New battery & starter. Have lights horn radio

Assuming the engine has not siezed, there is a short in the starter circuit. Probably the starter/solenoid, but you can verify. Disconnect the negative battery terminal, then the big red wire from the starter solenoid. Wrap the wire terminal tom prevent shorting, reconnect the battery terminal and try again. If nothing happens this time, replace the starter/solenoid. If short is still present with starter unhooked, trace wire back from starter to find short. Let me know if you have more questions.

1994 silverado 4L60E transmission not wanting to shift corrrect

If you have not worked on a 4L50E transmission before, leave it to someone who is familiar with the the 4L60E. The solenoid is in the valve body and i know some who have put things back together and needed to take it apart again over something simple as a servo pin in revers. Best thing to do is get the truck scanned at Auto Zone free of charge or at a transmission shop with a tech 2 scanner for DTC codes. If there is a bad throttle body sensor or it's misaligned, it would affect your transmission's performance. The throttle body sensor send's signals to the ECM which calculates the amount of transmission fluid pressure though out the shift points, if that signal is bad then your shift points and firmness will be affected. There is also a cheap and great performance upgrade for around $50.00. You have a Transmission shop swap out the servo's for a Corvette servo's, it can be done in 30 min with out taking the transmission down or removing the transmission oil pan off.
Recap, have the transmission fluid and oil changed and have the throttle body sensor tested. It should show a smooth gradual increase in resistance with out any fluctuation. You truck is 15 years old and it may have a dead spot on the sensor now and it may need to be replaced. Good luck and keep me posted, Be glad to help and you can also have the transmission shop do a transmission pressure line test.

I have a 1994 1500

Before you go tearing up the transmission. Check tp sensor (throttle position sensor). Keep in mind transmissions also have electronic parts that govern shift patterns . Signals sent to the truck's computer from sensors govern when it shifts. I would check sensors and wiring to those sensors first before tinkering with a transmission.

Have a 94' chevy pickup.

Flush the system and look for contaminants. If there is a bleed on the proportioning valve, also flush there. If there are contaminants, your master may need to be replaced. If not, maybe the proportioning valve has failed again.

My 94 Chevy c1500 v6 pickup truck is having issues

The only thing I know of, on a gasoline engine, that will bite you is secondary ignition voltage. What about your ignition coil? If the vehicle will run, raise the hood in the dark, look for fire/spark jumping around.

Can u tell me if cylenders on a 1980 chevy 350 5.7

You have the numbers right but the actual firing order is 18436572 likely why they are in what appears to be a "different order" That order is how the wires are connected at the cap. # 8 will be the one after #1 in the direction the rotor turns etc.

94 chevy C1500 and about five blocks after I start it and come to a stop sign it trys to cut out and die, if I put it in neutral and red line it a couple of times it runs fine the rest of the day

Black smoke when you red line it? this would be a leaking injector. Loading the engine with fuel.

How do I get the truck to start now? Could I have shorted something out by messing with blend door actuator?

If it starts and runs when you add gas manually then you have a fuel delivery problem. Check the fuel pump relay and check the fuel pressure if the relay is fine. You might also have someone turn the key in a quiet environment while you have your ear close to the gas tank area and see if you hear the fuel pump run.
