I would have started by checking the battery, battery cables, and grounds.

Does it crank? And, I found this;

Older (OBDI) models - Start with the ignition off. Within five seconds, switch the key on, off, on, off, on. ("On" is NOT "Start" and "Off" is NOT "Lock"). The check engine light will flash. Count the flashes. Each code is a two digit code, so a (for example) 23 would be FLASH FLASH (pause) FLASH FLASH FLASH (long pause). It will never flash more than 9 times, so watch for those pauses!

No start can mean a number of things. Cranks but doesn't start, doesn't crank, tries to fire, doesn't try to fire...... etc.

Describe in DETAIL, what you mean by no start.
