My check engine light keeps coming on and when I pull the code it indicates the engine ran lean for more than 15 seconds. I recently rebuilt the whole top end, so my question is what could be causing this?

I noticed the injectors are batch faired, but I'm wondering if they fire in two seperate batches of three each, or do all 6 fire as one batch? If they are two batches that might be my problem, since I have no idea which batch the two middle injectors are supposed to be plugged into, since they can be plugged into either batch. Any ideas??

Edit: Sorry, it's for the 2.9 litre, I hacve a '92 supercab 4wd
