How much cranking
I just got done with my injector cup job i rolled the motor with a breaker bar 360 degrees twice very little oil came out. This trucks been drained of fluids for about a month. I have everything plugged back in bolted up and all. I've been cranking for about 10 minutes off and on giving the starter a break. Also my batteries were about dead so im cranking off a 50 amp jump starter. Is this typical for having to work out all the air?

- does oil pressure gauge come up while cranking?
-Do you have 10+ volts on batts
-is ipr plugged in?
Dead batts and 50 amp charger probably cannot keep up with glow plugs on and starter running. Glow plugs are up to 10 amps a piece or more, starter can use 4.36+ kW

Proper battery voltage (10.5 VDC minimum) is a must as mentioned. Just because the engine turns over is no guarentee that it is enough. If abmient temperature is over ~70* - I think - the glow plugs are not in the picture at all anyway. If it is cold enough they will kill a low battery in no time at all. Also it can take quite a bit of cranking to purge the air out of the system after this kind of work. Just be patient and don't over do it and fry the starter.

Just for reference I just had a motor that sitting with no oil at all and got new injectors running. It took 3 tries of cranking at about 20 seconds each and it started. The first 20 seconds and I did have oil pressure showing on dash.

Well she finally fired off hardly any smoke took it for a test drive and pretty much got scared cause it felt like it was about to sling something. If you punch it it revs up to 2500 rpms but your only doin 30 is this normal. I swear that things was shakin and rockin i couldnt get it back home fast enough

Its also throwing the p1316 code for the uvch. Will it do that until airs worked out or is there something actually wrong with the harness or injectors. It was idling smooth but started getting a rock to it since i drove it.

P1316 means the IDM has stored codes. Run a KOEO or injector buzz test to see what codes the IDM has stored. Do this, then clear them and see what comes back.

Sounds like it has the air bucks, some air depending upon what was removed and installed may still be trapped inside so it will need to be worked out, IIRC can take up to a good hour or better with injectors and cups and that is actual drive time with varied Rpms

I would buy a special uninsulated terminal crimper and repair kit if you don't need to graft additional wire. This would reduce the number of connectors and potential for issues. The connector shell, silicone seals, and terminals will be included in addition to terminal release tool.
