I had this a couple of weeks ago with my 2015 GDI and called the AA out. Fuel pump worked, click but no crank. All electrics fine and full battery. He spent a couple of hours on it in conjunction with a very experienced Morgan owner/ auto electrical expert giving a second opinion over the phone but to no avail. Everything was checked including earths etc. He came to the conclusion that it must be the immobiliser kicking in when it shouldn't. I tried both keys to eliminate them.
Anyway, the Morgan expert kindly came down the following day and took the fuse box apart checking all fuses, relays etc. After some handling of (now bear with me as I have zero technical knowledge) the connector housing that all the wires go into and subsequently plugs into one of the control boxes (not the ECU one I don't think), the car kicked to life and has been OK since. Coincidence? Maybe.
The suggestion is that possibly the pin/wire which controls the immobiliser may be loose or faulty and that is next to be looked at to eliminate it, but at the moment the car is working.
A few years ago I had the same problem with a Freelander and off it went on a truck to the auto electricians but when it was taken off the truck at the other end it fired up and has been OK since.
Maybe it is the same Gremlin!
N.B. This came after driving 200 miles from MOG 18 in soaring temperatures then left in a very warm insulated garage for a week before starting the car again. Maybe there was some expansion/contraction of rubbers/plastics in the connection housing that caused a bad connection. Unlikely but just a thought. I had the same with my Freelander a few years ago. The RAC man came out and fixed it straight away then showed me the trick. It involved a screwdriver and hitting something. Trouble is I can’t remember exactly what but it might have been a relay.

“It involved a screwdriver and hitting something”  Possibly the TM quote of the month? Brilliant

It was a quick fix in the end ...it was flooded!
Could anyone recommend a decent plug spanner? Mine we either too wide to go down the hole or too long so they hit the bonnet hinge. If it happens again at least I will be able to take the plugs out if I have one that fits.

Glad they got it sorted out - I've got the V8 and the standard socket suits me so no help to you on that score, others will be along soon.

Nissan Micras ( older style) suffer with flooding too if started and stopped before warmed up. Quick way to sort is -
Remove fuel pump fuse or relay - crank car until it starts to cough into life - replace said fuse/relay and off you go.
Works well on most modern cars where flooded. Trick is knowing its flooded i guess.
Note - doesn't apply to flash floods caused by global warming or cows farting!

I can tell a lot about problems with flooded older Micras if they where stopped before warmed up. It meant to make a short trip if the car only had to be moved some m.
