hi, everyone,

 

there is another question for all of you again; :tongue:

 

I haven't drive my z for about a week, and now I can't even start the engine, I tried to start it up by connecting the battery to another car's battery, but it seems useless, and nothing I could do with it, any idea?

 

Thanks for all of you

 

any advise appreciated

Check the -ve cable from the battery to where it is bolted onto the body. Does that get warm when you try to start it and also do the lights dim when you try to start it ?

 

When you tried to start it did you connect both the jump leads to the battery, or just the +ve and then the -ve to the bodywork ?

AndyP:

 

Thanks for your replied, do you think it is necessary to contact Nissan in my local area to sort it out? As I have really tried all what you guys mentioned here, and even the mechanic of AA tried to fix it as well, but it seems not very helpful. therefore, I haven't got a clue about it.

Dickens,

 

Unless you know the Nissan mechanic knows what he's doing on 300's, I would stay away. You may well end up with a huge bill..........................

 

Do you own a video camera?

 

Vijay

yes, I know, I may end up with a huge bill, but there is no one to help me in my local area. That's why I think the Nissan is the only places I can go.

 

Yes I have a video camcorder.

I personally wouldn't go near any Nissan garages near me.

 

OK, get someone to tape your car while you try to start it with jump leads so everyone can see/hear exactly what your car is doing. Then ask nicely on here if someone can host it for you.

 

As AndyP said, connect the + to the battery terminal and the negative to some part of the bodywork (I always connect it to somewhere on/around the plenum when I've had to jump start).

 

And if we manage to get your car started, £20 for subscription ;)

 

Vijay

it's no problem to subscript, mate I am going to subscipt after I have repaired it, as still dunno how much I expect to pay for repairing, so............. :cry: , anyway, I took my zed back home, as the repairer don't even know what the problem is after a week, it's terrible, isn't it? Therefore i am still looking for somewhere to started it up for me, I am really no idea, any suggestion?

 

I know this quesion has been asked by me for a several time, but it's true that no one can tell me what I gonna do.

 

your suggestion may save my zed, so please drop me a line if you know something about it

do what I said about videoing it.

 

Vijay

Hi everyone,

the problem I had is sorted by replacing the Spark Plug, because my old one are fludid already, and the repairer told me it is really difficult to turn it over if the spark plug fludid like my old one. Now the repairer replaced a set of NGK, and it cost me about 20 quid (instead of my old one - HKS, i bought it for about 120 quid two months ago), after turnning it over, and everything is fine, BUT when I accelerate it and the turbo is coming when the rev about 4000, then there is a big 'bob' sound from the back of zed, then I can't accelerate it anymore for about two second, after that, everything is back to normal, it is NOT always happend, I would say sometimes happend, therefore I don't know what's going on again, there is another question for all you guys :mac1: , anyway please give me some advise, as I have been told it may have some big serious problem

WTF ???, this is bullshite :confused: no offense Dickens but please don't ever go back to that 'repairer' again.

 

Turning the engine over has nothing to do with the spark plug, fireing/starting the engine does. Is this guy a mechanic or just some dude you know ?

 

If the car won't start the first thing you do is check to see if the engine is turning, if yes, is it turning quick enough, no - then it's a problem with the battery or the starter. Yes, then is it firing ?. No then it's a problem with the spark/fuel or compression.

 

The first thing you would do would be to check the plugs to make sure they are in good condition. then onto fuel , then check compression.

 

Are you saying it took this guys almost 2 weeks to even check the plugs ?

 

Also, please don't tell me you left the HKS plugs with him ?. If so get them back mate, if the engine was flooded then the plugs wouldn't have been able to ignite the fuel correctly, but this doesn;t mean there is a problem with your plugs. Also may be worth finding our what plugs he has put in, get the part number so we can let you know if they are ok to use.

 

The problem with the engine power dying at 4krpm will be one of two things, your TPS or the fact that the intake has sucked in some water vapour. Do you have an induction kit or just your standard air box ?.

no, the hks plug is in my hand now, the NGK one is brand new, and yes the engine was turnning but not firing, that's what the problem was. I haven't got the aftermarket intake, the only intake I have is standard air box. Do I need to get a aftermarket intake to sort it out? Sorry about my knowlegement of vehicle, as I don't even know what TPS is.

 

the repairer/mechanic started the engine up for me although he has taken me about 2 weeks, that's what I want to fix, and he did, so I think that's enough for me. Anyway I really what to know what the problem with engine power dying when I drive it hard, please tell me more about it.

