Fiesta Mk7 starting problem ?

[J4CKO]

My Wiifes 2014 Fiesta ecoboost failed to start this morning.

Assumed it was battery and stuck it on charge, tried it just now and just gave a click, got out, rocket it in 4th gear back and forth and it started, turned it off, wouldnt start, did the rocking again and it started fine a coupel of times before I went back to work.

Any ideas, solenoid, relay ?

What should I try ?

Years ago cars were fitted with Inertia starter motors and they would sometimes stick In mesh, pushing more than rocking a car In gear would often release an Inertia starter motors pinion from the flywheel

Your car has a pre-engaged starter and rocking it should have no affect

At a guess, when you're rocking the car the engine is moving a little which is curing bad battery connections, a bad engine block earth or bad battery positive connection at the starter solenoid

It's also possible for a pre-engaged starter to become sticky. Also damaged teeth on the ring gear may cause the engine not to turn over when stopped in certain positions, though you'd hear the starter turning.
