Fuse blowing
My 97 454 burb suddenly cut out when driving, leave it for a while and it would start up again for a few more miles and then cut out again. Now it is blowing a 20 amp fuse that is for the ECM-B. When it blows it stops the power to the fuel pump relay. Now it won't go at all as the fuse blows every time I try it.
What is the ECM-B anyway and can it short out to blow fuses or is it a wire that is arcing to earth. Any help much appreciated.
