Hi All,

I fried my powerfc and looks like I may have done some damage to my car as well. The car doesn't start on the stock ecu. Diag reports no errors found. All lights appear to come and the usual stuff happens just doesnt start. Fuel pump does its thing. Checked all fuses, they're all ok. Checked for obvious wire damange, nothing visible. The PowerFC is cooked and has a burnt track on the board, my biggest concern is getting the car to start, ecu is replaceable just hope theres no perm car damage.

Need a good auto elec to come to my place (tullamarine) to sort out why it doesn't start. Car is under the carport but can be pushed onto the drive way or what not.

If you know anyone who is a good auto elec (or even just a car fixer-upper-er) please let me know as soon as possible. Will pay cash / beer / anything else just as long as they can sort it out.

Thanks

trying to be a clever dick trying to see if the airtemp sensor would come up. must have tapped the wrong wire and it fried the ecu, burnt smell and 1 track is burnt on the board. worst part is car doesnt work, can buy another powerfc if need be but just hope car is ok.

so when you crank the key over... do you get any noise at all?

\eg feul pump turning on, or engine trying to crank or starter motor trying?

you sure you checked all fuses near the battery, under the steering collumn and in the engine bay in full day light?

thanks for replies, i checked all fuses next to steering column and in engine bay, all appear OK. when i try and crank it sounds normal, i can hear fuel pump and it does its usual crap just doesnt start. almost sounds like the immobiliser is stuck on, but the security light goes off so i can only assume its working ok, stock 33 s2 alarm.

thanks ash will speak to andrew hopefully he can work some magic. my guess was ignition coils / spark sequence

danny disappeared a few months ago so i wont bother him, and i know andrew a bit, well ive met him and spoken to him so it kinda makes it a bit easier.

I know a good auto elec in Sunshine, but you mentioned you wanted someone mobile.

If you want i could come over and we could both go over the car. I am not an auto elec, but i am free and willing to help. You may have missed something obvious, easy to do when stressed :).

Anyway, give me a call if you like. 0427 076490

checked a stack of fuses, even found some more in the boot. all ok. listend for injector tap when cranking, all ok. did complete ecu reset and wiring check all ok. checked all the fuse wiring. all ok. still doesnt start. the burnt track on the powerfc board is #45 which is "ignition start" on the ecr33 diagram so bozz is going to get back to me about it.

thanks for all the help guys, really apprieciate it. one of the best things about the skyline community is good help readily avaiable (and on a sunday too)

ok did some more testing and tryring stuff. injectors tap so they are working. fuel is working, i found out its wire #44 which is actually the gearbox neutral switch selector. so our initial thoughts were maybe that switch is busted. fired up consult (the proper good one) and in neutral switch reports on, move into gear and it reports off so that sensor is working OK.

checked the other sensors in the good consult i had and found that water temp is -23. this was the sensor i was using as my donor so it appers i cooked that. the first consult i tried was a different version and it said all was ok but didnt print sensor values.

this other one i tried shows the values and water is -23 so thats a good sign its borked. will get another sensor tomorrow and try and swap that and see if she cranks over

more tomorrow

next question anyone have a spare donor rb25 water temp sensor? if not ill have to check out repco for a new one, just would hate to buy one and it doesnt fix shit, oh well my own fault i guess. hopefully its an el cheapo generic item and not rb25 specific.

a quick search of the for sale section and i found one, pm sent, he replied, i said can i come n get it, he said sure, went and got it and im back home now with the new sensor ready to go. dedicated club memebers i tells ya, awesome community

    • Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.
    • Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that
    • I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.
    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi
