Hi all,

I posted up last summer with this same problem but i really didnt get enough info to help me with my problem..

The problem im having is that my GTS is spluttering and stalling like it needs fuel/ At first this was happening only on extremely hot days. around the 40degree mark, id be driving along, start to feel like im running out of fuel and as soon a the revs get lowish the car would die. The problem went away completely all year untill last week when we got the hot spell here in adelaide. This time the problems getting worse though, its cooled down now but i still havethe problem with the stalling and starving for fuel.

I need ideas on what this can be, iv taken it to a number of mechanics and they do not give me any answers, one guy said to me it could be o2 sensor, i sed i think not...obviously doesnt know much about skylines then...

So somethings geting affected by heat, im thinking Crank Angle Sensor, AFM and fuel pump right now.. less likely to be the fuel pump though i think..

Please help with your ideas..Mechanics iv taken it to obviously dont want a bar of it..

Cheers

Don't laugh I have had this happen to another car.

The fuel would evaporate in the fuel rail due to the engine bay being to hot and not actually get in to the engine. Try looking at you engine temp and gauge the engine bay temp. Plus get a service to get you fuel rail checked.

seriouse. Ok ill look in2 that.. Thanks..

i must say though that my gts-t auto gets ALLOT hotter under the engine bay than my GTS, although if you think there might be a problem in my fuel rail then that would explain it..

Iv run plenty of nulon octane boost and flush through it and changed the filter just over a year ago. (Had the original nissan filter on it, lol).

guys the problem is definately getting worse now.

I havnt had time to do a thorough inspection of my lines but so far they look ok. Looks like i might have 2 slightly leaky injectors again, but iv watched them and i cant see fuel coming out just looks bit like fuel been escaping a bit around the injectors.

I have noticed that when i open my fuel tank now theres no sound of pressure being released anymore. I remember there used to be, so does this indicate that there is a pressure leak somewhere in the system? If there is guess thats the cause of my problem..

Cheers

ok incase anyones interested iv found my problem. AFM.. started getting worse and worse untill it went completely into limp home mode..obviously theres dodgy connections in there or something. very wierd because it presented slightly different symtoms than what normally occurs when they go..

Btw, it doesnt show up on ecu diagnostics..dunno why.

You can fix them if it is just the connections...don't throw it out.

      Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...

      Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.

      Well the articals keep saying a Q50s (Skyline in Japan) with a new Manual gearbox. I like the talk about the new looks with the round tail lights. I hope they bring back the retro look like they did with the Z

      Wanna rewrite all of that in, say, 2 or 3 separate sentences, so that we can read it?
