Help! Injector install gone wrong

Started doing a simple injector replacement on my buddies 7.3 excursion and did the passenger bank tonight got it all done and now the engine acted like its hydro locked so I bared the engine over and it moves fine and now when I go to start it it makes a horrible racket I hope the starter just took a dump from it hitting a stop but I hope someone has an idea what it may be I've done 4 full injector replacements on 7.3's and never had this happen and never drained the rails prior to removing injectors

Now it will crank it just makes a horrible grinding sound so I'm hoping it's just a starter

You need to pull all the glowplugs AFTER installing new injectors and spin it over until there is no more oil and fuel in the cylinders (it makes a mess,but spin it over with the starter until nothing is blowing out the GP holes). It's acting hydrolocked because it is hydrolocked. Be careful, you can and will bend a rod if it starts with liquid in the cylinders.

well that isn't even CLOSE to good enough. You NEED to spin it over WITH THE STARTER with the injectors installed, but the glow plugs out. I guarentee that if you remove the GP's, unplug the UVCH, and spin it over with the starter, you will get a geyser out of the cylinders. Spinning it over by hand with the injectors out will not get enough of the oil and fuel out of the cylinders.
