Help: '90 Accord

Our '90 Accord won't run. it stopped on my wife a week ago, had it towed to
a service place. They couldn't find anything wrong. Our mechanic said it
was probably the fuel pump relay, and if it went again it would have to be
replaced.

Now it's in our yard. I have a Chilton manual from the library, but it's
not real clear on the "main relay". It does say it runs the fuel pump which
is in the tank. It says the relay is above and behind the fuse box. I
can't find that relay! I stood on my head under the dash, and there are
several boxes around the fuse box, but I can't find one which has the
contacts shown in Chilton.

Any advice? Hate to have it towed to the mechanic just to change a relay!

 

If you have cruise, it's hidden behind that box.

 

I have had to replace the relay on my 90 integra, so I'll describe where it
is on my car. In order to see it without taking off the dash, you're going
to have to lie flat on your back and put your head over by the pedals. You
should now be looking straigt up at the steering column. You will see the
bottom of the relay (with a wire connecter and associated wires going
straight up into it) to the right (driver side) of the steering column.
Mine was brownish. If that doesnt work, take off the left lower dash panel
and you should be able to see it without having to turn upside down and
around.

I had the same problem and had no spark. But 3 days later the spark came
back. and it started and never happened again. I dont believe it's a relay
problem in my case, but for you, it's worth a try.

I did a web search at Northernlights.com and found this website that talks
about your car's relay.

Thanks for the help! Great advice!

 

Heres a link to a great site to fix a main relay. It helped me
tremendously when I had the problem with my '91 Accord.
The cracked soldier joint was very hard to spot. Even when
knowing exactly what to look for. Mine was just a little mark on
one post (didn't look like even a crack). When un-soldiering this
joint the soldier melted differently than the other joints.
