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

    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
    • So, a bit of a side trip, but one that might be interesting for people with JDM cars and japanese head units. I know @Pac previously posted about a carplay/android auto adapter he installed which used the AUX input, and @V35_Paul put in one of the Tesla style units that replace both screens. The option I went with was a Lsait LLT-YF-VER5.87_2 (https://www.alibaba.com/product-detail/Lsailt-8GB-Android-Multimedia-Interface-for_1601187633672.html). Price was $1,150 for a single unit although they are much cheaper if you are willing to buy 2....$857ea. Make you you get the version 2 not version 1, it is faster and has a better UI - this is the manufacturer listing: http://www.lsailt.com/product/348.html. BTW if you've never bought from Alibaba before, don't be concerned....these guys can't stay in business unless they are responsive, ship fast etc, they were excellent (probably faster shipping than most local places) So, this was my task for a lazy Sat afternoon....looks complex but was all done in a few hours (it probably helps that I had some of it apart before so it was a bit familiar). I also decided to add a HD USB drive recorded at the same time and the unit also supports an aftermarket reverse cam (if you don't want to retain factory) and also AV in and HDMI out It looks much worse than it is, in fact in was genuinely all plug and play (no custom wiring at all). This video was pretty good (skipped a few steps), unfortunately they are an Aussie seller but no longer sell this unit (I guess Carplay/AA adapters are easier to install and much cheaper) https://www.youtube.com/watch?v=T5hJfYOB8Dg
