No fire from the cap

I replaced the cap, rotor, coil, pickup in the dist.,wires, and plugs. Still no fire, any info will help.  

Check the ballast resistor. When these go bad the vehicle will not start. Bill  

did you by chance change the air gap of the magnetic pickup in the distributor.  if it is to far apart it will cause high primary resistance and can cause the secondary side of the ignition system not to fire  

I second the ballast resistor comment. Disconnect the wires from it and use a ohmmeter to see what the resistance is. If there's no continuity at all, it's bad. there are a few different ones. 1/4 ohm, 1 ohm and so on. If you get no resistance, that's your culprit.

Reluctor...  

got a digital volt meter....   set it to 2K ohms....  measure the pick up coil... at the distributer connector... 500 to 1,500 ohms is good...      

without disconnecting ...   flip the digital volt meter to 20 Volt AC scale.  spin the distributer shaft.. or crank the motor...

with the distributer out.. you should get over one volt..AC....   with the distributer in... not quite a volt.. but close..

why... the reluctor as it spins... holds a little magnetic field...  this rotating magnetic field passing through the pick up coil creates a nice sine wave...   the voltage has to go high enough to turn on the transistor in the module... if it does not reach that level... it will not turn it on...  if it cannot turn it on... it cannot turn it off to fire the coil... NO SPARK...


((( rusty reluctors and sand blasted reluctors loose their abilitys to maintain a magnetic field..)))


you should also test the wiring for resistance at the module plug...  with the distributer plugged in.. and then again with the distributer spinning..


you can also test the ignition.. by spinning the distributer shaft with the key on...    the coil should spark... i like to be sure to touch the housing to ground... just in case... other brands require this... for the ignition to work...  or the spinner may get a nice high voltage shock..


be sure to look at the inside of the reluctor... there are two slots for the alignment pin... look closely ... one has a tiny arrow... if the arrow is pointing in the normal direction of rotation.. put the pin on that side...   if the arrow points in the other direction... put it in the other slot...    putting it in the wrong slot will cause the rotor to be slightly out of phase with the cap terminals....   look at the cap terminals ... is all the arcing to one side of the cap terminals.. then its in the wrong place...

i have also found that some rotors are too short...  so the jump from the tip of the rotor goes straight up, instead of out the tip...   for some reason this makes for a weird running motor...


one can see in this image that the notches for the roll pin are not even.. but the arrow for the direction is on the other side...

hope this helps...
