Engine shuts off while driving

1998 buick regal gs. While driving the engine just shuts off. We have replaced the fuel filter, fuel pump resistor, plugs and wires. The check engine light is not on. when the problem first happened the car started right back up and all the dash lights came on. since then no lights come on and it has taken longer to start back up. Seems until the engine cools off it won't start.

    The problem I have is similar to this, except it started out with not starting unless I held the gas. I would then have to keep my foot on the gas as I drive, sometimes. Most of the time after I was able to drive off and even the next time I started the car I wouldn't need to hold down the gas. I would appreciate any more help with this, Thanks!

I have a 99 Buick Regal GS, engine will start and run for few seconds then it will die.

I had a similar 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.

My 1998 Buick Regal GS will not start. The battery is only one year old and the starter is turning. The wiring for the spark plugs was replaced 2 years ago. Is this a fuel pump problem? If so I would like...

If the motor is turning over, then the battery is good. You are either not getting spark or fuel.
If not spark, the crankshaft position sensor is usually faulty.
If no fuel, either fuel pump or fuel pump relay is bad, or clogged fuel filter, or fuel pressure regulator is faulty. You have a fuel rail that has your injectors attached to it. It should have a test port on it that looks like a tire valve. You can put a rag on top of it,, press it in and there should be lots of fuel pressure, If not, either filter is clogged or pump is not running either due to bad fuse or relay or pump is bad.
For spark, there is a crankshaft position sensor that screws in engine block next to the crank. Then from here the wires go to ignition module and coil packs, then to plugs and wires. You can test any relay or sensor with an ohmmeter in the ohm position. You can test any power in an electrical unit with a voltmeter

ENGINE IDLES ROUGH, BUT RUNS FINE WHILE DRIVING. My car is a 1995 Buick Regal Gran Sport with the 3800 series motor with 212000 miles. The rough idle tarted after driving through some muddy and wet roads

go the cheapest route. replace fuel filter and add SEAFOAM to tank of premiun fuel. replace filter before 500 miles. then add SEAFOAM to gas every 3000 miles to keep lines.engine,fuel pump, and emissions systems clean, ETHANOL problem number 3000

98 Buick Regal -engine quits

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

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.

Will start then dies

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?
