Ok this is an on going problem
Upgrade to an HEI ignition in 2010, when it works,works great.
Have had ongoing issues with spark, have put several new coils in, than it works, for awhile.
HAve had to replace the module, tested bad,2 times,replaced, than it works.

Once again replaced the module,old one tested bad again. But now I only have intermitent spark when trying to start.

Any ideas on what can continue to cause these issues?
Turn on ignition we have 12v to ditributor, checked my grounds they are good and working, ohm my pickup in the ditributor no broken signal,
what would cause coils modules to fail?
thanks for the input.

Multiple coil failure can be from several things, but usually spikes in the voltage can cause that, or intermittent loss of ground. I'd check the resistance of the wires, and jiggle them when doing so to make sure you don't have any wires that are shot / corroded inside.
