If there is no trigger signal for the module, I might suspect the crank sensor. Are there any codes? Do you have B+ and ground at the module?

I have no codes and not sure what you are talking about B+ and ground on the module. Where is the crank sensor and can a person replace or repair this?

There is probably a single connector driverside at the ignition module. Take the connector loose, turn the key on, you don't have to crank it, use a testlite between the two terminals, if the testlite comes on, there is voltage and ground.

The crank sensor maybe located backside of engine block, down low. You may need to get under the vehicle to get at it. If you need to get under the vehicle, safely raise and support the vehicle.

I'm not positive that is the correct fuse block, you can check. Voltage comes from that fuse, the circuit goes hot when you turn the key on. You can't test ground unless one end of the testlite is touching voltage. If you suspect a ground issue, use another ground, metal part of engine. The key has to be turned on before you can check voltage to the module.
