Mercury 500efi no fuel pressure. Help lol
I have a 500efi that’s fed by an Aeromotive pump. I’ve check the pump separate from the efi system and it functions as it should. However when I turn on my ignition the pump doesn’t kick on now. What could cause this? What should I check? Thank you for your help. I’m lost on this and I don’t want to damage the ECU by accidentally shorting something

The block is not original to the efi system. It has newer aluminum heads and a 525 cam. It’s a bit of a Frankenstein

It won’t let me post pics since I’m new, but it was definitely the fuses. The corrosion had destroyed them and the female pins in the dongle. It’s running great now. Thanks for all the advice
