Fuel pump problem SC 400 codes 13, 21, 78
Just recently replaced my 1992 sc400 fuel pump and the car started up on the first try, however the fuel gauge did not work. It has been 4 months since and I have put less than 100 miles on the car. I did notice that the fuel pump was not the exact one that I took off. This morning the car would not start I changed the electronic box on the passenger side of the car, no luck. I did the by pass, no luck. Check my codes and I am getting 13 RPM signal, 21 main 02 and heater signal, and 78 fuel pump control. Did I not only get the wrong pump but a failing one? Help any suggestion will be appreciated.
