Plugged my Megasquirt into the laptop. No signal. . .

Suspect that's going to be part of the issue. I'll probably spend days with the multimeter trying to discover what the hell is wrong. |

Also check you haven't been really clever like me and replaced the fuse that you are supposed to take out...
If you leave it in, it blows up a transistor and then dues weird things.

FML - I am such a 'feckin idiot. Not only was a fuse reinstalled in the St-Sign slot, it was also a 30amp one rather than the original 10amp that's there in a standard car. So that's my full injection circuit/driver in the MS2 screwed, which is why there is no power to the fuel pump. I have no recollection of installing the fuse and absolutely no clue as to why I would have ever put a 30amp in the slot. At least I now know what the problem is. . . it's me  Thanks fella. Now if you can just tell me how you fixed yours that would be great! |

Opened up my MS2 and confirmed I'm a tool. I have to say - Dimitri @ MS Labs puts these together beautifully. Even has a tell-tale.  |

I didn't have thet link that has burned out. My transistor had let the smoke out:  So i guess in theory that has acted as a fuse and saved you. I would jump that link, and i think that will solve your problem - if you tkae that fuse out. But if you do it again... it won't. Anybody else think that's a terrible idea? |

Bridged it with a single strand of copper soldered at each end. Pump now runs fine. 😊
Car still won't start though.

Anyone know what this plug is for? It's on the same branch of the loom as the coil pack connector.  |

a click may not be enough, I've had one that clicked but wouldn't give enough current to run the pump properly (low fuel pressure). ignition/timing if you do have some fuel on the plugs. cas ? also did you check the big ignition relay under the dash ? it's much bigger than the B6S8, I think it's called B577. I've ordered both B6S8 and B5S4 relays to rule them out of the equation. |
