So I have a problem. I was driving my gs300 and It was working perfectly fine and driving no issues at all I stopped at a gas station and when I tried to start the car it would crank and everything I checked air fuel and spark and there’s no spark so I checked the fuses and the efi fuse blew. I replaced it and it blew again I did it like 3 times and the car didn’t start so I removed the efi relay and the efi fuse didn’t blow so I don’t know what the problem is all the grounds seem to be connected any suggestions will help.

 

Have you tried replacing the relay you removed with a new one?
