Ever since i got my 1992 si lude when i leave it in the sun it wont start and every time i turn it off and come back 3 minutes later it wont start. It just turns over but wont fire up. Its so weird. Does anyone have a clue whats wrong here. Please.

 

Probably main relay

 

my guess too.

if hot weather is affecting it, then more than like it is that main (fuel) relay

 

thanks but if that not it what else could it possibly be?

 

main relay.

 

i have a similar problem with my 98 base prelude. my car starts, but it has a hard time starting. i always thought it was a fuel problem. why do you guys think it would be a main relay?

 

Main relay, VERY well known and common problem. Pull it out and resolder the contacts. With temperature changes the contacts expand / contract and can break.

...i also had a 92 si before the swap and had the same problem ...when i left my car in the sun for a long time and tried to turn it on it would crank but not start for like 10 mins...i heard it might be the MAIN RELAY so i bought a new one and never had that problem again

dont be surprised if you break your back trying to get to it tho

 

Had the same problem with my first 92 lude. Main relay was the culprit.

 

were is the main relay on prelude.

 

It way up under the dash above the steering column. PITA to get to.
