    My 97 Buick Regal does the same thing, but the temperature does not have to be sub-zero, it has only dipped into the single digits here. It will start but the idol will start falling as if it's running out of gas. Yes, the fuel pump is doing its job, already checked that. The battery is good. I'm thinking maybe a sensor is bad or going bad (but if it is the cars computer is not showing anything), cause when its drove on the highway it will do this sometimes and it wasn't cold when it did that. Also having problems with front wheel ball bearings wearing out just replaced both sides less than a year ago. Anyone else having problems with that?

    My car finally threw a code, plug 4 misfire, but the plug and wire are good. Last summer it threw a code for the mass air flow sensor, so I bought a can of mass air flow sensor cleaner and sprayed the sensor.
    Guess what, it worked. All of the other things: hesitation, bogging down and the not wanting to idol-- all of it straightened up. But I still have trouble with the front wheel ball bearings.

    Can you hear the fuel pump engaging when you try to start it?

I would take a listen by your fuel filler door and see if you can hear it engage when you turn the key into the "ON" position. You will need someone inside the car to turn the key, and another person by the fuel door to do the listening. If you don't hear the pump engaging, you have a problem with your fuel pump. It is either bad, or not getting enough of a connection. Nine times out of Ten the fuel pump is bad and needs to be replaced.

Hope this helps you out.

When my 94 Regal GS frequently wouldn't start for 30 minutes to an hour after being driven, it was the crankshaft positioning sensor that needed to be replaced. I also replaced the harmonic balance pulley. The car ran more smoothly and started everytime.

My buick regal 2003 wont excelerate it starts


It may be the throttle position sensor. You should have a check engine light on in your dash. You will need to have someone plug a OBD II reader in and retrieve the code.
You can spend a LOT of money just putting in one part after another.
Please let me know what you find.

the electric cooling fan for the radiator will not turn on when the engine reaches normal operating temp, its only supposed to come on if the engine temp goes over the normal temp. (around 220 degrees)
it is normal for the fan to come on any time the a/c or defroster is turned on.
