fuel test port. On o 3.1 engine you will find it center of fuel rail on passenger side of the rail. On a 3.8 engine you will find it on the passenger side of the car right fuel rail. The fuel pressure for both engines are key on engine off 40.5 to 47 psi.Any less and the car will not start. The fuel pump and sending unit are both located in the fuel tank. To gain access to the fuel pump you will need to drop the fuel tank. This is a messy job and best done from a hoist or at least with plenty of ground clearance. Should you need further help please just ask. Please rate the response to your question. This way i know it was of help. Thank You for using Fix Ya. Roger.

Lost owner manual for 92 Buick Regal custom-power steering fluid

The reservoir should be located under the hood on the passenger side, above serpentine belt. Guide your eyes backwards towards the mid section of the engine on the passenger side. the small reservoir will have a small turn cap on top. (passenger side off vehicle)

I have a 1998 buick regal it will start but won't stay running for longer than 2secs


If your 1998 Buick Regal is the GS model (supercharged), there is a resistor that is either switched into the circuit to the fuel pump or it is bypassed. The idea is to not put as much voltage to the fuel pump under idle or low load conditions. However, under high power conditions, such as when you punch it or drive up a steep hill - which usually also brings in the supercharging, then the circuit bypasses the resistor to give the fuel pump more voltage and, hence, more fuel pumping capacity to meet the higher fuel demand.

The resistor is located in a bad spot where it can pick up lots of road debris, slush, dirt, etc. Thus, it can fail. When that happens, you can start the car but then the resistor circuit is activated and, because the resistor has failed, no voltage gets to the fuel pump and it shuts off, then the car shuts off. If you immediately hold the accelerator down after starting the car (but not to overspeed the engine), the engine will keep running but at a very high RPM.

The fix is to replace the resistor, or bypass it altogether. The resistor is located on the inner front tire wheel fender on the passenger side. If I remember correctly, you get to it under the car, but you may also have to access it by opening the hood and reaching down from the top. It was 10 years ago when I fixed mine and I do not remember. This fixed the problem for me. I hope it works well for you. If you have other questions, you can reach me at
