Nissan Patrol GQ/Y60 & Ford Maverick
Usual 2.8TD glow plug woes, flashing light, no power to plugs, relays click on then off almost instantly. Starts eventually but runs like my dads old VB commodore till warm. Replaced all 6 (yes the expensive ones) 8mths ago.
Tested both relays - all ok
Removed the control box...
