Hello my name is Scott

Ford Mechanic: Scott W., Ford Technician replied 2 years ago
From your description it sounds like you may have a worn oil pump, when you removed the seal the oil drained out and now won't prime. Or the cam sensor wiring or sensor was disconnected or broken. Does the oil pressure come up in the dash while cranking the engine over?

It won't crank over
Ford Mechanic: Scott W., Ford Technician replied 2 years ago
You mean the engine won't turn with a breaker bar on the front crank bolt?
Ask Your Own Ford Question
Customer reply replied 2 years ago
Right --it will not turn
Ford Mechanic: Scott W., Ford Technician replied 2 years ago
What exactly was done during the removal of the seal, was the oil pump pulled out?
Ask Your Own Ford Question
Customer reply replied 2 years ago
Yes the oil pump was pulled out
Ford Mechanic: Scott W., Ford Technician replied 2 years ago
I have never seen this before, did you disassemble it to make sure the oil pump is not binding?

Ford Mechanic: Scott W., Ford Technician replied 2 years ago
Ok just looked at workshop manual, big caution pointing out the inner gerotor gear should only go on one way, I suspect this could be the cause.

Customer reply replied 2 years ago
Will double check now...
but had changed the oil too & it hasn't started enough to prime
Had some1 else say that it may be hydro locked, and to check glow plugs....
Thought originally that it didn't have enough juice to crank b/c it was clicking & starter was hesitating --put boost pack on one battery & it's sound just sped up but still would not actually turn over
For good measure starter has lifetime warranty so swapped w/a new one .....
Ford Mechanic: Scott W., Ford Technician replied 2 years ago
I will give you the oil pump instructions so you can see what I am talking about.

Well checked glow plugs and one was covered n oil... But tested & it works--
When took harmonic balancer off & glow plug out-- can manually turn motor over some now...
Customer reply replied 2 years ago
So far all glow plugs coated in oil
Ford Mechanic: Scott W., Ford Technician replied 2 years ago
Are the pump gears installed correctly, looking for oil on the glow plugs can be difficult because when you remove them, oil runs down the glow plugs.

Ford Mechanic: Scott W., Ford Technician replied 2 years ago
What sleeve ae you talking about?
Ask Your Own Ford Question
Customer reply replied 2 years ago
The one that comes with the seal.
Ford Mechanic: Scott W., Ford Technician replied 2 years ago
do you need any more help or are you all set?
Ask Your Own Ford Question
Customer reply replied 2 years ago
Well I got it going but one quick thing. What would make it slow to start. Like it crank over a little more than normal.
Ford Mechanic: Scott W., Ford Technician replied 2 years ago
Air in the high pressure oil system will make the engine crank over a lot longer because it has to compress the air to build the oil pressure to start. Usually driving 10-15 miles will bleed the air out.
