ok so my series 2 has been throwing little tantrums over the last week...

randomly on my way to belmont one night when it was pissing with rain my car decided to start a serious rough idle, slight surging, misfiring and wanting to stall - its an auto. the car would completely drop revvs then instantly shoot back up to over 1k... massive black plumes of smoke coming out the back. went on for about 30 mins then cleared its self up... its continued doing this even after 4 tanks of fuel because im getting maybe 250km outta the tank atm cause of its hissy fits....

checked air leak - found a leak parts on order

spark plugs only 2 months old.

fuel pressure regulator - possible and requiring new one!

coil packs - only done about 100k but still stock so could be?

so i was told take off the cover where the coil packs were cause if they are getting too hot it could be causing these issues... so i attempted myself unaware that bulk shit needs to come off to remove such a simple little thing.... got half way through it yesterday, storm came through so i packed it up to tackle later. last night go to put car back together. achieved. feeling proud as punch.... go to start car FAIL... initially nothing at all but power. fiddled with stuff. car will crank but not fire like there is no fuel BUT i got half a tank FML....

IF ANYONE KNOWS OR CAN HELP ITS GREATLY APPRECIATED!!!

otherwise i might roll it out into the street and burn it lol

Start by looking at what you took off/unpluged and make sure its all back to gether correctly.

Sounds like the coil pack harness is not plugged in correctly. If you car is stock or close to it removing the cover can cause more harm than good by letting crap into that area.

From what you have described it sounds like you Air Flow Meter (AFM) is at fault. Search here and google that will give heaps of things to try and fix it.

easy to tell before pulling it apart, does it prime?

turn the key to on (not start) and see if you can here it or is there pressure in the line (squeeze it near the reg)

Just because an electrical plug looks to be connected doent mean it is. Every plug you touch go back unplug, check if there is anything in it and plug it back in makeing sure it hits home.

Similar thing happened to me with an aftermarket bonnet, water got under the coilpack covers in heavy rain and car dropped down to 5 cyl, then 4 cyl and then it didn't run. Had to pull it all apart and take out the coilpacks and clean it all out and I sold the bonnet which was a shame cause I really liked it. While the car was running on 5 cyl etc I used a hell of a lot of fuel and eventually realised that my o2 sensor had burned out too. I could only travel about 300kms on a tank of gas. Unsure if the two problems were related, but they happened at the same time. Hope that helps.

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
