guys... have had my vvti 1j soarer in the country now for about three weeks, it's been fine driving around but yesterday it just sorta..
...stalled. near my house..
then on the way home it stalled again.. got home, and just ran it at idle for about 8 minutes.. stalled again.
now every time i try start it - the start motor goes, engine starts for 2 seconds, and then it DIES.
this symptom is commonly looked on as being the fuel pump ECU.. everything of my symptoms pointed to fuel pump ecu.. bought a brand new FP ecu from toyota and plugged it in... nothing..
still won't crank.
i've also ruled out the following:
fuel pump
fuel
throttle position sensor
vaccum hoses
my INKLINGS are the following:
MAP sensor
factory toyota immobiliser
main ECU
thoughts??
btw - specs on my car.. late model vvti soarer
no engine mods
full service history
105xxx km
virgin motor
i'm REALLY hoping someone on here can shed light- i'm LITERALLY at a total loss as to why it's not working =( |

update: i know there is a 1jz vvti corner in the TT mechanical section but 1) i can guarantee this is a common soarer issue and 2) i am pretty convinced it's not mechanical!!!
i'm going home now to plug in the MAP sensor from my dad's car and possibly try his ECU..
..im tearing my bloody hair out here honest. =( |

When you say it won't crank, we normally take that to mean it's not turning over at all. Think "crank handle" .
Is that your meaning? |

yeah nah sorry that was probably poor choice of wording haha when i said cranking i meant it metaphorically like "oh that things fkn CRANKING"
okay
so - turn key.. right??? start motor starts..
KkrRRRrRRrrRrRrR.. then engine starts..
brooommmmmm...
thennnn after about two seconds maybe three if it's left for a while..

i assume so.. i (have heard) that vvti soarer have proximity immobilisers in the key..
bloody hell only YESTERDAY i found the screen meanings for the Lpack soarers.. now i cant find it for the life of me! 
okay ust tried the MAP sensor - it's definitely NOT the map sensor either..
i thought it may've been the immobiliser myself - especially given that A) the day after i got my car my remote central locking stopped working and B) my parents remote can lock / unlock my car - meaning it's coded the same..
meaning central locking originally worked on both our cars, but then after the second time we used central locking - low n behold the OTHER soarer key started locking n unlocking my car - and subsequently MY key fob stopped working on it..
i thought there was a possibility the ECU had trained itself to read THEIR fob.. instead of mine..
but i rang ashley electrical (for those that don't know, these guys are WA KINGS of immobilisers) and they said there was no way this could've happened and that it's the MAP sensor.. well i ust proved that theory wrong..
WTFFF!!!!! ARRRRGGGGHhh
okay so i'll upload an image of the Lpack screen message |

okay doodz here it is:
^^^WHAT THE HECK DOES THAT MEAN!!!
there was a link of a fairly ancient soarer site that deciphered these codes i was looking at yesterday but now i can't find it..
anybody have a spare bullet i can chew on? |

hmm, so you reckon it may be the ECU???
where's the main ECU located?
i'll plug my parents' one in see if that fkn works
hope it's not main ECU |

what's a wallet key? there's a key with no head that's in a sleeve of the owner manual, is that what you mean? if so how does that fix things :-S and yes I think it's immobiliser too.. but difficult to prove that |

MAP sensor??! The VVTi 1J's run an air flow meter/MAF sensor whatever you wanna call it... try giving it a clean.
Mine was doing something similar a while back so I decided to clean out the air flow meter and throttle body, makes a bit of difference. Mine has the stock auto and was able to chirp seconds once I had it cleaned out (and subsequently the single pegger shat itself lol). |

Hi Rowan.Try the following.
1.) Check the negative battery terminal make sure its secure and there is no fractures on the negative side of the battery.
2.) I personally think its the fuel pump ecu.Open up the hood,at the diagnostic port connect FP and B+ together.This will override the ecu.If the car runs fine with FP and B+ connected.then its your fuel pump ecu.
try this if it does not work then ill post new
message to run a full diagnostics which you have count how many times it blinks on the screen and then match the number from the 1jz error code which i have here at home.This should help us narrow the fault |

If you have a wallet key ,the one with no head try it, if it turns the engine over you do not have a immobiliser (lucky to get over pits without), so its not that, Sadesh idea is your best bet ..it has to be sparks or fuel. |

ive bridged the fp ecu already that didnt work... tried brand new fp ecu that didnt work.. tried original / old fp ecu still didnt work.. ive pretty much tried the negative terminal on battery with no luck.. ill try it again but yeah..
if ecu works im at a total loss.. I may have to get joe to diagnose it with me but yeah going nuts here.. will try wallet key too |

okay turns out a few things - the connector on the battery terminal was a LITTLE bit corroded.. which i sanded off..
tried it - it actually stayed on for about 8 seconds, got up n running n all then died again..
tried that wallet key idea.. engine turned over.. and ran even more than before - about ten seconds - even got to complete whole check on the Lpackage screen..
this shows that i A) do not have an immobiliser and was lucky to get over pits. as dave said - but luckily now understand the importance of getting an immobiliser..
regardless - problem is STILL happening.. i'll try REALLY bring up that connector - i know it seems primitive but can't hurt!
haven't tried the ECU - pulled up the carpet in parent's soarer.. didn't want to butcher it too much but is the ECU under the black plate?? there's a black plate beneath where passenger would put their feet.. |

