R33 gtst power fc problem

[croat]

installed my power fc into my r33 and have had some wierd problems. The power fc unit itself is fine as i have tried it in other gtst's and all works fine. when i fit it to my car all is ok at first, when i go to start it the car just cranks over and wont fire up. then a relay switch in my boot keeps flickering on and off. Also as long as ignition is on my bosch 044 fuel pump wont shut off at all, which it is supposed to stop after like 5-10 sec's. This has got many people biting their nails...

Does anyone know what it could be?

Sounds like either, you havent turned off the boost controller kit on the fc, which is stopping the car starting. Or you have a problem with the wiring loom in your 33.

I had a similar problem, which turned out to be the wiring. The stock ECU ran fine, As soon as I installed the FC, turn the igniton on and the relay switch in the boot would go crazy.

Check the voltage at the power fc and it was only 7volts. I had to re-run a new 12 volts line from the batter up-to the ecu harness. and it worked fine.

See how you go.

If the fuel pump is still running.

obviously the ECU is not controlling it. So follow the wires from the fuel pump and make sure they lead to the ECU and not ignition

r32 nismoid yeah i get what you mean, but the standard ecu controlls the fuel pump fine, so i dont think there are any problems with the wiring? also i have a apexi RSM and HKS turbo timer tapped into my loom... Can this work in accordance with the power fc?

BBQ yeah ill give that a go.
