Ignition, no spark at all. not to the spark plugs or distributor.
I replaced the coil pick up and coil, gap the the ciol pick up to specifications. .31 and still no spark, what`s really frustrading is that it was working fine. there appears to have voltage at the coil pick up, about 10.50 v to 11.00v . and to the coil it self about 5.5 to 6 volts. the ballast resistor has the proper resistance. 1.2 ohms .
so what could be wrong?...............................

Sounds like you have a bad distributor. Most of the time there is a magnetic sensor that breaks inside of the distributor, but it will cost just as much to go ahead and replace the whole distributor. make sure you mark where the old one was before you remove it and line the new one up. That should get you going.

Hi,have you tryed testing the coil,to see if it has a spark,you should check sparkplug,then h,t,leads and distibuter cap,then the l,t,lead that runs from coil to distributor, and rotor,then,check the distributors getting power then ciol,then power to the coil,hope this was some help,all the best.
I guess you could have the ignition analyzed on an oscilloscope. Maybe a tech could see something then. I always heard the only gap was the spark plug gap-the rotor has no gap-are you sure you got the correct rotor? And does it touch the top distributor cap coil wire tower?
Let us know. It is a mystery worthy of a solution.
1) The primary circuit: is battery, cap, resistor, capacitor,switch ignition+secondary circuit spark plug, distributor, high tension wires+spark plug. the mayor problem arise in the coil and distributor, And the most common problem INCORRECT Choice de spark plugs or improperly gapped. Rememeber the coil send 20,000-30,000 Vdc for spark plug. Test with a screwdriver , pull out the center wire from the distributor cap and hold 3/8inch from a good ground. Crack the engine, if there no spark, or the spark is weak, the coil is defective or the high tension wires. 2) Bypass by a moment the baas resistor with a jumper wire while cranking engine If the engine starts, replace the ballast resistor.
Test the ignition system output, ignition systems can vary in configuration but operate on the same principal. Ignition systems can consist of a coil, pick up coil, crank angle sensor, cam angle sensor, spark plugs, spark plug wires, distributor cap, ignition rotor and a distributor and any variations of these components. An ignition coil is a voltage stepper coil that transforms a low voltage (12 volts) signal into tens of thousands of volts needed to jump the gap of the spark plug.
This coil is activated by an ignition module triggered by using the camshaft/crankshaft angle sensor; timing is adjusted by the PCM (computer).This primary electrical signal is generated by the PCM which calculates spark timing by using a variety of sensors including coolant temperature, mass air flow, and oxygen sensors. Go to 2carpros.com for a video on how to check this using a 12v light tool. On the engine repair section search, type, "engine cranks but will not start." If my answer helpe you, please leve good feedback. thanks
There's no emergence switch, if there was it would only be for fuel and not spark, there four thing to get spark, ignition control module, ignition coil, distributor pick up assembly and spark plug wire's check for spark at coil, more then likely it's going to be your distributor pick up assembly, the pick up sit in side your ignition distributor, replace it and it will start, hope this was very helpful.
Since the distributor is in the front on the 460 and you replaced the water pump check the connection plug coming from the distributor. If you disconnected it when removing the water pump you may not have made the connection tight enough to complete the connection. Look for pinched wires also. And your engine does not have points. You have a breakerless ignition system in the distributor. The air gap should be set at 8 thousands of an inch. Check the gap. Good luck.
