starter fluid will burn just off of compression alone.
you don't need spark to ignite starter fluid.

no fuel and no spark.
bad CAS
bad CAS plug
no power to ECU
bad ECU

that's pretty much it.

Soooooooo, after messing with it i finally got it to start(It'll die out if i let go of the gas but that's due to the timing being off from pulling the dist out so many times). Seems like one of the relays that sits behind the ecu is at fault. I don't know exactly which one is it. Eccs? egi? idk(one of the two behind the ecu) Here's the detail, (First of all, i hate dealing with wiring so hang with me.lol). After pulling the dist out a couple times and putting my multimeter to work i realized the camshaft sensor on the distributor wasn't getting enough voltage to function properly. I went back to the relay and noticed what wire was sending the same amount of voltage as what i was getting at the distributor. After jumping it with one that was giving me 12v it finally cranked. However im kind of confused as to the power it gets and doesn't get when the relay is on and when the key is on the on position. Here's drawing i made.........................




What is this telling me? is there a short somewhere?

Ok, so i was out of town basically the entire month of december and had more important things to worry about than this car. Anyways,

The car now starts but it idles like crap. I told you guys i have my fuel pump hardwired. If i have the switch on it will run super rich and idle super bad(im assuming due to it running rich) but i can rev my engine up. If i have the switch off it will idle better but i can't rev up my engine unless i gradually step on the pedal. If i step on the pedal fast it will die out(im assuming fuel starvation). What does it sound like to you guys?


I also pulled out the fuel rail and had someone crank the car, i noticed all 4 injectors fired at the same time. After some research i read that its normal for the injectors to fire at the same time. Is this true?

Sorry I was wrong about that, all 4 injectors will fire during startup. Did you ever change your ecu?
