AL

checking for B+ voltage on the primary side of the coils when the ignition switch is turned on, and that the primary side is switching on & off when cranking.

it is an 86 non turbo, i checked voltage and i only have 3-4 volts going to leading coil, do you know where power is coming from right before the coils,
also i had a rat get hold of my wires going to my right head light, fixed that, and the starter cable was loose and making the car short out.
i am afraid something might be fried from that.

Pull the CAS from the engine and then key the car on. Spin it with your fingers. Do you get spark?

If no, then check the black/yellow wire at the leading coil plug for 12V with the key on. 12V?

If yes, then you have a CAS or ECU problem.

If no, then check the EGI fuse and main relay.

The CAS is held to the engine via one nut on the base.

I should mention that removing the CAS means that it needs to be restabbed correctly. Probably better to check the voltages at the coil first.
