I changed the plugs and wires and distributed cap and rotor button it starts up good.but will not thortle up

check that wires are correct -rotor actually making contact with cap

I would think a dist. cap and a rotor button. By what you describe, the fire is getting to the distributor but not going to the plug wires.

is it getting gass if u got spark to the plug's it should start.dump alittle gas down carb or throttle body making sure to replace air cleaner or snorkle and try and start.if starts could be fuel pump.

If the wires are still in the distributer, AND, if you have a stock intake manifold, the firing order is on the manifold. If it's a V-8, the number 1, 3, 5, & 7 plugs are on the drivers side of the engine. The number 2, 4, 6, & 8 plugs are on the passenger side. The number 1 plug wire can be located by looking at the distributer from the front of the engine and visually looking between the distributer and the number 1 plug. Visualize the distributer as a clock. The number one position should be located between 4 and 5 o'clock and should have the longest wire of those on that side of the distributer.

If the wires have been pulled from the distributer, then, then, remove the rotor cap, turn the engine over slowly until the rotor is pointing to the number 1 plug. Using the firing order on the intake manifold, starting with number 1, replace the wires going clockwise around the distributer.

I would definitely try the distributer cap and rotor button. It's about a 15 minute job and might solve your problem. As the car warms up the electrical components of course heat up too. As the heat goes up, resistance also increases in electrical connections, wires, etc. You could be getting enough current to pass between the rotor and the poles at low temps but, as they heat up, sufficient current for a good spark is not being passed along.

change the pick up coil inside the distributer under the rotor button.

Take the screws out of distributer cap, mark exactly where the rotor is pointing with paint pen on distributer cap and distributer. Loosen bolts holding down distributer. Lift out distributer after you unplug electrical wires. Place new distributer in place making sure rotor is pointing to exact same place where the old one pointed. Replace distributer cap and electrical wires and your done, try to start the car.If car starts your ok.If it doesnt start andd backfires it means rotor is in wrong place,take back out and restab it.good luck

it does not mean new parts are alway good. subtitive a known good wire and check for spark at the wire, if there is spark then check the plug.
if there is no spark then go back to your cap.

First thing is to ck for a spark, see if she has good spark. Next remove the cap and watch the rotor button as it turns, have someone crank the engine to see, looking for which direction. Next turn the engine by hand looking for any marks on the crankshaft pully. aligning any marks should be #1 or #4 piston firing position. you will have to do this trial and error. Next if your rotor buton turns to the left align the marks on your pully and put your # 1 plug wire at the port in the cap which the rotor button is pointing at, then next put the #3 plug wire in,next #4 and last in turn would be #2. The firing order is 1,3,4,2.which ever direction the rotor button turns. if it starts and runs ruff you are out of phase 180 degs. move the wires two ports in the cap as the rotor turns. 

You may think that the distributer cap looks good.Its very hard to see if its cracked with the human eye.So i would change the cap.Then see where you go from there.Let me know.pippall.Good luck.
