Hello

If the car's not cranking then first check it can turned over by hand by using a socket on the crank pulley nut, so double checking for any mechanical issues

If OK then check that the main battery cables are on tight and the terminals are clean and bright. Do the same for the engine / gearbox earth strap.

Then follow the main positive lead back to the engine and down to the starter motor, and check the connection at this end as well.

There should also be a small wire to the motor which should have 12V when you're turning the ignition switch / pushing the start button to crank. If the 12V isn't there, check back along this wire for damage to the insulation or corroded connections

the code U0126 points to a loss of communication with the steering angle sensor behind the steering wheel, this should have nothing to do with preventing it starting

Before this issue i changed egr valve with egr motor. And when i erased learnt values of egr. Started the car normaly and after
1 minute it stopped. Also found leaks in fuel delivery system right before fuel filter. What i should do next? Already fixed the leak. Car starts after long cranking , but stops after 15 seconds. How to learn the car not to open egr valve after it starts?
UK Auto Mechanic: Matt, Mechanical Engineer replied 8 months ago

Hello

if the EGR valve is new then it should be OK, if its starting then stopping then I'd say to check for an air leak on the fuel supply pipe from the tank to the engine. The engine has no separate lift pump and relies on the built in one in the injection pump. If a leak has developed on the fuel suction pipe then air entering the system will air lock the pump.

Try pumping up the fuel using the hand pump in the engine bay on the filter housing, then crack off / loosen each injector pipe in turn while cranking the engine and getting an assistant to operate the primer. This will expel air from the injection side and the engine should fire up. The problem will be cured by checking the supply pipe along its length for signs of leakage and repairing any you find.
If you daub each pipe joint with heavy grease and the issue goes away then wipe the grease away one at a time to highlight the problem joint
