Yesterday my car refused to start-it cranked but didn't even pretend to fire.
This morning I found that the main relay was inop. I found a Spider relay Bosch 30A with the same pin configuration, tested it successfully and stuck it in the LS. It fired instantly!
Here's the question:
Bad LS relay was a Bosch 0332014112. The good relay is a Bosch 0332014125. The only difference is that the good one has a mounting tab. I'm guessing they are identical otherwise.
Now I'm going to open the bad one to see what's going on.
Should I spring for a new relay or use one of the old ones (if I can tune 'em back up)?
It's the fuel pump relay with 3A fuse. My Spider sheet calls it a "main relay" I just opened my bad one and found a fried diode and coil. I'm going to pull the working spare out of the car and see if it has a diode or not. If not, I'm getting a new one.
