Hi, I have a 1998 LS Chevy Blazer LS, 4door, 2WD. I can't start it because it burn fuse ecm1. I have a short but where? I need some help!!!!!

 

Oh boy, you're in for a project.
Finding shorts can be ridiculous.

First start from where its burning the fuse & trace them wires inch by inch. That includes all the connectors & pins. Look for splits, corrosion, anything out of the ordinary. Had the same problem w/ my Dakota. The fuse that supplied power to the diag connector under the dash kept popping. Of course everything of these older years are prone to corrosion & my problem was of no exception.

Secondly, it is possible but unlikely that you've got a power surge going on. Check to see if any other fuses are snapping.

Lastly, make sure you don't have any wires crossing or pinching.

I know this tip is vague but finding shorts will spin you into a dimension off pissed off you don't want. That is the way it is. Good Luck Buddy

 

Thank, I'll try to be patient. jejejejejeje
