I just had mine out last week. It is very diificult to do it in the car. Removing the injectors will help. You can shine a light down the hole while someone turns the shaft. it wasn,t easy. The bolt came out of my pump while I was at a light. It took my a while before I found the problem . the pump had to be remove and I was very lucky there was no other damage. I set timing to 14 after and it now sounds sooooo quiet it makes me nervous.

Oh do not tighten the lock screw until your sure its engaged.
