Not reading any oil pressure at start up after hibernation. HELP

The Story:

Last October my clutch went bad so I just put it down for the winter. Well, over the last couple weeks I started out by changing the oil pan gasket. I got a new one on but I couldn't drop the pan out so I had to snake one in. It seemed to go in ok. Then came the clutch along with a new rear main seal and pilot bushing. I also had my pcm done by pcmforless. Since I couldnt drop my pan I bought 4 qts of regular oil and ran 1 through with an open drain plug, then filled it up with 3 qts and drained that hoping it would flush anything little that might have gotten in there. I got all the good fluids in there and went to fire it up today and right away I noticed I wasn't reading any oil pressure so I shut it right down. I tried again and the same thing. I havn't checked all the fuses yet but what else could it be? Something with the tune? I'm at a loss with this one and i'm not sure where to start looking. I'm afraid to try and start it again now. I really dont want to fry my motor. Please give me something to look for!!!

Did the oil pressure gauge work before the clutch went out? Just wondering if the gauge is the problem? I'd try checking oil pressure with a known good gauge.

Did you change the filter with the new oil?

Did you check the oil pressure sending unit connector and see if it might be loose or broken. It is behind the motor on the drivers side.

^ Yeah, the sensor was broken so i'm pretty sure thats it. I just cant get the damn thing out. Talk about no room to work. I wish I would have caught it when the bellhousing was off. What a way to **** a guy off.
