if you got fuel in your oil, you need to check orings on injectors. Might as well, buy thee entire kit to replace all the orings.

Going on a limb here, but if oring/s are bad, then i can see how the lpop cant create pressure..(low oil pressure), with a shot oring, or the lpop itself is just bad too. Melling 208 is what they replace them with....but fuel in oil, you need to find the culprit.

Do I need any special tools to remove injectors and is there a way to tell which one may be bad before I pull them

if the truck is running and your oil pressure gauge is not registering, the gauge is inaccurate. either due to the sender, gauge, or wiring.
check your codes and report back

Yes I figured the gauge is ring because if there was truly no oil pressure then the truck would. Not run but still runs very rough but no blue or white smoke
