Hi,

I'm having a problem with my 93 Prelude S.

When the weather is hot, for soem reason the car will not start. But when it's cool, it starts fine.

The Car cranks, but does not want to start.

Does anyone have any suggestions on what to do.

Thanks in Advance

 

im having the same issue seems in hot weather it radomly doesnt start. Do you have any mods, might be able to pin down the source if we compare a few things.

 

lol same problem....someone told me its the main relay they were made like ****...in the heat the wires expand and crack. Try banging the drivers side dash by the a/c vent a couple times and try it again. I need to get me a new relay but thats what seems to be the problem.

no relay=no power to fuel pump=no fuel=no start

 

definitely the main relay - go to honda and pick one up. It's located under the dash in the driver footwell. Crawl down there and look up by where your left foot would be and you should see a little box. Pop the old part out and put the new one in. I'm sure this has been covered a million times so search if you need further instructions.

 

If it doesn't end up being the main relay, i could also be the ignitor.

 

didn't even read the thred,

first thinkthat comes to mind is main relay, all i saw was the word weather/.

 

yeah, another common problem with the 92-93 preludes is the ignition module, i also had to replace that.
