Re: Blowing ECM fuse

Depending on the year, it is mounted on the passenger side firewall. The FP relay socket will have a 4" red wire pigtail with a spade lug. With ignition off, you can apply +12votls from a fused source to the pigtail to power up FP - this can be used for priming or pressure testing fuel system.
