all of the injectors on the passenger side don't work all of a sudden?

My car runs like a piece of cr_P. All of the injectors seemed to of went out at the same time. I recently put on a new IAC,TPS and SLP runners. any ideas of what it is and how to fix it. there is no way all four can go out at the same time. I pulled off top clip part to check it when it was running at it confimed that all of the ones on the pass side are not working. I heard someone say somethng about a fuse in the computer fot TPI's that regulate all four on each side with a different fuse for each four injectors. if that is the case how do I fix that if the fuse is in the computer?

Its not in the computer.
If any injectors fire, the driver in the ECM is working. You must find the supply fuse for each side and replace the blown one.
IDK the location but someone will chime in if you can't find it.
