Re: Fuse Keeps Blowing
Could be the oil pressure sending unit. Try unplugging the sending unit & see if the fuse blows. PCM also monitors the pressure so I'm not sure if the engine will run without it plugged in. If it won't run without the sending unit plugged in then you'll need to replace it in order to rule out an internal short in the unit.
Fuel injectors are also on the same fuse so if the pressure unit checks out you'll need to look at these next.
