i cant get power to my euc in my 91 crx si with b16a1 swap. i instaled air/fuel and it was fine and then went to start and it wouldnt start so i check wiring and theres power to the fues bo xin engin ebay and the grounds are grounded but theres no ecu power.

 

If the A/F guage was the last thing you did before it stopped running, then disconnect it, you may have it wire wrong and are short circuiting something.

Are you checking for ECU power with the ECu plugged in? Try unplugging the ECU then checking the power and ground which go to it for power. This will determine if the problem is at your ECU.

 

Check your alternater fuse in the inside fuse box.

 

ya i'm check this and umm the alt. fuse was it. but we found it before you posted.

Thanx guys
