Asked by Jul 30, 2017 at 03:35 PM about the 1999 GMC Suburban K2500 SLT 4WD

Question type: Maintenance & Repair

I have a 99 gmc suburban that pops the ecm fuse as soon as i turn the
ignition. Now this happened once before with the same vehicle because of a
pot hole that i couldnt avoid. I checked every fuse, fusable link, and wire
connection from front to back without any luck. I pulled the battery out and
closed the hood. 3Weeks later i needed transportation for work so i took a
chance and put the battery back in and it fired right up. Here it is 4months later
and it did it again . Why is this happening ?
