Customer Question

2003 Ford Mondeo 130bhp 2lt TDCI
Replaced flywheel and clutch over the week by a friend.
Car was also serviced at the time (air & diesel filters..etc)
Everything was put back together, but they car wont start now (It is trying to turn over, but wont actually start)
Have rang the motor factors and they confirmed that the flywheel is correct.
What could be causing this issue?

The mechanic/friend noted that on the origional flywheel there were 2 weights/balance but on the new flywheel there was 1, does this seems right?

Hi there
Does the engine turn over fast enough it is it sluggish
Has the crank signal been monitored using an osilliscope

Engine turns over fast enough.
Don't have access to an osilloscope so can't check that.The mechanic/friend noted that on the origional flywheel there were 2 weights/balance but on the new flywheel there was 1, does this seems right?

Hi there
Ok I havent noticed the different weights you speak of but have had issues with non ford flywheels that have arrived from other garages that have had flywheel/clutch repair carried out and wouldn't start
We are fortunate enough to have software that can monitor weather the engine us syncing up (cam and crank signals)
If this shows no on our datalogger we can then scope and monitor the crank signal using an osilliscope
The fact that the vehicle started before the flywheel was replaced gives avoiding stood that this is the most likely source of our issue
Iam assuming all the earths at the battery support test are all refitted (if removed )
Is There any fault codes logged or glow plug lights flashing

There are no lights on the dash..
Could it be a sensor on the crankshaft?
Mechanic is back this evening, anything we should check??
Expert:  Gallagher99 replied 1 year ago.
Hi there
I would bsusiecting a crank pick up issue
As the crank sensor picks up the signal from the flywheel teeth
Ensure the sensor hasn't been caught when refitting the gearbox or the wiring hadn't been trapped as these are all common things to check for
Next step as I mentioned would be an osilliscope test on the crank sensor
As I have seen non ford flywheels cause starting issues

Car has started and is ticking over.
It seems to be very spluttery now so possibly air in the diesel lines?
One funny thing we noticed was the speedo seems to going backwards?
Any ideas?
Expert:  Gallagher99 replied 1 year ago.
Hi there
I did suspect air ingress from the filter change thus why I asked if it has hand primed as these can be difficult to start if not primed correctly
I would give it a good run then switch it off and restart it
The speedo can sonetimes do this if the battery voltage has been spiking or ecmxcessive cranking
Regards Brian
