Had a guy contact me today, he has a 2003 Mitsubishi Fuso with 4D34 engine.
The ecm numbers are: MK369413 407914-3920
Originally the vehicle would stop running, he would replace the ecm fuse and it would start again. At one point it wouldn't start even with a new fuse so he bought another ecm for a "few hundred" dollars .. but forgot to ground the ecm strap and fried that one.
I want to suggest that he just send the "original ecm" to a repair shop but don't know of a reputable ecm repair shop...can anyone help?
