Hi im kevin do you know if you have fuel or spark ? Has crank sensor ever been replaced

Customer: replied 8 months ago.
Fuel is available in the tank, i have removed all ignition coils and tested the sparks on each glow plugs
Expert:  Kevin replied 8 months ago.

Ok so you have spark ?

Customer: replied 8 months ago.
spark on each plugs is working
Expert:  Kevin replied 8 months ago.

If you remove airbox and spray a flammable lube inside whilst cranking does engine run ?

Customer: replied 8 months ago.
I haven't tried that yet, but somehow on that day when the day the car breakdown, the immobilizer tell-tale light doesnt flash anymore, central locking button isn't working either and hazard lights.
Expert:  Kevin replied 8 months ago.

Ok so central locking doesnt function from in car or just from key

Customer: replied 8 months ago.
both, the switch on the dashboard and the key fob
Customer: replied 8 months ago.
i even tried the spare key aswell
Customer: replied 8 months ago.
Replaced key fob battery, it's still not working
Customer: replied 8 months ago.
What should i check first to get the car starting?
Expert:  Kevin replied 8 months ago.

Keys are common but as spare doesnt work that rules that out .have you checked fuses

Customer: replied 8 months ago.
All fuses checked engine bay and under the dashboard, i even measured the voltage on the fuses 12.8volts for ALIM UCH and MEMO INJECT
Customer: replied 8 months ago.
But i am not sure which one is the "fuel pump relay" located at the engine bay fuse box
Customer: replied 8 months ago.
I have also cleaned up the TDC/crank shaft sensor, when i crank the engine the RPM meter moves up abit, so i guess the sensor is working
Expert:  Kevin replied 8 months ago.

Try some fluid in air pipe and let me know what happens and we will go from there

Customer: replied 8 months ago.

Expert:  Kevin replied 8 months ago.

Expert:  Kevin replied 8 months ago.
