Not Turning Over After Walbro 255 installed

[markgholland]

I was wondering if anyone could possibly know why my car isn't starting/turning over after I put in a Walbro 255 fuel pump, sending unit, and the assembly. It was turning over fine before I gave it power, but I remembered that I forgot to make the connection. When it was connected, it was turning over, but slower than before and then it just stopped. If anyone could help me out, that would be great.

Sure sonds like you shorted a 12volt wire. Check the harness near the pump. Its also possible that the pump motor has a short inside it.
