Re: 97 sub blows fuse ecm b with fpump relay removed

glad to hear from you steve. I had read some of your other posts and was hoping to hear from you or old dave I think his name was. I just got back to my computer. I think I just finished doing some of what you described, although I think I did it the long way. In this order, I disconnected the fuel pump relay - install fuse & it blows / disconnected the connecter at the fuel tank (3 prong .....I believe it would be the right one...it's coming from the top of the tank..... gnd*pump*fuel gauge... I would guess) - install fuse & it blows / unplugged all 5 connectors from the PCM - install fuse & it blows.
Reconnected all of the above and came back in to check AF.

So, I would assume at this point its not the fuel pump circuit past the pump connector or the PCM. Is this correct? If so what the hell's next outside of needle and haystack scenario. I am remembering that this is why I decided to start flying airplanes instead of wrenching on them. Thanks MG
