Hello I will help you with your question,
The P1345 means the cam/crank offset is more than 2 degrees. You need a scantool that can display the offset and move the distributor until it is less than 2 degrees. Each time you move the distributor the engien speed has to ba raised above 1500 rpm for a second or so to reset the reading.
Once you get the code clear then you should be able to drive it to run the onboard tests.

Yes, as long as they have a scantool that reads the cam/crank offset. Most of them do and it is a simple adjustment to get them in sync.

Are there any other codes being set?
The rest of the testing procedure should run, it may take extended drives from a cold start to get everything to run.
A drive cycle is from a cold engine through about a*****in changing conditions with some medium speed cruise along the way. If you follow that pattern a couple of times then the rest of the tests should run. If they don't a code will set or be pending that will point to the reason the tests did not complete.
