2002 buick regal has trouble starting

Check the connections and have the battery tested. The other components (starter & alternator) can also be tested.

could be the starter solenoid is going south or also an ignition could be a culprit. try to duplicate the condition and gently tap the side of the starter with a hammer while someone else holds the key over in the start position. be careful while doing this. if the starter turns when you tap it, the brushes inside the starter itself are gone and the starter needs replacing.

have a load test done on the battery for failing cell and have the output of the alternator checked as if the battery is faulty then the alternator has trouble supplying enough current to run every thing electrical

check all your fuses and your coil/coils, could be your alternator. check your distributor cap also, points, tightness, etc.

Was the old battery in fact,tested and proven in need of replacement? Does the starter solenoid click?

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.

did u have ur starter checked?

when it doesnt start check for fuel, may have fuel pump or relay going bad.

Check to see if your alternator is charging. You can do this by having the vehicle jump started or with a borrowed battery. while the vehicle is idling, remove the pos battery pole.. if it cuts off .. then ypur alternator is bad or the charging circuit ( like a break in the line or fuse etc.)
