No Oil Pressure on Start Up
Sounds like you are having more problems than just oil pressure if your engine is shutting off on you.
The TSP pump is working like a champ; my oil pressure is 60 psi hot @ idle and about 75 psi cold. That is through the factory gauge though, my Auto Meter gauge crapped on me. It is reading pressure, but the needle is at the bottom of the gauge not on the labeled/numbered area of the gauge.
Of course I would do things the hard way, I pulled every injector plug rather than pulling the fuse to the pump.

I am having this same problem. My motor runs for about 3 seconds or so then dies. The motor has been sitting for about a year and a half. I have started it for 3 seconds a lot though like 10 times to check different things I thought were the problem. I am now afraid to try and turn it over. Should I try over filling it with oil like the one guy suggested. Where is the plug he is talking about too? Please help.

Before you tear down your engine and check the o ring, I suggest you overfill the crank with cheap 5w30 oil. Before doing so pull the plug on the driver side lower front which is just past the oil pump. It took 19 qts for mine to flow out this hole but I have a modied pan and it only holds 5.5 qts when full. I pulled my engine out 3 times, installed 3 new oil rings, double bolted the pickup tube, added rtv and still no pressure. Turns out the problem was the pump was dry and would not prime it self. Once I got oil in the pump it has worked every sense. There are other ways to prime it but I think you need a special kit. Turn the engine over without starting it. Once you see pressure drain out the oil and fill it to normal level and start the engine. It worked for me, might save you time and a headache pulling the engine and dropping the pan.
