The distributor needs to be timed... You cannot just add a distributor to an engine.... it needs to be in the EXACT spot to work.....The points and rotor inside need to be in excellent condition also.... You need a mechanic with diagnostic tools.

Ok that's pretty simple Put cylinder # 1 on TDC= top dead center on the (compressionstroke piston all the way up). Mark on metal part of distributor (with marker) where the number one is on the cap( that's where the number 1 wire plugs in) Then in-plant distributor make sure that rotor point is pointed to #1 on the cap, turn distributor shaft until this is achieved or as close as possible try to center shaft so you can adjust... ****** or advance to fine tune after you in-plant distributor if needed. Contact if you need more help . Good Luck

SOURCE: Installed new distributor in 97 Chevy Vortec V6

Check the wire harness to the Ignition control module (ICM) or replace it. It cost around $40,00 from Auto Zone and it's common for the ICM to fail, or it may just be starting to fail and it's also know that the OEM distributor had a screen vent at the bottom of the distributor for ventilation to prevent condensation from forming in the distributor. Check to make sure your new distributor has a vent and that it's not plugged up with shipping plastic. Condensation may be forming causing the misfire in the distributor. Good luck and keep me posted.

SOURCE: 1997 Chevy K1500 Z71 Chevy fuel injector problem

Did you check fuel pressure to make sure you are getting proper fuel pressure? If it will start with starting fluid then it has to be either fuel related or electrical. Are you getting power to your fuel relay? When you turn the key on can you hear your fuel pump come on? I would not use anymore starting fluid at all to try and start it other wise you cause major problems.

misfires can be caused by faulty ignition components, but they can also stem from other components. Such as faulty injectors, or improperly timed or unseated valves. Sounds like you have touched on all of your ignition suspects.
Are there any codes present other than P0304, P0305 and P0306? If so they should help guide you in the right direction. If not, You might want to make sure your valves are seating and if so, go ahead and swap an injector from a misfiring hole with a good one from a hole with no misfire. (like switch #2 and #4 injectors for example) if the misfire moves to cyl 2, you know the injector is at fault.

Distributor in my Chevy 5.7 vortex will not go in all the way its a 2500

If you look at the shaft where the gear is you may see a pin or notch. This is what drives the oil pump rod in the block.
The distributor shaft and the oil pump drive have to match up.
