i would make sure the battery terminals are tight, as well as all ground wires.
as for the speedometer, did you connect the vss at the tranny?

 

yeah the speed sensor is connected. when i rev the car the speedometer acts as if its the tach and moves up and down

 

what year civic is this?

 

its a 92 eg. i had an ls in there and everything worked fine.

are you sure you connected everything right at the distributor?

 

its an obd 2 distributor it only has one plug. the car starts and runs fine with no problems.

hmmm...this might be the rot to your problem. someone correct me if i'm wrong but i believe obd1 motors have 2 connectors at the distributor. when you say you are using a obd2 wire harness, do you mean a jumper harness at the ecu, or does that include the motor harness as well?

 

its an obd2 engine harness. i dont understand how the speedometer signal and the tachometer signal are crossed ( im assuming)

neither do i, but i do know that the tach works and is wired off of the dist. maybe that has something to do with your problem. sorry i couldn't be much help!

 

thanks. any advice is helpful. anybody have anyother suggestions

 

make sure the wiring to your cluster is correct.. and in good conditon.

 

everything worked fine when the ls was in there now i swapped in my project motor and the wires are acting like they are crossed

 

anybody have a clue about this

 

not sure but have you check'd your alt speed sensor fuse.

Yeah. Get OBD1 injectors and a distributor and wire your car properly. I guarantee it'll fix the problem.
