1998 Plymouth Neon fuel pump fuse

Hello, if that is 20 amp fuse that blows. That fuse circuit also supplies the load side of the asd relay as well as the fuel pump. The asd relay supplies voltage to the ignition coils--fuel injector/s-- 02 heater circuits. Any of those components could blow the fuse. If you retrieved a code, what was the actual code.

You might unplug the 02 sensors, see if the fuse still blows? You got to start somewhere. I guess you could use a circuit breaker on that circuit to keep from blowing all your fuses.
