Got power to everything but doesn't start. I just took the aftermarket alarm off because I thought it was draining but it did start. Bought an immobilizer bypass. Got an ignition key and tumbler and the switch at the other end but haven't put it on yet. I need to start it to take it where I can work on it. So, it's a twofold question. What's wrong and to get it to start?

When you removed the aftermarket alarm did you reconnect the wiring back to stock? Also when you try to start he car does the security light flash? Lets run the codes to see what come up here is a guide to help you please get back to me with the code.

Yes, all wiring was matched back to the original color coded wires. No security lights flashing. When you try to start the lights go dim as if it were starting. Started before I took the alarm off. Last time it started once you put it into gear and tried to take off it seemed the car was trying to kill the electric portion of the car. Thus removing the alarm which is not needed and poorly wired in. The immobilizer icon hasn't showed itself and after re-connecting the wires I don't think there is one one it. Which I was looking for at the time. I need to get it out of where it is which is only 3 blocks from my house. Since I have electric power pushing it and popping the clutch seemed like a viable option. Yes or no?

Yes, that could work, it sounds like you need a battery though, to be sure this guide will help load test the battery with the use of equipment:
