Does the fuel pump prime? Is the CEL on? Any CEL codes?

Does the Blk/Yel wire attached to the coil and igniter unit have battery voltage witth the key in ON(II)?

Did the timing belt snap?

With the key turned to ON(II), does the CEL remain on or turn off after 2 seconds.

What voltage do you measure at the Yel/Grn wire attached to the igniter/ICM?

Does the Yel/Grn wire running between the ICM and the ECU lack continuity or have a short?

Click here.

Check the Yel/Grn wire for an open or short. If the wire is fine, try swapping in a known good ECU.

Are both the coil and igniter unit new?

If so, check the Ye/Grn wire. If that's fine, measure the resistance for each of the three distributor sensors.

What are you measuring and what are the units?

Plug wires should have 25 kilo-Ohms max.
