hi guys how yous going, went for a drive to the city lasat night and yes it ws pissing rain and i got the carbon fibre bonnet with the vents in it, as we were coming back to the area my car just stalled and we tried starting it several tyimes and it wouldnt kick over, i just got the car tuned down at racepace last week with a sard 280 pump whih i bought of a forum member on sau and it was second hand also, also the nismo 555cc injectors and a niusmo fpr, now what i think the problem is it could be the fuel pump, it starts like 10mins later but then it drives for about 2mins and then switches off, its really weird, the previous owner of the sard 280 said it hasnt even done 200km on the pump, well all the blokes that were with us said it could be the fuel pump because i dont think it has anything to do with the injectors as ben from racepace would of told me, the car is a at a mates house as we had to push it for like 2kms in the pooring rain but just want to knwo what it could be so any help or advice to check anything will be good guys and what i also thought it could be was i have a vent right where my z32 afms are and a little bit of water got to them but i didnt see that could be the problem as the car should just konk out like that if it had anything to do with the afms the car would just be idling funny i would think but yer this is the first time it happened and it was also in the rain, car never comes out in the rain but had to drop someone off and just went out from there instead of going back

the car just wants to start but just isnt kicking over, i wonder what it could be, can it be injectors or will it be the fuel pump?

thanks heaps guys

cheers tony

Hey bro.

dont think itl be the injectors. Could be the AFM is all clogged up. Have you tried cleaning it with some brake/electrical cleaner?

Another thing, can you HEAR the fuel pump prime when you turn the ignition? When it does start up, can you drive it/rev cleanly? No misfire?

disconnect the CAS then remove fuel hose from inlet to your FPR and see if there is fuel being pumped out. My guess is your FPR has come loose and wound itself out and cut off fuel.

Also your car will run without AFM run like crap but it will run so i dont think it could be those for your starting problem, would be for higher in rev range but not starting.

Is it just me, or are you guys missing the REAL basics?

You have a vented bonnet, it was pissing down rain.

You've filled something electrical in the engine bay, most likely your coil packs, with water and they've stopped working.

You're going to have to disconnect everything electrical and spray CO contact cleaner in there, then put it all back together.

Bitch of a job, but it's the only way, unless you wait about 10 days for the water to evaporate.

I'd be mainly looking around the coil packs.

Pull the coil pack cover off, and see if any water is sitting down under there.

It may have been in the rain before, but depending on how hard it's raining, the motor may have been hot enough, with not enough water coming in previously to cause issues, as it'd just boil the water off.

The other night, may have just been way too much water, and it's flooded the top of the motor.

But I'd be mainly looking at the coil packs, and their connections.

Hey mate, i had the same problem with my SARD pump, u need to make a better earth terminal for it, there is a white wire the goes into the pump, its the earth for the incab noise reduction feature thing. tap in another earth line and it wont affect it again,,

Just needs to be earthed correctly,

its very easy mate, you dont need your mechnic to do it. its one simple wire to hook up..

In your boot where the wires for the fuel pump are located..

There are two plugs that hook up to your pump and computer n other things, like the incomfort feature for the standard pump, basicly restricting voltage so its not constantly running,

Anyway take the lid off, four screws.

Then take the plug off to the left hand side,

Then there is two wires, on that plug, yellow and a black with a lil bit of yellow on it..

tap a line into the YELLOW ONE, (new wire) then make it long enough to earth it out, tape it up and your good to go..

It will never fail again. and it will start and run every time. I think it must just be a common fault with 32GTRs the sard pumps, becuase a mate of mine also had the same issue,

try it mate and tell me how you went..

wont be the coilpacks.

my cars got a vented bonnet and was out in the rain for a while, water got into the coil packs, car still started etc, but ran like a dog. 2 coils weremt firing cause they were swimming in water.

So his can't be an issue because maybe 6 coils are now swimming in water?

Do people around here not have common sense?

What you've just said is:

I had my car in the same condition, and it can't be what you've said, because I had happen what you said, just not quite so severe...

Smart...

Simple test, switch the ignition on, do you hear the fuel pump prime? Yes? Unlikely to be a problem with the pump.

No? If the battery's ok then you might want to have a look at the fuel pump, is power getting to it?

You can try directly wiring positive/negative from the battery to the fuel cell thing (the part the wires in the boot plug into which go to the pump, be careful) will let you test if its working.

However, I do agree that its a good chance you may have water on your coil packs...(note fuel pump will also stall the car, but there's more than one cause).

Foney, in regard to the fuel pump not been grounded, I had the same issue, car just wouldn't start one day and fuel pump had to be re-ground, not sure if its a stock fuel pump or not but it was ok for about a year (R33 GTR) and it just died a week ago...(fixed now).

      R32 GTS (RB20DE) Injectors Replacement

      By MBS206 · Posted

      If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.
