So right now my car is in pieces, i have my head out of the engine bay and practically every sensor in the engine bay is disconnected

Today i was trying to drain my gas tank so i thought i'd let the fuel pump do the work by priming it and let the fuel feed line go into a canister

so as i turned my iginition to ON, nothing happened... so i glanced over to my pfc and noticed the hand controller wasnt coming on

So what could be the cause of this? does it have a fail safe to not turn on if a specific sensor is disconnected? Could i have blown a fuse or something???

wierd thing is, this whole time, my battery wasnt even connected, so i really doubt it could be fried

someone please put my heart to rest!! i havent even gotten the chance to try it out yet!

How much power left in the battery? Most ECUs require at least about 7V before they will spring into life.

i'm not sure, i dont have a multimeter but i had it hooked up to my charger, and i'm currently charging it up.

it's a faily new optima redtop so it shouldnt be dead...

i'll try it again after a few hours of charging

Got any lights on the instrument panel when u turned the IGN on???

U can also check for horn, headlights etc. ....if not ur batt is dead.

all the lights come on, didnt check the horn etc though

BUT i just moved the battery to another car and it started right up

i also connected another battery to my car.... same thing, hand controller doesnt boot up...

man if this thing got somehow fried i'm going to blow up!!!

well common sense would prevail here, given you have pulled the whole car apart and all the sensors etc

it could be anything, check the basics, double check everything, trace everything, and use elimination

how on earth do you expect guys on a forum to help? if the car is in bits / sensors unplugged?

it could be one single wire causing it to not power on

well i just wanted to know if anyone knew for a fact that unplugged sensors would cause the pfc to not turn on

    • Hi all,   long time listener, first time caller   i was wondering if anyone can help me identify a transistor on the climate control unit board that decided to fry itself   I've circled it in the attached photo   any help would be appreciated
    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
    • The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.
    • No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
