Chevrolet Repair: S-10 blazer / ECM B fuse, fuse block, jumper wire

Question
I have a 92' S-10 blazer , Vortec V-6 .  Recently  the electronic control module, fuel pump fuse in the fuse block has been blowing. The fuel pump was replaced less than two years ago. At first it would just blow after a start or two on every fuse , but now after doing a tune up it blows after a min. to a few min. after start up. What are the most likely causes for this problem? Thankyou for any help you could provide.

Answer
Hi Jeff, I'm sure on the wiring system but the fuel pump could be your problem. When a fuse blows after a minute or 2, it is a high amp load and not a short to ground. This would lead to a componant that runs, as in a motor. I would locate the fuel pump circuit and power it up with a fused jumper wire to see if the pump blows that fuse.
