Honda Car Forum

Hi,
I have a 93 Accord and I am having a hard time starting it if has been left
in the sun. It seems to vapor lock, a little Starting Fluid and it runs
fine. I have changed the gas cap, air filter, and fuel filter. Does anyone
have any suggestions? Also when I changed the fuel filter when I bled the
fuel pressure on the fuel rail there was no pressure( If that makes any
sense).

Thanks Steve

One strong possibility:
Early 90s Hondas are famous for failing to start after being left in the sun.
The cause is often a main fuel relay failure. The following describes the
problem and a fix for it.

Note that the photos won't be dead-on for your Accord, but they should be close.

My 1991 Honda Civic's original main relay became a problem like the one you
describe in 1999. I didn't bother trying to re-solder, but many people do. I
just replaced the whole relay. I used an online parts site hparts.com (I think
it's out of business now) to get the part, paying a $38 altogether.

The main relay was tough to get too but I and many other people have managed it.

I think others have posted other online resources for the main fuel relay
problem, so keep checking back for more info.

Caroline's dead right on. I had this problem over a year back in my 92
Accord. Got a new main relay and that fixed it.

MAIN RELAY!!!! :-)

It's such a common problem... My friend had it before and then we vented the
relay (literally taking the relay out, drilling hole's into the casing,
putting it back) this allows the relay to cool. The other option is to
replace the relay. they can be expensive, depending on where you go. Don't
get one from a junk yard, no telling whether or not it has the same problem.

The cheapest solution - Get into the car. Open the windows, let the car air
out for a couple of minutes. It will start. Or it's a simple as knowing
where the relay is and tapping it with your foot and the jolt will get it
back into place.

Find a tech that knows how to solder the connections, and your troubles
are over. My guy charges fifty bucks for the whole job. bob

Thanks to all of you . the problem is solved just bad solder in the relay.
