I am an owner of a 1997 chevy blazer with a 4.3 vortec. [:@]Ok here's my problem a few days ago my truck started having trouble accelerating.Well i took it to a place to pull the codes and it saidall my solenoids were malfunctioning. Well a few days later i got it working and now i keep blowing my transmission fuse and i can't get it out of park or get my ignition switch to the off position. Does anybody have any idea of what could cause this problem. And both the engine and transmission have been completely rebuilt and they only have around 20,000-25,000 on them.

 

Not too sure, but did you check to make sure nothing was blocking the shifter linkage?
