I have uk spec grand voyager 3.3l v6 2002. Worked fine yesterday and has done for years but it won’t start today. No spark, won’t fire, all plugs and wires only 2 months old, battery 1yr, fuel in tank and pump sounds like it works. Got engine light flash 10 times at me when trying to start, and code p1685 came up on dash too. Tried the spare keys - no different. It’s not even trying to fire. Called out breakdown company but they couldn’t work out the problem either even with their computer attached. He said maybe pcm is dead. Other advice tells me to change crank sensor. Any help appreciated! Thanks
