OK this is a weird one, but here goes.

 

I was ordering my food this evening and just as i asked for me chicken nuggets the car jumps to 1500rpm and just rises up slowly to about 1700, which is strange i thought having not touched the accelerator, anyhoo.

 

I whack it in drive and move on to the next window where the same thing happens, still intrigued i move to the car park and wait for the food.

 

........

5 mins later got the food go to start her up and not much happens. She turns over, but wont start and after a few seconds there is a REAL strong smell of fuel, not knowing what to do i sit there and eat my food whilst praying to the maker (not NISSAN!!) that she'll start when i try in a minute cause there is the usual crowd of novas etc staring at us and i dont need them laughing at me and my tempremental car.

 

So i've finished me dinner and start her up. With a little bit of coaxing she does start but runs rough for a second or 2 and then fine until i hit the accelerator (gently) where she proceeds to fake a stall and then surge into life. After about 5 mins everything is back to normal.

I even started her up a few mins before typing this and it was all ok so anyone got any ideas??? Does my car object to Mcdonalds (this being the first visit i've had in her) :D

 

Weird

I think that a Big Mac would have sorted her out :D :D :D

 

(couldn't resist that one ;) )

A clean of the throttle bodies could be in order, that and giving the injector connectors a good press on, may cure it, only takes 5 mins so gotta be worth a shot.

 

Might be worth disconnecting the battery for a couple of hours to reset the ecu, as it may of got its knickers in a knot for some reason.

 

Good luck with it.

one word "PTU"

 

Clean the ptu connectors and make sure the connector is on tight !

 

Olly.

Run an ECU diagnostic and see if there is an error code stored in there.

tps connector wires - give em a waggle

Hi Pete,

 

Hmmm, Chicken McNuggets will do that to the best of us ... but in all seriousness, the advice offered above (PTU connector, Throttle bodies and while you're in the cleaning mood take some time to clean the temp sensor - big yellow connector on top rad hose) is good and you should start there but one thing that sticks out is that neither of those would produce a strong smell of petrol. Have a look at all the clips on the petrol hoses in the engine bay and tighten them up. Next I would look at the fuel filter (may have been temporarily clogged) and then at the fuel pressure regulator and fuel pressure dampner - perhaps change those for new ones. Fuel pump would be another one to look at if the above doesn't help. If none of this helps get back to us and I'm sure someone can perhaps shed more light on the matter.

The ptu would as you get no spark when the engine is being cranked !

Thanks for the suggestions, i will have a look over the weekend and see what i can find.

 

Another question! Do you know how i can date my car? I've found a website with a list of chassis numbers but mine doesnt fit in for the year that it says on the logbook???

 

Cheers

 

Pete

pete. my car was doing exactly as you describe. i have literally just come in from fixing it. the top wiring connector to the top of the ptu was all green and corroded, a little scrape with small screwdriver, a squirt of wd40 and fixed. where is the website to check chassis numbers against year of car?

 

cheers

...lee

Cheers for that lee. Its a bit dark now so i'll give it a go 2moro

 

Got the info about chassis # from the OZ club, but it's only for J-Spec Z's

After removing the cover to the ECU I see that i have a different one to the one in the pics from the ttzd website. It's considerably bigger and is on the right hand side instead of the left. Does this mean i have an 8-bit board?? I didnt get round to do the diag as i couldnt find a small enuf screwdriver, but will do it 2moro, cause now its time to get p1ssed!!

Pete, drive your car and date a girl you sad git!

 

:D :D :D

Pete, drive your car and date a girl you sad git!

 

HAHA...Well i is desperate :D

 

I gave all u guys suggestions a go and came up with this lot:

 

PTU

 

The connectors were fairly corroded so took some emery board to them.

 

ECU Diag

 

Got a 13 so i checked the temp sensor connector and that 2 was in need of cleaning! Ran the diag after that and it came up with 55.

 

TPS

 

Again this was corroded abit so was cleaned.

 

TB's

 

I didnt fancy getting my hands too dirty so didnt bother with these :eek:

If i do get the same problem these will be the first on the list.

 

Thanks for all your suggestions. In answer to my own question about dating....:D I have since got my logbook from the dealer and it came with a BIMTA certificate stating date of registration in Japan as November '89!!!!

 

 

Cheers
