1992 chevy with a 305. i was driving it the other day and i turned it off and it wouldnt start again i waited a while and it finally started again i got it home and now it wont start again it has no fuel and no spark but the fuel pump is running but the injectors aren't pulsing

 

i can almost guarantee its the modual its in the distributer it right under the cap, 2 small bolt/screws removes it just make sure you lube the bottom of the new one and dont touch it with your fingers

 

Will be ignition module . Like Joedirt said .
Only other thing if it cranks back try temp sensor.

 

Ignition module.........replace it......make sure it has plenty of dielectric grease on it to help with heat dissipation.
