Just had car fully checked and everything seems fine from spark to fuel.

Until I checked to see my power fc inside and looked like this.

Car is still hunting bad on idle and wont drive past 2500/3000rpm and runs pretty horrible with no power.

Most likely this is the cause as have changed just about everything.

Would anyone let me borrow for 5 minutes there power fc to test so I no for sure it is the problem, but I guess it still needs replacing by the looks of it lol

What do you guys think.

Holy Shit, I'm suprised it's driveable at all

Yes I'd say that is your problem. Do you recall anything that may have done this (bridging plugs etc)? Probably just the Power FC crying enough over age but if it could be something that has caused it on your car, then you need to fix that before replacing the ECU or it will happen again

I bought it few years ago and it had water in it and didn't no much then and as when I hooked it up it made a choooof sound and smoke came out and didn't make much of it back then so really forgot about it.

It ran ok till now but I just bought a adaptronic ecu all hooked up with a tune in it similar to my set up and still done it and I found the problem injector 5.

As soon as I disconnect it does nothing in engine sound at this point as all other injectors are fine as they change the engine sound when I disconnect the plugs from them,but sometimes it might start working but for now that's it.

Must be cause I ran the injectors real hard on e85 pushing 330rkw and think there 550cc.

Either blocked or leaking injector 5 but there's really nothing more but that as I changed every thing and this problem got worse after e85.

Still needed to change the ecu no matter Wat the outcome was as that PFC was ftt up and guy ripped me off which was not nice for $900

      Hello, sorry for being late to join the discussion, but my clock just died on me.   Ive tried to look at Michaels digital clock repair.docx and it doesnt work maybe the file has expired.   Please let me know if you can re upload it or take some youtube videos to show us how to get the clock installed? thanks

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
