I know there is old post for this but i have a new question, my fuse is blowing every time I put a new one in and turn the car to the on position. I have blown 13 fuses trying different things but I cant figure it out.

When I check the MPI male connectors to the ground one has 12volt the other 0 but when I touch the male connector closest to the bumper side to the positive of the battery I hear a buzzing sound.

Please help thank you. I will do step by step as you post and tell you results

Never mind I figured it out, the O2 sensor wire on engine side of plug grounding out on block. Black tape, problem solved :thumb:
 
Good job. Now find the "thread tools" link above your first post and select resolved. :thumb:
