Help...!!!!!

[TonyN]

Well thats the last time i wash me truck if its gunna kill the ecu.

lol, it shouldn't, if you have just by washing, it, you're the unluckiest man in the world, and i wouldn't bother doing the lottery any more..

Make sure it is before spending big bucks on an ECU, if its just the immobiliser or something.

Have you checked the ECD fuses and relays?

[Paul1566]

Been through every fuse i can find.

Going to send ecu to ecu doctor for check.

[charvell]

Have you disconnected the immobilizer? As Tony said its unlikey to be the ecu, its more likely a wet connection and you have not found it yet, there are fuses in the engine bay and the in the drivers footwell.

Its been drying out since sunday and its been quite hot here.
Found wiring diagram and going check the supply is getting through to the
ecu when the immob is deactivated.
Just seems really stupid that just washing it causes so much agro
the ecu is bone dry in the nearside footwell and the alarm is in the offside footwell and no water got near that.
Cannot see why getting a sensor contact wet causes it to do this, does it mean i can't drive through deep puddles or in the rain for fear of it stopping.
I'm ranting now cus is really miffed, it was going so well...........

Pulled off and checked connections blew dry with me supped up bike dryer.

Any form of blow dryer will rarely shift water unless you get everything uncomfortably hot. Use an air line and gun, isopropyl alcohol or something like WD40 to displace water from the connections.

Btw, have you checked the fuses for the immobiliser too? They are usually on a separate block to everything else.

[Paul1566]

Just been reading the downloaded wiring diagram and will check me immob is letting power get to the ecu tomorrow.
Its letting the charge circuit complete cus the light comes on for that.
Must say surf wiring is like spaghetti its everywhere and tight as chuff to get at.

Missus kept on about doing the scotland trip this weekend, good job we didnt get round to it as now i've buggered it up she'd have killed me by now......

[Paul1566]

Went and checked i have power going to ecu after immob is deactivated and it was there and switching with the immob so must be the ecu.
Bugger bugger bugger......

[POPEYE]

Dunno if this helps but when i stripped down all the stuff from my engine to do the painting i found one wire going to a plug on top of the IP that was nearly severed, it was only connected by a couple of strands, thinking perhaps if your's was in a similar state it may have parted dureing cleaning,
as said a good going over with an airline with a blow gun on get rid of water.moisture much better than heat, if everything was ok before you washed it it has to be water ingress or broken cable, hope ya sort it ok

[Paul1566]

Cheers Popeye, i just cannot see how water ingress can completely stuff a truck up thats been driven through mud and puddles no worries then clean her and she dies.....didn't even use pressure washer just rinsed off with hose.
Also seems strange that if it was a loose wire why doesn't the ecu flag just a loose wire using the engine check light and codes....??????
Well if i send my ecu to be checked its £30 to test and if ok then i know to look else where and that my ecu is good.

The blower i use is not yer average hair dryer its a converted dyson that blows harder than a hong kong hooker and it shifts water real good.
When we wash the bikes we blow them down with the blower and its amazing where water comes out from, saves the streaky paintwork problems and is better than a chamois.

[Paul1566]

Just found some great wiring diagrams for the 1KZ-TE and KZN130 so will be doing all the voltage checks and resistance checks tonight on my ecu.

[Paul1566]

Well not sure if you give a monkeys as i waffle on but i am going to keep you all updated on my "how not to wash yer surf" adventure. Not as exciting as Apaches adventure but non the less a damn good read.
Found some great info and me and the girl went out and did all the tests on the ecu. Will post the link to the info later.
Through up a wobbly on the power circuit there is only 1.5v on VC when it should be 4.5-5.5v and as the battery is 12v i assume this is a supply from inside the ECU. God knows what VC means but it not right.
Something to do with supply to throttle position sensor just been told......
Immob supply was fine and switching so i ruled that out.
Gunna post it tomorrow and get it the swine flu jab from ecu-doctor......

Had to take the bus today, guy sat at bus stop 8am and he's into a can of special brew and his tab smelt rather nice. Halfway to cheltenham clickhiss and he's into can number 2 and he's on his way to work security card round his neck....... bus driver was pretty good for a poledriver.....

I MISS MY SURF....AAAARRRRGGGHHHH!!!!!!!

[gwh200]

Have a look at the wiring from the tps .........this needs to be sending a signal to the ecu to increase the voltage to the pump
and get yourself a can of "spesh" for your next bus journey

[Paul1566]

Whats a TPS when its at home..... igot brain farts for tea.....

[gwh200]

Do a search for throttle posistion sensor......all will become clear

[Paul1566]

Ok searched for TPS and did all the checks and read sooooooo much it hurts but no luck.
Packed its brain off to the doctor this morning to get a diagnosis.
Why the hell does the surf need a brain it should be a bit more ruffty tuffty.
What would you do if her brain went in the middle of your pyranean trip and she refused to give you glow and fuel ????
I did toy with the idea of hotwiring the fuel supply and then decided not to cus my missus said i'd probly fudge something else up.....
All her other functions seem to work with out the ecu plugged in, even cranks on the key with ignition lights and all.
Suppose you could jerry rig the glow plugs on a switch and then some how
fool the fuel cut off into opening.......
May be worth investigating incase it does hapen in the field as a get me home.
