Check and make sure all grounds are reinstalled properly.I have run across issues with loose,corroded or poor connections with grounds as some bolt to the back of the head or block.Make sure all wiring is o.k. and no wiring was pinched or damaged in any way.
If this is all o.k. let me know.

The engine is grounded. I checked it with a multi meter. I have spark on all cylinders checked with an induction timing light, but it is weak, I have fuel, it cranks and stumbles after sitting for awhile. I have some combustion, because the new plugs are a little dirty with carbon. Checked the ecm ground distribution and all seems fine, according to Alldatadiy
I apologize for the delay.
Have you done a compression test at all?
