Firing order for 93 silverado 5.0L for sparks and disturbor

Firing order is clock wise rotation. You can see firing order in picture. You can see how cylinders are numbered. I did show number one terminal on distributor cap, according to my database. I don't like to do that because I've seen many pictures that were wrong. If you put number one piston on tdc of compression stroke, which ever spark plug tower the rotor is leading into is number one, then follow firing order around cap in direction of rotation. Just my opinion.
I looked at 93 chevy pickup, 350 engine.

I would order a Chilton manual for your truck. eBay is a good place to get one ($25).

Firing order is 1-2-3-4-5-6 , engine numbering is 1-3-5 towards the back and up front is 2-4-6, coil numbering from left to right is 1-4, 6-3, 2-5. This is for your year of engine I hope this helps you!

If your timing marks are on ... there is spark and fuel you may just have the firing order off ... When checking the firing order be mindful of the rotation of the engine.

I would try making sure spark plug wires are put on in the correct firing order. This is a common mistake in tune ups. Most intake manifolds have the firinging order cast in. Plug gaps correct? I cant come too far away.

The firing order and spark plug wiring layout is depicted in over-the-counter repair manuals like the Haynes for '87-93 Ford Mustangs. If you can't spend the ~$20 on one of those (available at Pep Boys, Autozone, eBay, Amazon, etc) you should be able to check one out from your local library.
