ecm fuse blowing
 

Hello, I have a 1997 5.2 2500 ram van that keeps blowing the ecm fuse in the fuse box in the dash compartment. Let it sit a couple of hours and put a fuse in and it started. Now i can't trust it because of the possible shutdown when the fuse goes. So i was wondering if anyone out there has had a similar problem and how it was corrected. Thx in advance.

Perhaps your ECM is internally shorted.
