Sean 2.5

Hi, New member here! My 2002 x-type 2.5 petrol, purchased new and with only 80k mi, is not starting. The car was in storage on a battery tender for the past month. Initially after taking it out of storage the car started and ran for ~30mins but after shutting it off, it would not restart. - Battery, alternator, & starter are all good (confirmed with local shop) - No error codes It feels like an ECM issue, any suggestions? Best, Sean
