my 88 accord lxi will start then run drives and all but when I turn it off it will not start back up. Like right now I can go outside get In her then start her right up let her run for ten minute no surging or anything then turn her off. And try to start up again it cranks. People told me it was spark because I have new wires plugs and end a coil. And distributor. I even swapped out the mail relay. Then someone said it was fuel. Problem. How will I check that?
