Shutting Down Problem

[robbo k]

im at the end of the string with my 6t. after being well behaved for about 2 weeks n thinking every thing was sweet as candy it come back like a rash. the F**kin thing (that's what I call my car now) turned it self off hmmmmmm about 16 times in a row....... n by that I mean driven along 60kph 4th gear bang dead clutched it got about 10m gone again. then by that time I had lost my roll so pulled over turned the key crank it revs hit 2rpm like norm but then just drops straight back to 0 with in like 1 seconds of turning the key. now I have replaced a oil temp sensor goin to try the oil pressure switch.... (I do get 4 warning beeps but 10seconds afterwards) ford has had computer on it and said to replace the ecu cos it might be fried....... in which I was thinking if like a computer if you fry a motherboard the hole lot goes am I right??

oh and I have replaced the tps to which im thinking of replacing again. and it did let out a backfire when I clutched it

I was told can buy a 2nd hand ecu from a smash cos then would have to send to ford to get my vin number put onto it... so then I pondered if I was to buy a flash tuner run a generic tune would that clear it up?? or buy a phoon motor n ecu ??

I have been looking at all the earth wires to make sure nuffin it gettin tripped out

IF anyone has ANY info or advise on what it could be would be awsome. as I dont wanna put my 6month old in my car till it is 100% fixed.

car info 02 6t, 5spd, 100 thous, no mods.

Mate,

Take it to a real mechanic, not a "factory trained technician" as they know SFA about your car.

I would bet it is a blocked fuel filter or fubar fuel pump.

check the 4 big plug connecters next to the air box they give trouble sometimes, unplug them and check for corrosion etc.

the ECU's do give trouble so fraud may be on the right track if so id go a new one

dont go the phoon motor just yet as ull prob have to put all your sensors on it and you may end up with the same problem

also the transponder keys some times play up, if you have a spare key try driving with that one and c what happens

cheers dude

goodluck

You could try a generic tune but really at the end of the day who knows if it would work

when fraud (in SA anyway) get a prob like this

might be differant in other states but!

Can you even start an XR6 with a fried ECU?

[Mike XR6T]

depends what goes wrong with it, if its am ic problem you can get all sorts of weird faults

transistors can blow up causing an injector to drop out etc

lots of differant senarios

what they mean by fried is its screwed in one way or another

yeah I had it at my machanic n then he rang his mate at fraud to bing the laptop up n come up with the replace ecu. n then I took it down to fraud n got the same msg. my mate said half the time the computer wont even pick up a fault n said half the sensor n other bs they put on cars is a waste of time. I might try my spare key also what is the key with blue on top of it??

I have replaced fuelpump relays ignition relays, fuse.

when was one the computer it logged no fault codes at all bar replace ecu. they did ask if I had jump started it I did once but had it earthed off at the lifting point on the engine. maybe persone b4 maybe went straight from + to - on the battery?? but I can see how it can fry it

I have also been told that could be something to do with the ignition wires somewhere. and that some AU falcons had trouble with the ecu's......

Check the head temperature sensor on the rear of the head. It is also used to shutdown the vehicle in an overtemp situation I'm quite sure.

Did you ever fix this mate? Cheers.
