Well, yesterday sucked.
Flow-matched and rebuilt a set of Bosch 3 injectors to replace the crap factory Siemens Deka injectors in the Jeep. Thursday afternoon I did the swap, cleaned out the throttle body since you have to remove it to get the fuel rails off so I figured I might as well. Forgot that I needed a new throttle body gasket, but CanTire had to order it in for Friday morning. Ordered the gasket, buttoned everything back up except the TB and covered the holes on the intake manifold.
Friday afternoon I get off work, grab the gasket, and reinstall the throttle body/cables/electronics. Reconnected the battery.
Went to start it up, ran rough for about 2.5 seconds (~200RPM, figured that was due to air in the fuel rails as I bled the system before pulling them), and then made a weird (but not overly loud) klankety-klunk noise and died. Hit the starter again, now it won't even turn the engine over. Great.
Pulled the steering skid and put a big breaker bar on the crank, and I can't even get it to move a millimeter in either direction with the spark plugs pulled for zero compression and the accessory belt removed.
So I'm kinda baffled as to what the hell happened. If it dropped a valve or something, I can't see how it would lock the reciprocating assembly so hard that a good 200ft-lb on a breaker bar couldn't turn it. Pulled a valve cover and didn't see any missing valves, ran out of light/motivation before I could pull the other. My only surviving theory is that the timing chain broke and bound up in the housing something fierce. Going to pull the front of the engine apart today and see what I can find.
Damnit.
