It won't start

I have a 92 Toyota Pickup. It has been running rather ragged these past couple of weeks. And two days ago it would turn over and there was a spark, but it wouldn't start. Later that day it fired right up and ran great all day yesterday and today. I start driving it tonight and it just dies in mid-drive and it won't start again, there is no spark. All the fuses are good, and I haven't messed with anything.

Check the primary and secondary resistances of the coil-that's good.

Measure the G and Ne resistances in the distributor-that's good. Check the G and Ne signal at the ECM side- if its there-look for the Igt signal going back to the ignitor-Igt signal at ignitor-replace the ignitor.

The computer has to receive the Ne and G signals in order to issue an Igt signal to tell ignitor to fire the coil-No Igt means No Igf meaning no spark confirmation and also No injector pulses
