ok.. here is he deal my buddy has a 94 hach dx ... when he got the car the guy b4 him did a wire tuck his heat hand and gas hand wrk but his tach and speedo doesnt he is using a gsr harness... he has swapped ecus,cluster,and speed sensors i kno they work because they came from my car so wat could b our problem... plz help it is driving me crazy tryn find the answer

 

not trying to sound like an a$$ but obviously going to be wiring, start at the vss and trace the wires back all the way to the cluster checking for breaks corrosion and pins in the right location do the same for the tach.

 

Is it throwing CEL code 17 by any chance?

Easy thing to do that has helped me in the past is to clean the VSS terminals and its connector too, even if they look clean.

If that doesn't work, do you have access to a multimeter or a voltmeter? Check for continuity of the VSS wiring. A cheap Hayne's manual outlines the rest of the VSS check procedure.

 

My tach wasn't working properly in my 98 civic ended up being a bad ground

 

yea i checked the ground it was a slip on kinda ground and i dont have a multimeter and i hate wiring..lol but i will clan the connectors..thanx for help

 

Or you could just run a new wire to the tach from the blue wire on your ecu. You have to splice into it and you can't cut it !!! 96-04 civics the speedometer wire from ecu is blue/white, not sure about 94 or gsr swap whatever you have.

 

what ground was it?
