why does it matter? i don't care if you think it's weird or not funny. i've got a quirky sense of humor that you'll never understand through text on a forum and i'm not planning to change it unless i see something better which you probably won't approve of either. wasn't supposed to be a come back before because it's not an argument. just me being me.

Hey guys probley gona get flamed like hell but, ive taken off the standard cross over pipe off my NA skyline and replaced it with straight steel piping without a resonator box. Atm, from the throttle body there is a 45 degree 3inch silicon joiner, then about 30cm of metal pipe then a 3inch joiner, the AFM and a pod filter. As soon as i start the car it stalls instantly, if i rev it slightly it will run but very poorly and as soon as i take my foot off the accelerator the car stalls.

There are two hoses that are not connected to anything atm, on runs to the intake manifold and the other to the top of the cam covers, these at present are not joined to anything. how can this problem be fixed?

(Worst case senario, ill just put the standard cross over pipe back on. But would like to get this to work as have heard the induction noise using metal pipe sounds ok :P)

Thanks Nikk

Thanks to Zebra this may of been resolved, apparently the pipe running from the manifold back to the inlet pipe needs to be plumbed into the intake pipe itself..

Yep. Sounds like a severe vacuum leak. Basically by not having that hose connected you're allowing a lot of air into the intake that is un-metred. All air entering the intake has to go through the airflow meter otherwise it will run like shit and run lean.

I know i'm and apprentice mechanic and I should know what's wrong with the car but I don't and just want peoples opinions in what might be the problem.

Recently at times my fuel pump wont prime on start up but after you hit it then it would prime but today it has been realy bad, went to start it to go to work and didn't prime and it needed a few good hits and when leaving work today it took a couple more hard hits to work then filled the car up on south rd with BP Ultimate as usual and was about to exit the petty station and it stalled and wouldn't start for about 10min even with hitting the crap out of the fuel pump and swithing the ignition on and off to get it to prime.

Finaly got it started and 1km down the road it stalled again and did the same thing it did at the petty station........wouldn't prime for 10min, once it started I took off and when leaving some lights 2 min after it surged after changing to second (full tank of fuel)

Later after I left a mayes house it stalled after going around a round about a little too fast by accident after the rear slid out abit but the car started shortly after while cranking the car and having a mate belt the crap out of the fuel pump.

My 32 has a Walbro but not sure what one exactly as it came with the car. I wriggled the wires on top of the sender unit to see if that would do anything but it didn't. I have been told before that fuel pumps don't start to die they just die without warning that's why I would like some opinions.

Cheers Tim

If the brushes on the fuel pump motor are worn to there limits then they wont be contacting the armature on the shaft to energize the magnetic fields to make it turn.

A wire could break but still make a circuit when the insulation is holding it together. Then when everything warms up the insulation stretches and pulls the wire apart

Try puling each wire from its ends and see if the insulation stretches anywhere.

Check for voltage at the pump you might see the volts go from 12 to 0 then its the wiring. If you have constant 12v at the pump and the pump stops then its the pump.

Also do the relay mod and run a heavier wire to the pump through the relay.

I think you solved your own issue just buy a hammer to fix it..lol

brads right most likely R31 do that all the time,

also

check for dead fuel pump relay, think its a green one on that car. or some nissan use a transistor inside the ecu , which fry with big loads on big pumps

bad ground on pump ?

vapour locked, bad fuel.. when it happens open fuel lid let out hiss, try to start the car with the lid off fuel tank. E85 and E10 do this a lot , even more so at high altitude , not so much here

low voltage/intermittent voltage from worn out ignition barrel , heavy key chains are death to cars, car has a tiny fuel leak that airlocks the pump

Hey people, What does it mean when your car pretty much stalls taking off from traffic lights, coughs and splutters until you rev it a little, and power cuts out as your driving? Does it in every gear, but doesn't do it every/all the time (exept for last night) Had the 'exhaust gas temperature' light flash a few times last night as well, guessing that'd be due to higher revs, as last night was the first time the car has done that. Has stalled a few times when starting it up, only in the morning when the cars cold though.. Never cuts out completely when driving, just seems as though the motors not getting fuel? Seems to run a little better when I put octane booster in. Had a new turbo and stock exhaust put on recently, dont know if that'd have anything to do with it though? Got me baffled.

    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
