Did you just put this together? What did you do, tie your ECM power into the interior lighting? :lol:

Re: 92 tpi enging shut down

is this a spam bot? If not I'm going to guess you are missing the ground strap from the body to the engine. The load of the interior lights is pushing your electrical potential on the ECU below its threshold. (or about 1000 other possible ground issues) Does engaging the headlights or power windows also shut it down? If not you may have accidentally used the interior light circuit as your ground, it will ohm to ground because of how incandescent bulbs work.
