Ok. So my name is Lake I have a 99 V6 3.8 mustang just a bass coop and I blew a head gasket a while back so I tore down the motor down to the block replace all the gaskets heads centers everything started up and one of the cylinders was not firing turned out it was the fuel injector stuck open on cylinder four so I replaced that I redid the wiring harness. I got everything plugged up and everything‘s nice. There’s no codes and all the fuses are good. One of them popped on me the DM I believe...

Possible short?
