Do any of you MegaSquirt users know of settings in MS that control the fuel pump?
It seems as if my fuel pump doesn't come on when it should. (the wiring is correct, I KNOW it isn't wiring, the board doesn't have any boviously visible trace issues, we have checked continuity through the whole system and it is either hardware issue or software) direct question: which settings for the MS will cause fuel pump issues? |

Do yourself a favor and bypass the MS circuit entirely wire it so your fuel pump runs constant while the key is switched on.
This way you can get it running/started and then workout the bugs. I found this easer, like I said I eventually went back so my hall sensor signal activated it and etc but short term it was fine with fuel being pumped while the key was on and it not running. the injectosr being electric will nto open or leak unless they are damaged. |

I have alligator clips by passing the MS right now... lol while I'm looking for an answer to my question. =o) |
