Hi all,

ive been having some on going issues with my AFM's on my R32 GTR for a little while now (havent had the money to fix). i pulled the top one off just to have a look if there was anything obvious. there wasnt, so i gave it a clean and threw it back on the car. now when i go to start the car it wont fire. all that hapens is it cranks but wont fire up.

so im just wondering if the AFM would actually cause it to not start like this, or could there be another problem? as far as i can see, i havent left anything off when i put it back together.

any help on the matter would be greatly appreciated.

cheers,

matty.

- Run a diagonostic code from your ECU.

- If you suspesct its the AFM, open it up and check for dry solder joint (there is a guide in the DIY section)

- Check sparkies, Coil Packs

- Check fuel pump

cool.

i just put a set of splitfires in last week, and plugs a couple of weeks prior to that, so i hope its not them...

i think the fuel pump is ok. it fires up when ignition is on, then when im cranking, i can smell it from the engine bay...

im going to have a look at the DIY section.

just out of interest, there isnt an earth wire that attaches to the AFM that i might have mist is there?

well ive replaced the afm's, but to no avail. she is still dead to the world. i really dont know where to go from here. ive checked for spark, fuel, and ive checked every single fuse in the car. i even disconnected the battery for 10 minutes to see if it would reset the computer, but no dice there either.

im running a power fc (no hand controller), is there some way of doing a code check to see if there is a fault with the system?

other than that, i am at a loss...

PLEASE HELP ME!!!! :wacko:

cheers, matty.

Hi Matty, the first and easiest thing to try would be the ECU itself. If you still have the standard item install it and see if you have any luck. Failing this, and without a diagnostics machine it's simply a game of elimination. A few other common items that will cause this are:

  • Cam Angle Sensor (CAS)
  • Ignition Module

PFCs don't have a "reset" mode, like the factory ECU does.

How old is the battery? Do you have enough "juice" to get it started (try jumping from another (running) car). (I had the problem of not wanting to fire, even with a battery pack. Needed a jump.)

unfortunatley i dont have the factory ecu. ive checked the ignition module and its fine. is there a way to test the cam angle sensor?maybe with a multi meter or something?

the battery itself should be fine, i put it on charge overnight but it made no difference.

im really stuck on this one... :D

    • @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
    • I started removing the tank a while back with the intent to give it a proper clean. Got to a bolt that I couldn't undo completely due to a diff being in the way, so just said f**k it and siphoned the gluggy old fuel out and called it a day. Looking it the tank it looks less corroded than the one in the pics for that billet hanger from Frenchy's anyway. Isn't it the fuel filters job to worry about this stuff? I scraped off most the crusty shit of the hanger but will give it another go before reinstall coz maybe the fuel and return pipes are also full of gunk  
    • Pretty sure it is a common fault. I believe this is the only part you need, but don't quote me as I don't have a V36.  I also believe it is a bit of a pain to change and the device needs to be encoded to the car once it is replaced, so may need someone with the right tools.

    • Pads for R32 GTS-t, R32 GT-R non V-Spec (Sumitomo), R33 GTS-t and R34 GT-t are all interchangeable. R34 GT uses a 2x piston caliper, hence it didn't fit.
    • Checked with amayama and nope, the full S2 manual set is not available anymore. Unsurprising, but still disappointing as the ? on availability gave a glimmer of hope.
