Default Cranks but wont start

Hi. I have an 87 classic celeb with a 2.8l. Fuel is getting to the injectors and I have spark from the coil pack. I also replaced the coil packs and ign mod. I'm still not able to get it to start. The car drove fine the day before it started not starting. If anyone could please give me some ideas they would be most helpful. And again thanks for any comments.
P.S.
I also have an extra computer for this car. I tried to see if there was any error codes and all it flashes is 12. I put the extra computer in and it does the same thing. The car cranks over and no error codes.

About the error code 12 , this is normal and that code just tell u that u enter the engine test field,

And about why it doesn't starting , I am not sure from that, but did u try to disconnect the ICV (Idle Control valve) and run the car on,

plz let me know if it still the same problem

Do a fuel pump pressure check, I had a fuel pump do that to me.
The injectors were spraying for me as well.

Remember to look at the electrical connections in th ignition system also because the pump maybe pumping and the injectors are opening but if theres no juice going to the coil or ENOUGH just going to the coil it wont wanna start also. A bad ground might also cause something.

Check all over the place for vacuum leaks.A little light went off when I was reading this....

One good way to find a leak like that isto spraystarter fluidaround the vacuum lines while someone else is turning it over- if it catches, you're close to the leak. Keep an extinguisher handy tho...

I will never forget a 1976 Impala that died next to my Uncles house. The line running to the power brake vacuum canister had gotten burnt through, resulting in a mass vac leak.
