89 RS Camaro 358 starting issues
89 RS 358. I just recently replaced the fuel pump, fuel filter, cap, rotor, plugs, wires. When I done the timing, I unplugged the ECS (think thats whats its called) and then put it at 0*, done my firing order correctly, plugged the ESC back in and now In order for it to crank up, I have to spray a little starting fluid into the TBI. It'll run a few seconds then die. I replaced the coil and I still have to spray starting fluid into it to start it. Can someone please help me out.

Starting fluid doesn't substitute for the coil.
You just wasted your money, buying that.
Starting fluid replaces FUEL. If the car won't start, but then starts up when supplied with an alternative source of FUEL, then the Magic Ingredient (of which there are 3: compression, air/fuel, spark) that's missing, is FUEL, not "coil".
You have a FUEL problem. Work on the FUEL system. Find out why FUEL isn't making it into the intake manifold. Never lose sight of the unfortunate fact that "new" doesn't automatically mean "working"... observing the actual performance and behavior is more important than "new". You may be the victim of having just installed a defective fuel pump for example.
Try simple stuff first, like taking off the fuel lines and pointing them into a container and turning the key on and seeing if fuel comes out. You might have done something simple like unplugged the fuel pump relay accidentally, or not got the fuel pump connector all the way plugged together good and not noticed it and it just fell apart. The ECM might just be mad about VATS or something stupid like that. In any case, find out why the fuel system is disabled. Start by looking at anything that you touched... another unfortunate fact of working on cars, which is, that if you just worked on something and now it's broke, you need to go back and check your work.
You'll likely also find that your motor will run AWHOLEHELLUVALOT better at some "timing" setting other than "spec" from "book", based on some sheet-metal configuration. But worry about all that later; leave it alone for now, because it isn't the thing keeping the car from running; focus on fuel for the time being.
A little further history might also help; such as, has this motor ever run in this car before? Why were you changing out all that stuff to begin with? (boredom, wallet too heavy, car had failed, ???) Things like that. We can help you better if you point us in the right direction.

Fuels getting to the throttle body and does the little spurt of fuel to start the car, but doesn't seem like it's enough to start the car, after the engine fires up, fuel sprays from the injectors.
I replaced the fuel pump cuz it went out and anytime I replace fuel pump I go ahead and do the filter. I did take off the line and turn the key and test the fuel pump and its pumping. The wires and all was just a tune up. Yea the engine ran in this car. I did go back and recheck everything making sure everything was connected properly and sealed up good

It fuel is present, but isn't enough to actually supply a running engine even at idle, then you may just have installed a defective fuel pump... it may "pump", but just be unable to deliver adequate volume/pressure for the system to work properly. Which would be a bummer. Needless to say if there's not enough fuel getting moved for the motor to even idle, it's sure gonna have alotta trouble with driving, when it will be needing a many times greater amount. Unfortunately with TBI it's tough to test because there's not a fuel pressure test port.
I used to have a Cheep (Bland Cherokee)... FP went out so I changed it. NBD I thought. Yeah right. First one I got, the engine was very hard to start, and would idle out of gear, just barely, but not in; and couldn't back down the driveway even if I kept giving it the gas pedal. FP turned out to be low 30 something when it should have been mid-high 40s. (port injection, not TBI) Took it back, they gave me a new one. 2nd one, the FP was over 70 sitting idling; the car drove, but it was terrible; took it back out, turned out the fitting the return line plugged onto (plastic) had casting flash blocking it. Drilled it out and put it all back together. After the 3rd R&R it finally ran right again. I hope yours isn't that much of a PITA.
