I have a fully built 94LS motor in my 91 hatch and i hooked up my new ECU and not my car wont start.....the motor turns over but i hear a clicking under my dash, im gettin fuel. Could a bad ECU cause this problem? please help gotta take my turbo baby to the dyno soon.

 

Is the clicking coming from above your left foot? That's the main relay. They go bad all the time, about $60 from honda. Only use an OEM honda part.

 

Be sure to check all your engine grounds also

 

Dont buy a new relay just yet. Check your engine grounds mainly the thermostat ground. Also check to make sure both harness plugs on the passenger side are tight.

 

thanks guys...got it figured out...my jumper harness wasnt plugged in tight enough..

Thanks for all your help
