Opti dead?

I was driving around and then my car just shut off. I have fuel pressure and a good crank but no spark coming out of the coil. I'm thinking its the opti but is there anyways to check if it is?

Re: Opti dead?

First rule out the coil. Measure the voltage at the coil on the pink wire. Measure continuity from the coil to the ICM on the dark green wire. Check ground on the black wire to the ICM. Last, crank the engine and check the white wire going to the ICM for 1 to 4 volts on the AC scale. Then let us know what you find.
