1991 Buick Regal 6 cyl Front Wheel Drive Automatic 150000 miles
----------------------------------------------------------------
I have a 1991 Buick Regal Custom 3.1L engine. Now my problem is I was driving and went over rail road tracks and my car sputtered and then shut off. I started it back up and it sputtered still when a little bit further and shut off again. Since then I cant get the car to fire up. My fuel pump is good. I have spark. I have good compression. My crankshaft sensor has been replaced. All my fuses have been check, yet I still cant get it to start. Now if I spray starting fluid into the intake it will start and run off that for like a second. So I was trying to figure out what tells the computer to fire the injectors cause that’s what I think is not happening. Please help Ive been trying to figure it out for like a week now[/quote:74830e68f5]
