I am getting agravated with this car not wanting to start and it is getting worse I think. When running it feels strong but at first when trying to start it feels like only half the injectors are spitting out fuel.
I have injectors being cleaned right now and when they come back then I shall see.
trying not to do compression test. I need to sell this thing soon and cant if the motor is shot.
doesnt feel shot, just feels like there is a fuel problem. like too much. I have a fuel switch on it now. sometimes it works.

So - you're in denial..
Afraid a compression test will give bad news?
As long as the injectors are out, pull the fuel pump disconnect & crank the engine.
Listen very carefully to the starter gear noise.
It should be absolutely even across all compression surges is sets of 6.
R_R_R_R_R_R_R_R_R_R_R_R_ = normal
R_r_R_r_R_r_R_r_R_r_R_r_R_ = one rotor is weak
R_R_R_r_R_r_R_R_R_r_R_r_ = a bad apex seal

You are much to quick to advise someone of a blown engine. That shouldbe the last diagnosis, not the first.
A bad primary injector(or connection) will feel like the car running on only one rotor, and sound very similar as well. Dirty injectors will make the car hard to start, not want to run smooth at low load, and gas mileage drops.

car used to start just fine but idle to 3000 rpm. got the idle set and the tps but I installed a fuel cut switch.
since having the cut switch the car will crank and sputter momentarily then acts like the other injectors kick in and the motor runs fine.
once running the car runs fine and idles fine and strong.
I have clean injectors to put in it now tommorrow.
car is for sale now cause I got a 300ZX now.
