Trying to change my oil pump and timing chain. Only issue is the crankshaft pulley refuses to come off. I bought the Lisle puller remover for 3800 GM engines but the bolts that come with it are too small. What size bolts should I use? I've included a picture of the pulley.

Good evening,

There are 2 pulleys.

One uses 6 mm bolts and one uses 8 mm bolts.

From the picture, I would say you have the 6 mm bolts.

I'll check that out and let you know. How long should they be?

Now here is the real question: should I leave the bolt on, just screwed in a little bit or take it off?

It depends on the puller. If you have the adapter with the shape of the V at the end, you can remove the bolt as the V will not contact the threads.

Otherwise, leave the bolt in a couple of threads.
