so my power fc has no power.. the car will crank over when i put the key in and turn all my lights work.. every thing seems to be working except my power fc. i looked at all my ground also checked my fuses they all looked good so far is there any way i can test to see if i have a bad ecu or faulty wiring.. please help a brotha out before i go and just buy a new harness. the harness I'm using is not even 3 months old it was made at tech3 in san jose.. but to be honest i have my doubts about it.
thanks guys.

check the connection at the harness plug to the fc unit make sure it is tight and all the way in, sometimes the new units have a hard time mating with the old harness. put the key to on and your hand controller should light up and should have the apexi logo good luck i hope thats all it is.

you dont have a stock ecu you can try? sounds like you have it pretty much figured out. its either a bad ecu or bad harness. put your pfc on a friends car and see if it powers up. if it does then you know its a harness most likely

did you maybe check the fuel pump relay....
I have the same problem but i dont have an handheld.
My car turns on perfectly with oem ecu but not with
the power fc :werd: i opened it up ... nothing seems burned
no water damage.
any ideas?

ECU plug or the plugs by the battery Tray

Thanks , so this morning ... i woke up read this message and it hit me... i had nothing to do so opened up the apexi , connect it to my car and started measuring the wires.. I noticed the relay wasnt getting ground. I checked in the kick panel and there was a relay loose ! so my car has one relay for turning on the OEM and one for the APEXI ... is that normal ?
wel anyways everyhing primes but car wont idle so it will shut off ... maybe wrong map ? or sensor ? dont have hand held either so maybe boost controller might be on there (which should be turned off) correct me if im wrong.
here is the site :S14 ECU Pinouts (http://www.200sx.org/s14-ecu.html)
hope it helps..
