New coils, still weak spark, no start
#2
Did it run before you did these repairs? Or is this a non-running vehicle from the get-go? Did you happen to smell fuel when the plugs were out, and what did the old plugs look like, coloration wise? What's the condition of the battery, is it turning over strong...if the battery condition is poor...the amount of power will be reduced to coil packs on account of amperage draw from starter.

Are the lean codes throughout the engine, both sides? If so, I'd be checking fuel pressure. Are you checking spark with a spark-tool/ gauge or just looking at the plug? If misfire codes are only on one side, might be an 02 sensor issue...but l would think it would start. Were the removed plugs white-ish in color? What were the codes exactly? You could give it a little snort of ether and see if she starts (after the MAF sensor, right at throttle body). If it starts on ether, then you can follow up with diagnostics on fuel system.
