Help with no spark in 5.7L TPI

Hi I'm having a serious problem getting my car started due to zero spark. I have plenty of fuel pressure and I have performed the following:

- Replaced Module
- Replaced Pickup Coil
- Tested the main coil off the vehicle and it gave a nice blue spark snap
- Checked distributor connections
- Checked ECM fuse

Background info:

- Plugs, Rotor, Cap, Wires all replaced about 2 years ago
- Has an older [blue anodized aluminum casing] Crane Fireball ignition box [possible culprit?]
- Fuel pump replaced last year

*** Car was running like new until I went outside one night to head to the bar and there was no spark whatsoever ***

Any idea's? What kind of symptoms would be shown if the ignition box has failed?

About 6 months ago, The rotor burned through and the car just stopped. New rotor and car ran like a champ. My cap and rotor were fairly new as well. Mechanic said it does not happen often but it does happen. Hope this helps

You should be able to bypass the crane unit if it has the bypass connections like the new ones. Also make sure the dist is actually turning, had a dist gear get eaten through so the rotor was not turning.
