12.2What is the battery volts
Dam12.2
I have checked again this morning.If you scanner does data logging
Log the
Volts
And
RPM
If the volts fall below 6V its getting towards the area where the ECU can not maintain the 5V reference needed for the sensors
Here mine falling to just under 9V which is fine
If the volts are fine but the RPM stays at 0 then we are looking at the connection between the ECU and Crank sensor or the already changed sensor

That great no signal, no spark, injectors never going to startI have checked again this morning.
RPM stays at 0
Is that with the sensor disconnect, multimeter on A/C volts and the car cranking, or just at ignition on.i have check the voltage on the crank and cam sensor. the crank shows about 2v
That exactly as it should beearth shows 0.2v (on engine block and earth point)
Is the ABS a new faultAfter I have reset the errors. now it does not show errors but the engine still just turn
The dash shows only these lights

sensor disconnected with ignition on and cranking. I have tested the cable only. still have to test the new sensorIs that with the sensor disconnect, multimeter on A/C volts and the car cranking, or just at ignition on.
this ABS light is showing since motor stopped working. Might this be the problem? This light stays on when ignition is on and cranking. does not go offIs the ABS a new fault
Also make sure you were supplied the correct sensor, check the length of the sensor against the original,sensor disconnected with ignition on and cranking. I have tested the cable only. still have to test the new sensor

the sensor is the same size and make. I made sure of that before I paid.Also make sure you were supplied the correct sensor, check the length of the sensor against the original,
Happened at the same time, have to think about this, the ABS is self contained, it checks itself at start up and if everything is okay it switches the dash light off via a command sent via the canbus to the body computer (BSI)
The ECU and engine sensors are also self contained it only sends information to the BSI to control the dash
They both use the BSI and dash. But the main connection between the ECU and ABS is the power and grounds?
Greatthe sensor is the same size and make. I made sure of that before I paid.
Finger crossed its not too seriousI got hold of ab auto electrician. he will come and have a look
We found the problem.Great
Finger crossed its not too serious
Not the no RPM signal faultWe found the problem.
Petrol pump, not giving enough pressure. when I put my finger on the pipe it does not give enough pressure to spray. We hardly feel pressure
we tested the pressure with engine cranking. Everytime we start, we could hear it wants to start and then just cranking. All for a sudden the ABS light goes off while cranking, and the error codes is blank.Not the no RPM signal fault
Not the ABS fault
There's little pressure in the line while the car not cranking, have you tried it while cranking?
What voltage at the pump
You have to have a crank single to the ECU for this to happen, we could hear it wants to start
