No injection, removed command start, well not start on key?

Hello all !
Marty here !

So these Aveo seem to be the things bad dreams are made of! Lol
Any way, I have a 2004 Aveo 5 and have spent a good week trouble shooting it.
And tured out to be the computer star auto start but I only got that figured out on a chance that it deside to start working again! But the car would only run if I Press the little button on the back of the computer computer box an Press the little reset button on the back of the computer computer box box d then turn the key, so I took all the wiring to this auto start out of the car and now it will turn over but no injection!

Is is there something that would need to be replaced after all that wiring I removed that would send the message to the injectors from the key switch ?

I have changed and test all sensors but really sure it is an under the dash problem now and for some redone the compu star would send the message to inject but the key alone will not !

Any my help would be awesome? I'm close to TnT lol !

Thank. Marty

this is an aftermarket remote start? is sounds like you might have disable the immobilizer in the process?
