I assume you don't have a service manual for an LT-1 Camaro/Firebird. Do a google search and download a service manual for the year of the engine. Then follow the troubleshooting chart available in the manual.
Edited to add: See example from 96 Service manual:

Cranks but doesn't turn over. Ran fine a month ago. I don't have a service manual.
Does have an ODB1 port but I don't have a tool to scan.[This message has been edited by str8maxn (edited 05-14-2024).]

Get the service manual. It's invaluable.
Since it does not start, there are trouble codes present. The manual may tell you how to read the trouble codes without a scantool. Get a cheap code reader for OBD-I and save yourself the trouble of troubleshooting in the dark.

Got a Haynes Repair Manual, But can't seem to find any good troubleshooting procedures for Crank No Start.
FYI- I have verified..
Fuel Pressure
Spark at multiple plugs
Spark at the main ignition plug
Signal to multiple injectors
Any suggesting for a better repair manual?
Thanks

Have you tried spraying starting fluid into the intake when cranking?
That will verify spark, if it starts.
If it doesn't start, you have no spark.

**** !! Typed an entire post and it got deleted before I could send. Anyway....
Get the FACTORY SERVICE MANUAL. There is an PDF version for 50 bucks. 200 bucks fir printed...YIKES! You'll have to search your year On the Motor Bookstore site. I just used 1997 as an example. In my experience Haynes and others are total crap for more advanced troubleshooting.
And yes. You will need a scanner. Unless you are an engine whisperer.

The 1997 factory service manual will be of no help to you because it's for OBD-II.
Search for the factory manual for the year of your engine.

Yes. In my post I said this is an example to get him a source for a manual. He'll have to search for his year. No idea what year of engine through this thread.
