    In my 87 Blazer, 350 TBI, the ECM fuse (for the fuel pump circuit) keeps blowing (4x in the last few months), which stalls the engine at the most in opportune times....... I looked at the wires running along the drivers side frame rail back to the fuel tank. I did find one wire that was exposed, fixed that. But then it blew the fuse again today. Anything like this happen to anyone else? Any ideas? Should I look for more bad spots in the wires? Any thoughts would be great.

    My guess would be to check right where the line go up to the top of the fuel tank. My blazer had the fuel gauge sender wire broken there. It is kinda easy to get them pinched up there when replacing the fuel pump. Unfortuently you may need to drop the tank to find the problem.
