I recently bought a new rebuilt 4.7 from YamatoPW. Sorry in advance if this sounds stupid, but my question is this:

Does the motor have to be at TDC before you fire it? Im not sure how these coil packs work with the computer, but I dont want to ruin a $2600 motor. Do these self time? I was going to call them tomorrow, but I thought I would ask. Thanks in advance

 

There are camshaft and crankshaft position sensors. The computer will know. You shouldn't have to worry about putting at TDC unless you changed timing chain or cams.

 

Thanks HemiLonestar. I thought the computer might pick it up Going to try and wiggle it in today. I will post some pics later, thanks
