Help! My 91 chevy truck is not getting fire at all. I have replaced the
ignition switch, coil, ignition modual,computer, dist cap and rotor. There
is 12volts to the coil and 12volts from the coil to the modual but nothing
out the top post of the coil. I've heard of buying bad coils so I have
bought 3 to this point.  The ignition fuse was ohmed and it is good. Is
there a sensor or switch that will stop the coil from firing, ie:
electronic spark control modual, fuel pressure switch?  HELP

I think an ohm meter and a repair manual would have been cheaper but hey
that's just me ;)

Agreed, but it's too late for him.

The harness to the pickup feeds the circuit.

The pickup triggers the module on and off.

The module triggers the coil to fire.

good in/bad out......bad part.
