How do you change a fuel pump or check rely on an 87 Honda CRX si?

Answer 1

Not sure if it is the same as a 1990 crx but the fuel pump is in the gas tank. You will have to drop it and it is on the top side. As for relay a good way to test it is turn the key until all the different lights come on in the dash.

Let it stay on and see if the engine lights goes off or stays on. If goes off the relay is good if not then you need to replace. I had this problem w/my 90 rex and that is how I determined it was the relay switch. Have not had a problem since. That was over 3 yrs ago.
