MY 2000 Honda makes a slight noise when it goes up hill...?
Yes it can run, a check you can do. disconnect the connector that goes to one of the throttle body's, one is a plus and minus. Do this with the key on or while cranking the engine and it will probably run. The throttle body modules get the signal to pulse, how long etc from your computer, that is probably what is crapped out. The same thing, same symptoms happened to me on a Pontiac Fiero, changed the computer module and I was back running again. However I was able to capture a code that indicated the problem. there are about a hundred pins in and out of the computer, only one is the inj. mod control. Good Luck.Before you go and start replacing expensive parts, check fuel flow and pressure.
One of my struts is leaking. Should I replace just that one or all four?
Could be pump relay, oil pressure switch, or bad pump ground wire to frame, or fuse.
