Help! Injector install gone wrong

[hollister25073]

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

stupid question but are the injectors from a reliable source and with all new gaskets....

[hollister25073]

Yeah the are straight from alliance I bought my injectors through the same dealer as did the other sets

[helsel_182]

is it still acting like it is hydrolocked or did it only do it at first

[hollister25073]

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

[hollister25073]

Top tab on the starter was sheared off after a new starter and some priming cranks she fired thank god

Drained the rail on the drivers side install and is acting hydro locked again

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.

I spun it over by hand with the injectors out

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.
