Re: 95 vortec ecm fuse
P1345 is "crankshaft/camshaft sensor correlation". What this means is that something is not aligned exactly right. It could possibly be that the crankshaft sensor is misaligned in its bracket, it may be loose, or it may be crooked. Other possibilities include the timing chain is not correctly timed, (off a tooth) and/or the distributor gear is not timed correctly in the camshaft gear, (off a tooth). P1345 is not a common fault code and it’s typically triggered due to basic engine problems. Your best bet is to obtain a shop manual and follow the flow chart for this DTC.
