Welcome to the forum!

What is the 8th character of the VIN in the windshield?

The first thing I would check is the fuel pressure. This is especially true if you can dribble some fuel down into the throttle body and get it to start.

W is the 8th char.

dribbled some fuel down and still nothing

Thank you both for your help and suggestions

Do you have good blue, not orange, spark at every spark plug?

good blue, not orange, spark
 

Spark may be a bit weak....Bought some QuickStart...tried a couple sprays...still nothing... switched the relay from the AC...more QuickStart and LOW and BEHOLD it is running???
Thank you for your help

As Kyle mentioned, you might want to check fuel pressure and leakdown. Key ON, engine OFF, fuel pump running: Pressure must be 60psi to 66psi and must remain above 50psi for 10 minutes after the pump shuts off.
