frikin relay

i changed my main relay last month and the frikin thing already stopped workin right, i bought brand new from a parts store to, anyone else have a problem with a newer main relay goin bad

that's weird...I wonder what's frying it? you have the proper fuses in?

i think the heat did it casue i went on a 2 hour trip to my frinds house yesterday and it was like 90 degrees out and when i got there i turned of the car wwalked inside to see if he was at werk but he wasnt and i went to start it up and it didnt start waited for like 20 minutes and it started, so i duno ill check the fuse then see ifs theres a warranty on it or sometin

what does the main relay do? like...if it's not working, does the car make the rrr-rrr-rrr noise when trying to start up?

the main relay swithches on the fuel pump and the fuel injectors. the car turns over but just wont fire when it goes bad
