Hi,

I decided to pull my pod off and clean it a little then thought i should take my AFM and clean that a little too. I unplugged the cable on the side to remove the meter and put it all back together, then my car wouldnt start! It ignites and for a about a second it runs then just dies. My sensor sw/check on the power fc says the AFM has no voltage, sometimes it increases by .01 v but nothing more.

So I pulled it apart checked it all and put it back together, no difference.

Again, put the plug upside down and no difference.

I really hope i haven't fried my AFM!

Woops double post sorry!

Seeing as the signal loss from the AFM occurred when you ... removed the plug, I'd assume the loom is damaged around the plug area. Search for pin designations, and test for good ground, power etc.

Get someone to wiggle the plug while you check the hand controller, go from there.

What did you clean the AFM hot wire with?

EDIT: F5 before clicking submit, when will i learn.

I didn't actually clean the entire AFM, I brushed the intake side off. The plug is a weird looking one, it sorta sits and you screw it in and there are 3 pins the come from the cable to the AFM.

Ok played around with a friend and determined that the ecu is still receiving voltage from touching it with fingers (human electricity????).

Fiddled some more and fitted the plug in the AFM and received some voltage! Only .25 volts though and this wasn't enough to get the engine running.

I reckon the pins on the plug have bent or the AFM receiver isn't conducting well.

      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

      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.
