A Detroit Diesel Series 60 14L came in with a severe misfire.
The ECM was replaced after injection problems were suspected. When we opened it, it was packed with water and rust.
The new ECM helped a little — but the misfire was still there. No fault codes. No injector codes. Just a straightforward misfire.
That’s when experience takes over.
A few targeted tests later, we found a shorted injector. We replaced it and the engine is now running strong and healthy.
