For some reason my '05 350z will get stuck in first gear when parked on a hill, this is only if the gearbox is holding it (if the handbrake is, its fine). 

I won't be able to pull it out of first gear, even if I push the clutch in with the car off and it won't roll back either even with the clutch in.

The only way to release it, is to turn the car on with the clutch in and then I can pull it out but it always makes a big thud. 

Is that normal, in my R33 I can push the clutch in even with the car off and load on the transmission and change it out of 1st.

I don't see that as a reasonable excuse for not engaging the handbrake, at all.

I hope you're at least turning your wheels in the right direction for your vehicle to veer into the kerb so that it doesn't roll off and damage someone else's vehicle or kill someone.

Pardon my judgmental attitude but part of motoring is thinking responsibly about everyone around you and your heavy steel weapon. We have parking brakes for a reason. They are the primary safety device, not your gearbox.

Let me say I almost never use the park brake on my autos, but that is a very different situation to manual. 

Auto has a pawl which locks the gearbox. Manual is just using engine compression to hold the car which is not safe depending on the slope or unexpected extra load like another car or a person leaning on it ;)

I think best practice is pull up to a stop with foot on the brake, pull up the hand brake, release foot off the brake pedal, turn off the car, clutch in (or not, don't think it matters once car is off) put the gearbox in 1st or reverse depending on whether you're facing up/down.

 

I do this in autos too, foot brake, hand brake, release foot brake, put lever into P.

I'm not so trusting of that idea either. I know of two people with two vehicles whose pawl did not hold their vehicle at all and made quite the amusing ticking sound as they rolled away from them. One caught his vehicle in time. The other, well, the write-off was a blessing in disguise anyway. To me, they're always a backup to the parking brake, not a primary.

Many cars do have neutral inhibit on manuals.  The Holden Cruze has such a crap handbrake they will roll away unless you crank it on hard and the owners manual specifies to leave in gear. Mate had one roll out his driveway across the road into neighbor's yard. Everyone was ok luckily , and from my perspective it was very funny.

It always is when it's not your car. :P

Which reminds me, I need to readjust the parking brake on my V36. Nobody has really been capable of giving it a proper adjustment, working on the cable instead of the shoes themselves. I always get a little nervous creep from it.

Squeezing the oil out of your engine bearings to hold the car on a hill sounds like a shit idea to me.

Hey @Ben C34 was this directed at my method?  Just would like to know how you mean as I am a mechanical numpty.

 

Cheers,

Not you directly mate. What you have described doesnt load up the gearbox and then engine unless the hand brake doesnt hold.

I never leave a manual parked in gear. Accidental key turning can result in panel damage because there is no neutral inhibit on a manual.

The handbrake is there for a reason.

Everyone here veered straight off what I was trying to ask, I wasn't after a safety lecture. I don't usually leave the car in 1st gear on a hill ffs. 

What I was trying to ask is, if I am on a hill and for whatever reason the gearbox is the reason its being held on the hill (lets say its in a controlled environment, in the middle of mexico, with bubble wrap all around it and cotton wool just in case) it won't let me pull it out of gear (even with the clutch pushed in of course) unless I start the car. 

That is on my V35 with a twin plate, solid center clutch. It's been in the car for over 20,000km and doesn't show any other signs of dragging the clutch. 

My R33, you can hold it on the hill in gear with the gearbox and if you push the clutch in even with the motor off it will let you pull it out of gear, the v35 doesn't do that. 

 

Is that a symptom of a twin plate clutch, or is there potentially something else wrong - like maybe clutch drag even though I highly doubt that being the issue.

      R33 Fuel Pump & Brakes after alarm swap

      By GTSBoy · Posted

      Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.

      @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html

      These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.

      The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.

      It's amazing how well the works on the leather seats. Looks mint. Looking forward to see how you go with the wheels. They do suit the car! Gutter rash is easy to fix, but I'm curious about getting the colour done.
