So, I am now having the wonderful "mystery no start" with my car on a super hot day.

I did a little research on here and all roads lead to the Fuel Pump Relay.

So here is the project:

Now, from what I've read, the point of failure appears to be the solder points on the board due to prolonged exposure to heat. If this is the case, I have access to many people with over 30 years experience with industrial and enterprise electric applications and we'd like to see if we can re-solder the contacts with a higher tolerance material.

Unless the relay is solid state, myself and a few buddies would like to take a look at a bad one and see where the point of failure is and possibly fix it or even better; make a new one on the cheaper.

Soooo...

Here's what I need:
A broken relay module - I will pay for the shipping to me. If it works, I'll ship it back on my dime, you get a working/upgraded one. If it doesn't work (we can't fix it), I'll throw it away or ship it back to you. I only need one because my car is my main and I can't have it down.

Second thing I need: info - any confirmation that my understanding is correct, info on what the engine bay temp is under "normal" conditions, etc.
