Main relay

Where is the so called main relay on 01 Honda Civic. Is this part
serviceable? Dealer tells me that the reason my Civic is slow to start in
hot weather is this relay and contacts in it are coming apart from the heat
under the hood. Car starts good when cold but lately it takes up to 10
seconds of cranking to start when hot, and hot means hot engine or just hot
under the hood from sitting outside. Thank you all.

 

One thing I noticed from the beginning on my 98 civic, is that
if the tank is less than 1/3 full, it takes a lot of extra
cranks to get it started. If I wait until the fuel pump
kicks off after turning the key to the on position, it
starts normally, i guess when the tank is low, it takes the fuel
pump more effort to get the fuel up to pressure?

Yes. Got a soldering iron?

You sure can tell when the hot summer weather is here.
That's when all the main relay troubles show up!

All of the previous posts I have seen about the main relay problem
relate to early '90s models. Seems odd that this problem would
re-surface on a recent model.

you should read my posts -its about 10 under your post. I have a 93 del
sol and everyone said its the main relay or the ignition switch. my car
runs fine 98% of the time but then wont start every once in a while. the
main relay is $50 from the dealer but they charge $70 to put it in. I can
let you know if it fixes my problem.
