I recently blew the engine on my 2013 volvo s60 t5. I took it to my mechanic and he ordered a 2012 s60 t5 engine. He’s having trouble getting the 2012 one to work. He says it will start for about 5 seconds and then turn off. Crank and cam sensor engine codes are coming up and he said he’s already changed both of those. my mechanic says it’s troubles with the ecu and computer. what do you guys think? any possible solutions?
