After removing my engine to fit the gtb2260vk and had a few other things done headgasket and bigger injectors fitted the engine back in and tried start it the glow plug light is flashing and the brake warning light and the car just turns over doesn't even try to fire any help would be appreciated

I'd start by going over all electrical connections in the engine bay unplug and plug back together make sure they click back in. Double check the large one in the side of the battery as this is something to do with the glow plugs

Cheers mate will double check that plug by the battery
