Engine shuts off while driving

test the fuel pressure sounds like fuel pump getting hot and shutting down

I had a similar problem....my 98 regal GS did the same. There is a two stage fuel pump resistor located in the right inner finder. It was corroded and open. The fix requires relocating new resister on firewall. Fix was $165.00 + tax to my mechanic and runs like new now. Hard to diagnose problem per mechanic.

It is most likely a crank sensor!!!!!!! i am 99.9999% positive that this is the culprit. I am a mechanic and this is the first thing i would check with your description.

it is electrical on your car there is a computer that will kill the motoe if somthing isnt safe, it sounds like a code reader mabe your best option. you can rent these from your local auto parts store.

CHECK FUEL PRESSURE IT SHOULD BE 41 - 47 PSI. IF NOT REPLACE FUEL FILTER.IF NO CHANGE. REPLACE FUEL PUMP.IF FUEL PUMP IS GOOD.YOUR PROBLEM COULD BE A INTAKE LEAK OR SPARK IGNITION PROBLEMS.ALSO USE A SCANNER TO CHECK FOR FAULTY SENSORS OR THEFT DETERENT PROBLEMS.

ok its one of two things you need to check when it cuts off if you have spark or fuel if you lose fuel pressure replace pump it gets hot and makes noise like its running but its not pumping fuel and if you lose spark you need to replace ignition control module has a hair line crack in it and when gets hot the crack expands and loses contact and wala no spark

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.

On the regals they have a ceramic resistor on the passanger side under the fender. It heats up and over time it tends to brake and the wire inside tends to rust away. The fuel pumps run in 2 different speeds. Had the same problem. Dealer only part yet the car would run and you would think it was the fuel pump. Turn the key it kicks on then start and dies out. Ceramic on the pass side would need replaced. It is white about 2-3 inches long or so held on with 2 bolts i do believe. Ill find a bulliten i found online to help me diagnos the problem. :) hopefully this helps someone out instead of spendin $$$ that ya cant afford with the recession eh?

In my regal gs 1998, the fuel pump is n fuel tank. There is a resister that I replaced to fix stalling and shutting down of engine.

Greetings,

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 [email protected].
