Ford S-Max starting problems

We had issues with it starting a few weeks ago now every morning cold starts is a problem the engine cranks catches then cuts out ...... once started all ok all day.

When was the fuel filter last changed ? Could also check heater glow plugs are all operating A good , correct type battery is important also

Hi. the fuel filter is brand new service dated June 2020. When starting it struggles once started knocking noise, then settles after 2 to 3 mins drives well all day. no other problems no warning lights. Glow plugs changed last week also has new glow plug relay.

You tested each glow plug is working and got power ? Not the first time there have been wiring faults . Has the car done a high mileage ?

Wiring loom checked there was a break in loom from shearing against the auxiliary belt which was repaired my an auto electrician and no issues with power to all glow plugs as this was checked. mileage is 106k, purchased car in june 2020. Is there any fuses in the engine bay worth checking. if so where do i find this.
