No oil pressure!!! Please help!!!
No oil pressure!!! Please help!!! Well I finally installed the motor I have in the sig. It sat for about 8 months with no oil pan, or timing cover but had a bag over it so it didnt get dirty. Well after the install, I fired it up and saw 0 oil pressure 
Well I looked all over the site and figured it was the o-ring to the pick up tube. Well I got it out and it was a little squared off but not torn or anything. Well I replaced it anyway and re-installed the oil pump. I then bolted up the pan and filled it with oil. I un hooked the coil packs and tried turning over the motor to build pressure. Still 0 pressure. 0 on the pressure gauge. There is 0 oil getting to the top of the motor Then we opened up the oil pump and found the new, fresh oil we just put in it???Is the pump just barely working enough to get into the pump itself but not enough to get to the top of the motor? Am I overlooking something? Did I do something wrong with what I did? On a side note, the oil pump is a low mileage ported pump that came with the motor I bought. It had no issues before but I guess it could have went bad from sitting???
Please help guys! I am lost

Is the oil pump new? If its not too hard, take the allan bolt out of the bottom where the spring is and make sure the little valve in there still moves, thats the part that siezes up and makes these things quit working.

Did you install the oil galley plug behind the rear cover? Did you make sure the oil galley freeze plug was still in place behind the front cover? If it was a used block, the freeze plug should be there, unless it was removed at the machine shop,etc.

I would think that the computer must be seeing some oil pressure, because Im pretty sure they have a low oil pressure ignition kill. I could be wrong on that one though, it may also be timed.

Well the motor is not redone from a machine shop so I dont know how the oil plugs could have came out of the front or rear of the block??? It is also not a 98 motor. It is a stock short block out of a 99SS, with ported pump, dbl. roller chain, GTP stg 2 heads, Yella Terra's, 228/224 cam,LSX, etc. The motor was pulled and I took it home where it sat for at least 8 months. Can sitting make a oil pump go bad? I am going to try a used stock pump and see if that works, and take apart the used one to see if it is stuck.
