Problem with Power FC in ECR33

[Jore]

Hi,

I have ECR33 Skyline and when we put PFC in and power on, fuel pump relay starts to click continuosly. Also "check engine" and some "katalysator preheater(?)" lights go on in dashboard. We have checked that ecu gets the 12v (somebody has had problems with this) and we have tryed to install it several times. When I take PFC off and put back the original ecu, the car works fine.

Any ideas to test?

I have read that,

there is a very common issue with the PowerFc.

The PowerFC draws more current then the standard supply line can carry.

Once you upgrade the 12V supply to the ECU it will work no dramas.

If you run a search, im sure it would be covered on this forum.

If the fuel pump relay is the only problem, i'd be inclined to wire the trigger directly off the ignition switch rather than try and rewire the ecu power feeds.

The r33 has a power plug in the front passenger corner that should give you a swtched ignition source, splice a wire in and run it across to the fuse box to trigger your relay and youre done.

you shouldnt hardwire the fuel pump.

Letting the ECU control it is best. Just running a bigger wire to the pump solves that problem from memory
