So i was driving my 01 civic all day when I stopped to put gas. I always fill up at the same gas station. Drove it the rest of the day just fine. Later that night I went to Lowes. Drove fine. When I came out it didn't want to crank. It was puttputting. Some guy told me it sounded like I had bad gasoline. Finally I got it to start but it kept trying to bog down and die on me. I got it home cleaned the plugs and now it doesn't even wanna turn over. Checked the fuel pump. I have fuel coming out of the tank to the front of the car. I have fuel going to the plugs. I put new plugs and no change. Maybe fuel regulator? If so, I have a adjustable fuel pressure regulator. How would I bypass the factory regulator. Need help fast !!!!!!
