'02 7.3 Just replaced the hpop, motor won't turn over Hydraulic?

Replaced the high pressure oil pump last night. It sat for about 2 weeks with the old one out while saving up the $700 for pump and valve. When it went out on the freeway the motor turned over fine ( just didn't start), now it won't turn over and acts like the cylinders are full of oil/fuel something. Could the injectors have bled down while it sat without a pump? I am about to take off the valve covers to get to the glow plugs so I can empty the cylinders, but am wondering if this is something that happens or if something else is going on. I'd love t avoid this if possible.

how was the engine acting before you pulled the pump?

If you lost power it may not have been your pump. I lost power and it was just the wires to the glow plugs under the valve covers. they cost about $100 a peice. when they get to hot they expand and then pop off if both came off you would not get anything out of your motor. you can buy new ones or put a couple black z straps around them to hold them in place. Hope this helps.

p.s. I did all the work myself in a couple hours dealer said 6 hours labor.
