Keeps blowing electronic controlmodule FUSE?

\015 The ECMB fuse keeps blowing. I hear that this could be the fule pump or the control module. Where is the fule pump on a 91 S 10? Where is the control module? How do I test to find out which one is the problem? \015\012Thank you in advance for your help. Bob\015 Posted / edited by AnonymousUser on : 19-03-2018

Answers :

I have seen this many times in my 30 years as a technician, it is always caused by a shorted engine wiring harness, look around the harness in area's of wear, like where it connects to the engine from the firewall or where is crosses metal like cylinder heads, it will be rubbed through somewhere.
