I have a 95 hatch with a b16a2 swap. My fuel pump dosent work i am not getting any spark. Also i checked the TPS sensor. for voltage but there is no voltage. There should be 5V but there is only 1.23V. The same things with the MAP sensor. I checked all the fuses and the relays too. I think my ECU is not grouned or it's not getting any power. Does anyone know which wire is for the ecu power and the ground???

 

Check to make sure you have good gorunds on the trany and the motor side from the chassis

and the wires on your ECU should be,

A25 and B1 = 12v
A23 and A24 = ground

 

There good, where is ther ground located for the ecu?

How can i check a25 ,b1,a23, and a24?

 

With a Volt meter and your key

 

Thanks!!!
