44 Initial Starting Procedure
If the Engine won’t start
Check for correct fuel pressure.
Check for fouled plugs.
Re-check for diagnostics errors.
Re-check the Ignition Timing with a Timing Light.
Check the setup parameters against the drawings.
Check that the ignition is wired in the correct firing order.
Check that the ignition is firing on the compression stroke, not the exhaust
stroke.
After Start Checks
Ignition Timing Check
Check the Ignition Timing with a Timing Light to ensure that the actual Ignition
Timing corresponds to the ECU Ignition Timing as shown on the ECU
Manager : View screen. Check the timing at high and low RPM to ensure that
it is correct at all revs. If the timing is correct at one RPM but incorrect at
another RPM and the REF sensor is a magnetic type then the trigger edge
may be incorrect or the sensor may be wired in the wrong polarity.
Adjust the setup parameter CRIP (Crank Index Position) to correct for small
variations in the REF sensor positioning.
Adjust the Ignition - Individual Cylinder Trim for cylinder number 1 and
verify that it changes the ignition timing for cylinder number 1 rather than any
other cylinder, if not then the CRIP is incorrect and needs to be adjusted by
multiples of the angle between cylinders.
Fuel Pressure
Check that correct fuel pressure is maintained under all load conditions.
Operational Diagnostics Errors
After the engine has started check for diagnostics errors.
To clear any non current errors press the Enter key while viewing the ECU
Manager : Diagnostics Errors screen.
The following operational errors may occur in a new installation.
