Why is my ecm-1 fuse keep blowing and how do i fix it. Every time i turn the key to crank the motor over it blows the fuse so it wont run
Without any schematic diagram it sounds like the ECM has a short in it or something the ECM is connected to. Without a schematic for your particular car it is difficult to tell you the EXACT proble. Blown fuses means you are overloading the fused circuit. Just make sure the fuse is the correct size. Thats the best i can do with the Information i have
Good luck
SOURCE: the ECM fuse keeps blowing out
check the wiring to fuel tank something shorting. replace wires to fuel tank.

COULD BE FUEL PUMP SHORTING OUT OR PCM HAS A SHORT.
SOURCE: i have a 1990 Chevrolet C2500 Pickup. It keeps
if it is the ecm b fuse thats blowing i would try disconnecting your oil sending unit and see if it still blows the fuse.i have seen the sending unit short out internally before and blow the fuse.if it is the ecm 1 fuse it is either a chaffed wire or one of your injectors shorted.
this is for the fuel system, relay for the injector is nearly the same.
