Power Fc Help! Wont Start

[45LDE]

Iv just put a Power FC ap engineering ECU on a r32 with a rb20det and the car wont start. The Fuel pump does not turn on and the hand controller will not turn on.

But if i put the stock ECU in it works and the fuel pump will turn on.

Any ideas????

Thanks

what's the product code? someone on here can tell you if that pfc suits your car? and did you buy it new or s/h?

its the right one, iv opened it up and it says rb20det, and its been seen running in another car over a year ago.

iv got a feeling its been fried?

Thats exactly what my one did when I fried it (put the battery terminals on back to front in a moment of insanity late one night)

Fuel pump wouldnt prime at all and hand controller would not turn on, I ended up getting it fixed but I cant remember the name of the company that did it, ill post in here if I work it out

Tested the ecu on another r32 and it works fine, so i dunno whats going on with this car????

we generally can repair these units when the polarity has been reversed.

but that seems to not be the issue...hows your battery?

what you mean?

i got another working pfc and put into this car and still didnt work.

i had this issue in my car, turns out it was to do with the 12v constant power to the pfc. i now have the issue of constant 12v to injector 1 which is stopping the pfc from saving settings.

if ya have someone who has test light and multimeter handy get them to check it out, i luckily had my r32 and my mates r32 side by side and we just compared looms and ran tests on each to isolate issue.

We tested the ECU plug against another r32 that the pfc works on and every thing came up the same!!! and still no step forward. The only thing iv found is the battery light does not turn on when the IGN is on and on the working car the battery light comes on???

check the basics on the r32 where the PFC doesnt work

its likely something simple is wrong (with the car, even tho stock ecu works)

the std ECU is a bit stupid vs the PFC and works with hacked setups

in the PFC FAQ (in my sig) look for a section on the ECCS relay

it shows how a mangle car works fine with the stock ecu but doesnt with the PFC

it shows how to correct it as well, from memory something with the ignition is wrong or theres a fuse missing

Had the exact same issue. only just fixed it. Turns out what the majority of people say is not always true. Series 1 and 2 r33's have a couple of different ecu pinouts. I swapped a couple of pins around and its all sweet!

Wow, read things before you post them. I cannot make any sense from this
