Won't Start

I have a 1992 S10 Blazer 2wd 4.3l TBI that I bought about a month ago and it won't start. It did start when I first bought it as I drove it home with no problems after about a week the battery went dead and had to jump it. The battery held a charge for awhile then went dead again. I got a new battery and it started. After a couple of days of setting it wouldn't start it would crank good but wouldn't start. So I checked for fuel and I can see fuel getting to the throttle body, I also replaced the plug wires but not the plugs because they were replaced recently, I also checked the cap and rotor and the cap had some corrosion on it but haven't done anything with it. Oh and it has a remote starter installed also but I disabled it with the switch because it was giving me troubles. I am not sure what is wrong but I would like some extra input on this before I just go replacing stuff.

Thanks

When no start check for proper fuel [pressure and injector squirting.
And make sure you are getting good hot blue spark to all plugs.
Let us know what it does not have.

It has good pressure and the injectors are squirting good. It does not have spark. Coil maybe?

On a 92 I would check ign module first.
Check for key on power to coil and dist.
Is dist rotor turning when you crank it.
Check for spark right at coil wire and for spark into dist cap.

Some parts place can run a test on ign module and coil for bad or good.

Ok thanks I will try that and get back to you.
