Going to try to keep this as short as possible. Recently I replaced my fuel pump with an aem 320 e85 version. All was fine for about 2 weeks then all of a sudden starting blowing the 20 amp fuse that's located at the bottom of the pic I've attached. It's located between the yellow 20 amp and the red 10amp at the bottom.

Side note right now the slot where the blown fuse goes is empty because I pulled it out. I think it's the mfi fuse but I could be wrong on that.

 

did you check your battery?

 

there might be a shortage of wire

 

I'm figuring there is a short somewhere because at first the 20amp fuse would last and now it blew a 30amp. What I'm wondering is if my cam angle sensor could cause that fuse to blow since my exhaust manifold melted the wire and sensor a little while back. I'm having trouble finding a wiring diagram tho and don't know if it's part of that circuit or not

 

I found out what's in the system. Going to look for frayed wires and go from there.

Fuse 22: Engine Control Module, EVAP Solenoid, Exhaust Oil Feeder Control Valve, Heated O2 Sensor 1 and 2, Injectors 1-4, Intake Oil Feeder Control Valve, MAF Sensor, Throttle Actuator Motor Control Relay, Turbo Wastegate Solenoid 1 and 2.

 

Pretty sure the cause of this is going to be the o2 sensor. Won't know for sure until tomorrow. I'll update once I have a for sure answer
