Strange looking. Can't see if the damage extends to innards of the 
relay. Could be just a soldering iron having brushed over the relay 
enclosure. I'd be more interested in copper traces on the PCB to the 
relay. Corrosion? Typically the copper traces are covered by a 
protective film except where components are soldered to them. You could 
try to clean the area with alcohol and inspect closely.

But, yes, could be the problem. I think those relays are for the injectors.

Pulled the board out to swap back and got a light to check solder joints for possible cracks and found this relay with a chunk of plastic missing which doesn’t look normal to my untrained eyes.  Could this possibly cause my issue?  I assume a relay of done type is used to switch from A to B and back…?  Thx
