put in a walbro 255 but forgot to take off the battery when i did it. now the car cranks but it doesnt prime the fuel pump. i dont know if i messed up a fuse for the fuel pump. where is it located.

 

If that little black cap that attaches to the bottom of the pump is slightly off, mainly from taping it while install, the car will do this. After you put everything back together tightly make sure you don't hit the assembly against the car when re-installing.

 

You plugged the harness in right?
