Motor won't fire........
 

I did a 2002 to 2005 Nissan altima motor swap hooked everything up.....now I can get the motor to turn over but it won't fire. Any ideas of what might be wrong...? Any help is greatly appreciated!!!

Swap computers also? May need a reflash.

I didn't swap computers I cand find my computer to flash it

2002 computer may not be compatible with the 2005 engine for some reason? But would think if all connections were the same,hooked up right,it would at least try to run. Think you really need to pick the brains of a Nissan tech on this one.. http://www.justanswer.com/nissan/

I'm not paying 20 bucks for an answer I have no clue if it's right

Okay,how about free service manuals that may help you track down the problem.... :) 2000-2005 Factory Service Manual available for download, free, no gimmicks - Nissan Forums : Nissan Forum

Figured out I set the timing wrong.........

Yep that can cause a problem or two.. :) Glad you found the problem.. By the way are the cvt transmissions pretty dependable on the Altimas? Seems like they ought to be as many years as they've had em.. See enough of them on the roads.

From what I've seen and heard yes they are very dependable
