Fuel pump relay

tegger.com. main relay.

As jim beam says, classic main relay symptoms (including the trouble when hot). The cracked solder connections inside the relay assembly just seem more troublesome when hot.

Look at the pictures TeGGeR has and verify you are looking at the right relay. Dunno for sure about the Prelude, but if it was easy to find I bet it is the wrong one.

Thanks guys. Those sites make sense. I am ordering a main relay now. Actually, I plan on doing the pump and cleaning grounds, later on, as preventive maintenance for a 192k mile car.

========================

Forget the pump, unless your goal is to put 500,000 miles on the car. (even then, why not wait?) Use google (groups) to see how many Honda owners have no-start-on-hot-day problems. It's NEVER the fuel pump.

You could save yourself considerable money by resoldering it yourself. If you already have a soldering iron and electrical solder(not plumbing solder).

Repairing the relay worked great. It was faster than installing a new one since the relay could not be removed without removing the guages. I just pryed the tabs apart and removed the circuit instead of the whole thing. Sure enough, the solder joints for the coils on the relays were cracked. Not just the fuel pump relay but also the EPU relay. Funny thing is that I repaired relay boards for interphone systems in my old job. The relays themselves were what failed most often so I have lots of experience unsoldering and resoldering in new relays. This was a lot easier.

This is a very common problem. My son's car had the problem. It is caused by a bad solder joint on the relay. It can be fixed with a solder gun, once you get the darn thing out! Or, since you went to all that work, replace it.
