Fuel pump priming issues after installing ms3mini
I saw another forum about this but I am extremely lost and would really appreciate help. I just installed an ms3mini, basically an ms3. I haven't messed with the fuel pump or anything in the fuel system. When the key is turned to the on position, the fuel pump is meant to prime for two seconds, except mine won't stop priming. Any ideas? Thank you

The only wiring I did was installing a Wideband. I did tap into the door buzzer wire because its an ignition on power source, could that possibly cause an issue?

Switching the fuel pump jumper may do the trick. Its on the MS3 Mini board

my bad for not saying what it was, 1.8 1995. Anyways I solved my issue. ms3 minis don't come in a case, so you have to use the old ecu case. Well one of the pins for the fuel pump was touching bare metal... grounded to the chassis... making the fuel pump continuously pump.
