[v6 steve]

can i just warn you all if you do come please beware of my mother i had to move back with her a year ago and she rules the roost but shes a good cook

dont worry maate we all have mother's

Is this going ahead on the 30th?

I've got my grubby little mitts on a Snap-on diagnostic scanner for the week, which might or might not be useful...

[Mark1]

Mate of mine had one for a couple weeks and it never worked on the V6.

[v6 steve]

Mr C got a snap on one and it never worked on the Drain we weren't sure is it was something to with my piggy back ecu tho

Markv6 rich has someone looking at it this week and if he cant help hes going to give us the green light and it would be next Saturday 30th for us

iv got some1 coming to look at the v6 on tuesday but if that doesnt work you are all still welcome the more the merryer in my eyes i will let you no

mark its worth a try if you ask me

[Fraz]

always thought it was because they never released the eprom for the M2.8 software (or some such thing) get a Tech1 would be handy

right iv had a kid round with a diagnositic system and he comes up with code 31 and code 93 (when trying to start the car ) he said to check the voltage to the cam sensor but we dont no what volts it should be any1 got any idear what volts should be going in to the cam sensor from the ecu thanks

[MarkV6]

Looking at the wiring diagram,
Terminal 87 from the fuel pump relay feeds pin 1 of the cam sensor, Pin 2 goes to pin 8 on the ecu connector, pin 3 on the cam sensor to ground.

Taken from http://www.v6calibra.net/motonic/v6calibra_motronic_faultcodes.htm

93 : Hall Sensor - voltage low CAMSHAFT ANGLE SENSOR (P47)
EFFECTS:
Engine load signal is greater than 3 ms and coolant temperature is greater than 38 °C (100 °F):
The control unit retards the spark timing by up to 10.5 °CA for reasons of safety.
(Value varies depending on the engine speed)

The "Hall Sensor" on the camshaft is used for cylinder recognition. It informs the Motronic ECU of the camshaft position when cylinder 1 ignites. The ECU needs this information for accurate fuel injection control and for adaptive knock control. If the Hall sensor malfunctions the ECU attempts to use a random time for injector/spark actuation. This can cause a poor or non-starting engine. If the engine does start with a malfunctioning cam sensor then expect very poor economy.

ECU Terminals:
8, 19, 37

TEST:
with engine running 2.5v DC (average)

right then still no look so if any of you want to come down tommorro and have a look i would be very greatfull of the help

[MarkV6]

Been called into work today, so can't make it.

The only other thing I can think of at the moment is it's a blockage in the exhaust system, collapsed cat/silencer baffles. Did you notice any change to the exhaust note when it was running??

Get someone to try to start the engine whilst you hold your hand over the exhaust to try and gauge the pressure of air coming out. Then compare it to a car that starts.
Get under the car and hit the cat and silencer boxes, if any rattle then something is loose inside and could be the problem.
You could try unbolting the cat from the downpipe, then trying to start the engine.

After all the electronic ignition parts/sensors you say you have swapped and replaced, it's the only (cheap) option left.

well ordered a ecu lets see what happens next

wrong ecu the t****r said it was the same code number as i read him

[v6 steve]

Is it not a v6 one? You will need the transponder and chip too

[rich30mex]

It's come from a same year v6 as mine were is the transponder and chip located

[v6 steve]

The chip is in the key and the transponder is on the steering colum around the ignition barrow all 3 have to be from the same car or you'll need a tech 1 or similar and the pass key number so you can reprogram the chip
