    are you sure the fuel pump is ok? it sounds to me that it ran out of gas. and usually its the pump or the fuse relay to the pump. if not check filter andi think you did that. my other guess is that your injectors are getting pluged up. there should be a small release valve on the fuel rail where u can check if the pump is getting the gas into the rail. or at least i know my 2.8L engine has that.

I agree. that's preety much all there is to the fuel system. All fuel rails have the release valve. If you could get your hands on fuel pressure tester, that would be helpful. Also have someone stand by tank and listen to see if they hear the pump kick on when you turn car to on position

Hard Start When Cold 01 Bucik Regal

Did you check the fuel pump relay ?
You would need to use a fuel pressure gauge and check pressure before you crank the engine.
When you turn the key switch on, the pump relay is supposed to provide power for 3 seconds to boost fuel pressure.
If fuel pressure is ok, the coolant temp sensor could be telling the computer the engine is warmer than it really is.

My lights all come on but my car won't turn over doesn't make a sound or anything. What could the problem be?

I had a similar situation just this weekend on my 94 Buick Regal GS - it was the fuel pump (it wasn't 'engaging'). Unfortunately it was labor intensive (the fuel pump is in the gas tank, so they have to drop it to get to it), so about 500 bucks later, I have a new fuel pump, fuel filter (and, oh yea - a new battery, too just for fun).

My 1999 Buick regal will start but within in a minute it will no longer run. All lights work and radio. It will not keep running almost as if it is flooded.

It sounds like a fuel pump resister. I had exact same problem with my regal, resistor has 2 black leads, ceramic and it shapes like horse shoe. mine cost $79.95. Before I know this, I had the dealer replaced fuel pump, fuel filter still didn't fix the problem, and they suggested injector madulator. Very fortunate I ran into a friend has the same 1999 buick regal V6 SC and had same problem told me about this fix. I called 4 buick dealership parts dept.and asked to buy a fuel pump resistor they all told me that there no such thing! So, if want this p[art go to GM parts dealership.
And ask them to show you where it locates. Because it hidden inside engine compartment.

Hope it'll fix your problem like it did mine.

My 1998 Buick Regal does not start on incline (when the front end is raised). It turns over but will not catch. I have to roll it to level spot, wait, then--with much gas peddle pumping--it starts. What...

My guess is a fuel pump problem. Most cars today are fitted with two pumps, a pre-pump usually within the tank and a second main pump further towards the engine under the floor. ONe pump matbe enough to keep the car running but under additional strain such as pumping fuel uphill this can overwhelm the lone pump. Locate the fuel pump fuses and relays and ensure that they are OK. Now remove the filler cap and have a friend turn the ignition to position 2 (not starting the engine) you should be able to hear the buzzing of the pre-pump if put your ear to the filler pipe, do this in quiet area. Remove the pre-pump fuse and listen again for any contrast in sound level. If there is no change then the pre-pump needs to be renewed. Do the same to the second pump fuse, although this time the noise will come from mid position along the car. When you renew one or other of the pumps also take the opportunity to renew the in-line fuel filter, any slight blockage can make the difference between a car that is easy to start and one that is very hard to start

2000 buick regal hard to start

if this car is been sitting, the battery might be low or dead, but if not,
you know your question confuse me a little be, because if your car won't turn, that has nothing to do with the filter, but if the car crank but wont start then it migh be a bad fuel pump, the way to fin that is, by aplying some flamable brake or carburetor cleaner to the intake, then if the car starts or try to, most likelly your fuel pump is gone.
