<VV> Engine start troubleshooting help

[rod murray]

Thx for responses so far...I believe the problem is electrical....pump
appears to be working as  a) I can hear it, and b) gas is visibly jetting
into the carbs when I move the throttle...thinking coil is next stop since
I saw no spark when I pulled the center distributor wire (from coil).
 Should i be trying a plug wire instead?  I do have another coil I could
put on to try, but figure I should test for power first.    What's best way
to test power at the coil and backtrack from there?

Btw, Power to replacement pump is same as previous setup and had no issues
- have to admit idont recall the source of power for the pump - i just
re-used the same wire as before (pump is a full-time op, i removed the
mechanical pump long ago).  pump is located in front frame rail area behind
tank where fuel line exits tank - hot wire is a light- colored wire pulled
from inside the covered underside center that runs front to back.

Hoping to get this resolved today...

Thx again...

Rod

Hold it close to the terminal and see if it sparks. If not, Check for power
at the + of the coil.

correct between the control unit and the “ring” on the distributor cam
shaft. If all is good but still no spark, change out to points. I returned
MANY defective Pertronix electronic ignition systems.
