My 2001 Chevy Blazer (4.3-V6- 2wd) recently had a switch put in the dash as the air conditioner would not work & that fixed that issue, since then periodically not all the time when I stop and then turn to the left, the engine will die and I will blow the 15 amp ECM fuse located above the fuel pump relay in the fuse box under the hood, once I replace the fuse it will start right up until the next time it blows, any advise?

Check systems supplied by the fuse. Any driveability issues? Do an ohms test on the fuel injectors. If one injector thT has a reading that is way different than the others, you could have a faulty injector? Intermittent issues can be a pain to track down.

How long since a tune-up? Any applicable codes?