Yeah man that's a cover, ecu under. Mine had a similar prob when I turned on and put 100% down On accelarator it would die. Took it to Joe and he replaced the maf sensor thing.
Another time similar prob and it was the pipe with the bov coming off under pressure. |

Have you tried disconnecting the air flow meter and start engine ?(i know you changed it)
Check all sensor wires cam+ crank (for rubbing ) ETC.
How old is petrol ?
is the fuel flap still working ? (has it got power) |

Rowan when the car starts and runs for few seconds does the engine sound smooth or rough.?
Have you checked the the crank sensor.? |

wow guys seriously i woke up at 830am western time been working on the car for an hour and i'm soooo appreciative of all your advices, seriously i cannot thank you all enough..
however - i've found the problem. it is the main ECU.. plugged my parents in and it works great..
now a few ways i can tackle this problem.. i noticed when pulling my connector looms out to swap the ECU that one seemed to pop out a little too easilly - so i'll try my old ECU first with the connectors RAMMED in - if that doesn't work..
i'll try KYP for a 2nd hand one
if they don't have one - i'll get a quote from toyota see what they can offer..
if they can't help / it's too exxy then i'll contact aaron get him to fly me one over from japan - i saw a brand spanker on YAJ lastnight $570 flown to my door..
so that's not too bad at all..
thankyou to ALL who've helped with this sorry for the urgent matter of this but as you can understand this is NOT the welcoming i expected on my first day of registrated soarer ownership |

okay thanks for more advice - FYI - KYP auto guaranteed me they had the right part but they were accidentally telling fibs - they seem to be very good at that - im sure they dont mean to be fibbers though
naughty kyp.
anyway they had HEAPS of TT ecu none of the ones i need.. gonna take apart my ecu and replace capacitors becuase that seems to be my problem |

okay so the plot has thickened.. pulled the ecu out to have a nice look at it - low and behold it seems i've found a problem..???
^^^THERE!!!
second pinout from the left.. what is that brown gunk?? it looks like battery acid - feels oily. this substance is all over the wires and the connector looms too.. and even on the floorpan.
does this mean leaking capacitors? i'm SO CLOSE to fixing my damn car if this is the issue.. |

okay for those of you playing at home - the substance was ENGINE OIL..
what the hell would ENGINE OIL be doing in there??
there's a slight pool (not pool - more of a "film") at the floorpan there..
by the looks of things there's oil in the connector part, i'm assuming oil's gotten onto one of the connector pins and it's making the connector... not work.. properly.
which is teh suck.
i have bought a whole new set of capacitors to replace the ECU whilst it's out of the car - who knows - may come in handy one day.
but how the hell would OIL be down THERE???
i mean im ASSUMING it's engine oil - it looks feels and smells like engine oil.
:/
but that would also explain why my parents' ECU works - no "substance" build up on their connector pins :p
can anyone suggest ways to get it off?? or clean it?? naturally my thoughts are to use detergent (obvioulsy this gets oil off) but i'm worried detergent will corrode the pins..
thoughts???
do you think the oil on the pins would have damaged anything in the circuit board? |

okay so according to this thing called the "internet"
oil is a very strong insulator - and i think that for whatever reason the oil is there - it's causing the pins to insulate and not connect - eeeexccellenttttt
now - something that's as fine and precise as ECU pinouts begs the question - how the fk do i get it off!?!
ps - i know you're all thinkking - my biggest concern should be "where the fk is the oil coming from"
and i have check high low left right up down inside out - i see no leaks, no lines, no trails, no evidence what so ever of any oil leaks there... it's just... there..
and what ever amount has been there has just sorta - done this... but it's all cleaned up now..
i have certain suspicions but not getting into that.. |

Try not to handle the board unless you keep your self earthed , static can cause damage .

Maybe someone had dirty hands that previously had the ECU out.

i don't know what toyota use CAS as an ackronym for but nissan says it's computer assisted steering :p
sooo if that's what toyota use it as an acronym for then i can guarantee you it isn't that!!!
as i said - plugged in another ECU in and it worked fine..
tomorrow day im taking my ECU to get new caps soldered in and getting them to check it all..

So in the end it was pretty much a common problem right? Cos I remember reading somewhere that even the TTs have the capacitor issue and require replacement.

"releived" isn't the word...
i'm currently in talks with websters a merriam's dictionary to create a word in the english language that will describe how i feel about it...
..so far we've come up with:
Releiwesomelexed - (adj) - When you are reived, and relaxed to levels of awesome (sic- see "awesome)
"Rowan was so releiesomelexed once he got his soarer going again for $110 fix" |
