My CRX with b16a started acting really wierd all of sudden. The tachometer stopped working, the temp guage stop working and the engine started to surge at low thorttle/low rpm. Then all of sudden whenever I turn the key to the on position the main relay clicks really fast and never powers up all the way so my fuel pump doesnt come on and I cant start the car. I tried a brand new relay and it still does it. Any ideas?

 

So far form searching Ive checked, thermostat ground (sanded and redid connectors), Valve cover to body grounds, tranny round, and battery to body ground. I found a bad fuse for the condesor fan bad I dont think that will cause it.

 

I tested the connector to the main relay to the wire going to the thermostat ground and it didnt come back to good. I shoved a wire into the back of the connector and gounded it and it stoped doing it. But my tach, temp guage and eacv still dont work, I wonder if they are on that thermo. ground too? Can I just relocate that whoel ground?
