typically, the 1345 code is either the cam sensor, the crank sensor, distributor is off, or timing chain jumped. unfortunately, it can cost a bit to figure out. first step would be to have a dealer read the cam/crank offset. this needs to be set to 0 degrees, + or - 2 degrees. you could end up spending money on sensors that don't need replacing, when it just needs a quick adjustment of distributor. now, a distributor drive gear worn out could cause this code to. generally, if the cam or crank sensor goes out, motor won't run. i'd have the cam offset, also known as cam retard, checked. go from there.
