    Hey fellas, i have a 91 ls motor in my 91 crx. I think the ground on the thermostat housing is crappin out on me, i want to make sure its grounding properly because the car isnt starting all the time, pretty much when it feels like starting haha. My real question is, Where does that ground wire on the T-stat housing ground out to? And can i bypass it?

    Not quite sure what u mean by bypass & where does it ground out to,but its the main reference point for the ECU & grounds all the shielding on the sensitive sensors & also supplies the main relay with a ground point.

    Look after this ground point well & also the loops off the tranny & rocker cover onto the chassis.

    If your still having starting probs after cleaning these up,have a look at reflowing the solder on your main relay,or even the state of your ignition switch.

    Need a little more info/symptoms to pinpoint a starting prob.
