I know it sounds simple.....but .....as an Electronics Tech for well over 40 years this is the case more times than not. Make sure the coil packs are plugged in....check everything that was touched. Then look at plugs where possible someone pulled on the wire harness instead of the plug for removal and pulled a wire or two out of the connectors internal pins.
