ignition problems
I have a 1994 Silverado with a 4.3L
Was having rough idle problem which led to shutdown while driving. Now it will not start. My fuel pump, cap, roter, are all new. It has good plugs and wires. I'm at a loss for where to go from here, please help.

With all the info all I can suggest is to replace the cheapest part first.
You're going to have to determine of it's a fuel or ignition problem first.
Pull a plug wire off the spark plug and hold it 1/4 from the exhaust manifold and have someone crank the engine over and see if you can see the spark jump from the wire to the manifold.
You really should use a fuel pressure gauge to determine if you have fuel pressure or not. You can usually rent them from a auto parts store.