 

Also I have been told that becaue the spark plug (NGK one) is a normal one (for normal car - Rover), not for a performance sport car, so it may harm the engine and that's why I have the problem with the engine dying (not only at 4000rpm, as long as you drive it hard and when the turbo is coming, also it is NOT always happend), does anyone know something about it? any advise appreciated.

"and yes the engine was turnning but not firing, that's what the problem was."

 

lmao your having an early april fools joke arn't you??

cos in your first posts in this thread the car wasn't turning over

if you had told us it was, you could have saved yourself a bundle of cash and had the car running a week ago lol

yes, I know, becuase I am not good at vehicle, so I thought the car was not turnning over, but when the mechanic inspected it two days ago, he told me it is not firing, that's why he replaced the spark plug for me. I know if I tell you early, it may saves a lot of money and times to get the car running, but please understand that my english is not very good especially listenning, I may misunderstand what all of you means. Anyway Thanks for that.

Hi Dickens,

 

Ok to get rid of the problem, do the following.

Clean the sensors on 1) the TPS, 2) the AFM, 3)the temp sensor.

 

Your problem will then go away (hopefullly).

Don't come back until you've done all three :D :D (joke)

SMW1:

 

please let me ask you one more question before I clean the sensors you have mentioned..... Can you please tell me what is TPS and AFM stand for? and briefly tell me where can I find it? I know it is a stubid question, but I really dunno what the hell it is.

 

PS. you won't see my post after you replies until I have clean these three sensors, lol

 

Big Thanks

The TPS is the throttle position sensor which is a little black box on the right hand side of the plenum (from the front of the car), where one of the fat black pipe connects. Take of the plug and give it a clean up and a spray of WD40. The AFM is the Air Flow Meter which you will find under the nose panel on the front of the car, do the same for that. The Temp sensor is found on the metal water pipe on the front of the engine, there's 2 there, a small one and a slightly bigger one, the bigger one is the Temp sensor. Not sure if he should be sticking Rover spark plugs in it unless their the same which i doubt!? Sounds like hes found one that fits the hole and stuck em in! Clean up your old ones and put them back in.

Yep, would agree with the above.

I'minterested to know what plugs he has put in. Can you find ou the NGK code for us ?

 

But try cleaning the sensors first ;)

"The AFM is the Air Flow Meter which you will find under the nose panel on the front of the car"

 

I have done the other two, but I am not sure where is the AFM, as I don't know where is the nose panel actually. Sorry about it, would you like to explain it a little more for me, please?

 

Also, I have clean the HKS plug already, and it looks ok to work I think, but I haven't got a tool to take the NGK one out of my engine, so I'll let you know what NGK code number it is in a few days.

 

I don't know the problem is still here or not, as I haven't tried to test it yet, I will try it to see whether it works after I find out where is AFM.

 

Thanks for your help

This may help :-

The air filter is attached to the AFM.

I have been told that the problem I have now is dangerous to drive, as it may has some serious problem - the engine or turbo is nearly finished, that's what my friend told me, do you guys think that is this really made sense?

also I have clean the AFM and tested it already, but it seems not very helpful the problem is still here, any ideas?

Dangerous I think not, pain in the arse I think so.

 

So have you done the following....

1) clean temp sensor connector ?

2) clean AFM connector ?

3) clean TPS connector ?

4) clean and put HKS plugs back in ?

 

I bet you haven't ;)

no, the only thing I haven't done yet is HKG plug, as I mentioned before, I haven't got a tool to take the NGK out of the engine, and put the hks plugs back in as well. But the other three I have done already, I am pretty sure about it, as I followed the link by AndyP to make sure which connector I need to clean, so........ let's see what happen if I replaced my HKS spark plug.

 

Is that mean you don't think it is dangerous to drive hard? as I am worried about it becuase of the word from my friend.

I agree SMW, by the sound of this -

 

"after turnning it over, and everything is fine, BUT when I accelerate it and the turbo is coming when the rev about 4000, then there is a big 'bob' sound from the back of zed, then I can't accelerate it anymore for about two second, after that, everything is back to normal"

 

Sounds like your talking about a backfire down the exhaust, if you've done all the above maybe try a fuel filter change and some fuel treatment stuff.

have you got any good recommendation for fuel treatment stuff?

 

Thanks

Thanks

 

Go into Halfords and pick up one called 'Power Pack' I think.... Its got 2 bottles in, fuel system cleaner and octane booster.
