I installed the battery backwards in my 1994 280 EXT with EFI. As soon as I did the fuel pump started running even with the key turned off. I then realized the problem and properly connected the battery but now I don't have spark? I check the fuses in the fuse box. The 3 amp EFI fuse was blown but all others are ok. What could be the problem? Is there an inline fuse somewhere?
