Ok so now my car is turning over and all primed, but its not starting. Im thinking that maby the AFM is wireed incorrectly as i had to hardwire the q45 when I had it on theere with the old utrbo setup and now that im going back to stock the rb25 one has to be hardwired too, so im thinking that maby I have the plugs mixed up.

Any other ideas on why this hunk o crappo isnt starting, I REALLY need it to be going, im talking life or death (ok well maby more like big chunk of cash or kick the crap outta my car)

Cheers

OK compared it to a ,ates rb25 afm layout and its the same.

I slid the cas plug on and of and it fires a tiny bit and then just keeps turning over. Could my cas be on its way out?

I was also thinking maby my AFM is dead.

I know my coils are old but there is no reason they hsouldnt be firing.

I checked all connections and everything so if anybody could help me it would be much appreciated, c

heers

I know you said you checked a mates, but the wiring is different on series 1 and 2 R33's - see below

Not sure what you've done but you cannot just do a straight swap. You need to modify the VQ table in the ECU to get the AFM working correctly (on the same scale)

Skyline (RB20, 25) R32 & R33 Series 1 & 300ZX (Z32) (Same, wire F not used) - 80mm

Wire A - Not Connected

Wire B - Signal

Wire C - 12v Ground

Wire D - Signal Ground

Wire E - 12v Power

Skyline (RB25) R33 Series 2 - 80mm

White with Blue Trace - Ground

Orange with Black Trace- Signal

Black with White Trace - 12v Power

Inifinity (Q45) - 90mm

Wire 1 (White) - Signal

Wire 2 (Black) - Ground

Wire 3 (White(or Red) & Black) - 12v Power

I was running a power fc with the q45 and I am now running the stock afm with the stock management. The q45 had to be hardwired as I ddint have the plug for the q45, and I dont have the stock plug so it needs to be hardwired again

What I actually needed was the sequence of the wiring e.g

Pod

pin1 = red

pin2 = bluw white

pin3 = orange/white

Turbo mouth

If you catch my drift

      Price seems pretty good to me. Also seems a hell of a lot cheaper then buying another vehicle that only ever gets used for towing.  I'm a long way from you mate, I'm a couple of hours out of Brizzy.

      The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.

      Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?
