I have a 89 buick regal coustome it wont start and when it does it dies a few minuts after. can someone help me please?


you may have a fuel pressure problem.it should be checked with a gage and it should be about 35lbs pressure and also have the volume checked as you could have good pressure but not good volume.this sounds like fuel problem.

1989 buick regal 2.8 stalls out. it will start and run well for 5 seconds and then just die. it starts better with a spark plug disconnected. fuel pressure is 40lbs. plenty of spark from coils. replaced...


The catalytic converter maybe clogged. This would result in a car starting then cutting off. you can unbolt the catalytic converter see if that solve the problem. Then if that was the problem replace it with a new one. Goodluck.

Buick regal 3.1 new battery new fuel filter won't start


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
