Thanks I checked the guide and still no solution. All the lights are on the dash so it’s not the EFI relay.

What things did you do to troubleshoot, as in step by step ? We want to be efficient and you need to tell us
That guide is huge so start putting forth some effort.

Crank and no start is one of two things. No fuel or no spark. Pull a spark plug and see if you get spark. If you are then its a fuel issue. If not its a spark issue and track back accordingly. Can really resolve till you find the issue

Lemme give you some backstory the vehicle was running fine. I had some intermittent issues with a cheap Walmart 650 cca battery. Every once in a while it would click and start on the second try. I attributed this to a crappy battery and terminal corrosion. Recently I started it up it was running for 5 minutes and it shut off wouldn’t start again. Put in a new battery and still not running. The vehicle was previously wired up with an audiovox alarm plus the stock alarm and a fm/am modulator. So the wiring under the dash is not the cleanest. I am working on it in a parking lot singlehanded so it’s not that simple to diagnose. Can a bad alternator make an 80 series not run? From what I understand obviously it would still run and just die out when the charge went on the battery.

My advise from above is still your best start. If you do not have the tools to pull one spark plug wire off and look for spark then you are most likely going to need to get it towed to a shop.
If your truck cranks over its not the battery or alt. You are either not getting fuel for the spark to ignite or your not getting spark to ignite the fuel. Find out which one of theses is you problem then you can start tracing back to why your not getting one or the other.
Otherwise just sit there and blindly change out parts with no idea what problem your trying to fix.
Could an alarm be the issue??? yes but who knows.
Your also describing two different issues. In one case you said it would crank and no start. In another you said it would not crank and then would.
Not crank and then would can be battery [sprark} or starter but that is different than crank and no start.

Give all the backstory you want. Nothing wrong with that. I assume you got peved at the statement about pulling a spark plug or towing it two a shop. Still same advise. If you don't have the ability to see if you have spark in your current situation you don't have much chance of solving it. Just my opinion, but then im not the one looking for advise.
You too have a good day.

There is a very detailed table for troubleshooting in the FSM as well if you’re looking for a more complex list of things to rule out.
But @REKCUT has linked up the best place to start above and it’s written out in easy to follow terms. There are a lot of “no start threads” on the forum where folks tend to repost the same tried and true advice, which is pretty tiresome to wade through when you are searching for answers (if your rig is not starting then you have probably already discovered this).
