Good evening I once asked myself a question to the professionals. I bought myself a S70 year 1997 last weekend.Bin driven highly pleased home, and beautifully parked under the carport. Then I wanted to start him 2 days later then went nothing more. He orgelt only jumps but not at. Motor 2.0 liter 126 hp. so I first checked the basics fuel ignition spark,air, petrol, timing belts = everything in order, did not find any martens harm. Nevertheless, he does not jump at just b I have read out the box (diagnosis device from a buddy) Conclusion everything Oke. Only one thing no communication with the engine control unit possible. Ignition spark on the ignition plugs but still there and he injects one at the start. Could it possibly be on the diagnostic device (laptop with adapter and program) that is no communication is possible or has a good idea what the good one could have. Have also already all safe He’s only 104,000km down Thank you very much for your efforts.
