This morning my Civic 1.4i had a starting problem for the first time in 9 years. It fired on initial start then died. It would not then fire. It was used on Sunday and temperature this morning was just above zero - so warmer than recently. Battery and connections in good condition, 64 miles out of full tank of petrol, starter turning engine normally. Opened bonnet and tried a few connectors but no joy. Then tried holding they key over for a l-o-n-g start (nearly 10 seconds) and it gradually fired up. Seemed like a fuel supply problem (but I do electronics not combustion stuff).
As wife was sitting in passenger seat, we had to go shopping and the next 6 starts were normal. I checked the OBD later but there were no error codes - would the good starts have been sufficient to wipe it? Google points to main relay/ECM problems but mostly in the previous model.
Any trouble-shooting suggestions for when it happens again?
