1998 sunfire in codep1629, how do I fix it

You may want to do some research on the code. The basic problem is the anti-theft system is not seeing a crank signal and shutting down the fuel pump. It could be the security system, or the crank sensor, or other issues.
If you have auto start or a remote starting system it can cause these problems too.

Replaced the starter, the ignition switch, and the relay on the starter and know my 1999 Pontaic Sunfire will not start. I have a theft system but it don't work do I need to reset that?

Changing the ignition has caused a break in the communication of the anti theft security system. Here is a link that will explain how this system works and offer some ways to fix it yourself. I've been dealing with these systems for a long time, i've had great luck with just bypassing the entire system. there is a link for that also on this page.

I have a 1999 pontiac sunfire with a remote start. Sometimes when I push the remote to start my car, it will start and shut off right away and the anti theft light will flash. Is there something that I can...

no but what you have bad is your remote start brain box that is triggering the anti theft. i suggest taking to a auto electronic place for servicing or stop using remote start.

My 00 pontiac grand prix starts 3 seconds and shuts down

P1122 is a throttle position sensor code. P1629 is a theft deterrent system code. P1122 will set when the voltage signal from the throttle position sensor drops below 0.1 volts. Normally, the sensor should measure between 1 volt at idle and 4 volts at full throttle. A failed throttle position sensor could easily cause your problem.

As for the theft deterrent system code, with that code set, the car shouldn't start at all (if the code is active). With P1629, the engine computer should refuse to deliver fuel to the engine. This code can be stored for up to 40 warm up cycles before clearing itself, so unless it is currently active, there may not be any need to worry about it.

I would inspect the wiring and connectors leading to the throttle position sensor. If that wiring is good, I would replace the sensor and see where that got me. Give that a try and let us know how things go.
