OK so I did a rebuild on my 02 Grand Prix gt and now when i go to start it it cranks but fires once and won’t run I’m assuming it’s a fuel issue (injectors). Anyway that’s not the main issue. Since I’m cheap all I did was pull the bearings,crank and pistons from a good motor I had (ac bracket hole was fucked) and put them in a diff block I had but now on top of the no start it sounds like there’s either piston slap or rod knock. Not really sure y.

So you didnt measure anything, bearing clearances, bore, etc.?
The rings were swapped along with the pistons?
You didnt check if connecting rod bolts or bearing cap bolts were torque to yield style?

Yeah I didn’t do any of that but torque everything down. Thought it would be fine for some reason
