Check the code by looking at the blinks of the computer under the passenger seat with the key on. To clear the codes take the ALT.SENSE fuse (7.5 A) out of the box to the rear of the battery. I have had the front O2 sensor go out and the light would go on when I was going over a mountain pass.

Can the engine of the 1993 Legend fit the 1990 Legend and vise versa?


Sure, just might be a few cosmetic differences - as long as they're same engine size.

When the car is hot, and you turn the key, the check engine light goes out, but the car will not start. The fuel pump has been changed, but the problem is still there. What should we do?


It is your main relay. Go to Youtube and search acura legend main relay. The main relay is located by your feet above the steering column. The solder point in the relay are weak due to temperature in the car while sitting and the outside temp is high. Also do a google search. several schematics on location. I would tap mine while turning the key and it would fire right up. Best solution is to remove and resolder the joints that are bad. Visually you will know.
