EFI Fuse blew
2 Days ago my 15a EFI fuse blew on the highway and my '95 ES shut down. I got a tow to my mechanic only to find out that it was one little fuse. With a new fuse in place, I have driven about 15 miles so far without any problems.
I checked the wiring on all 3 o2 sensors and they all seem fine. I can't find any other obviously damaged wires. I find it hard to believe that it was a one time fluke, but i cant find any other problems, and neither could my mechanic.
The EFI fuse also has the ECU and fuel pump in its line, so im worried that it may be the pump, but i dont know how to diagnose it.
