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.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.

      ECU sees many times the speed than speedo does (R34 swap)

      It's needed for rolling idle up, and I think it is a decider on VCT also.

      I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
