I bet you don't get spark. Distributor, Ignition Coil, Ignition Switch. Check em.
i agree, if hes getting all 3 then he wouldnt have a problem. most of the things suggested in this whole thread are valid things to check.

Im curious as to how hes verifying that he has fuel and spark.Your right,if he had fuel and spark it would at least try to fire.Maybe its a weak ass spark hes gettin.

possibly, but unless its a very high compression motor i think a weak ass spark should still be able to fire it up.
OP, have you hooked up a timing light to it?
spraying cleaner could verify if youre getting spark also (if it fires up for a split second). It might also tell you that your fuel pump aint working or getting power.

Yeah,i guess i agree,even a weak spark would get some kind of fire goin.He didnt mention how this started either.Did he go outside one day and it wouldnt start?Or were there some mods goin on and then it wouldnt start?
How are you verifying spark and fuel?

Thanks everyone. I sprayed starting fluid in the intake it started for a split second then died. So I'm guessing gas. I bought a brand new switch under the seat replaced it. The trunk switch is good. I replaced my fuel pump. Had a shop do it. It's stuck in the shop now. When I turn the key I don't hear fuel pump prime now that I put the new under seat switch. I took it out and rigged a toggle switch to see if my fuel pump turned on and it did. I'm thinking maybe injectors maybe?? I have no clue

perfect. now we know its a fuel issue for sure. where are you located? i had a computer fail after changing a battery. it stopped sending the signal to the relay for the fuel pump to turn on.

It is very difficult to diagnose a no start condition over the internet without seeing the car first hand. Every one of the suggestions made here are very valid. But before you get too crazy let's start with the very basics. From your description: your battery died, you charged it, put it back in and now you have a crank-no-start issue. You don't hear the fuel pump prime even with a new relay (unless you by-pass the relay with a toggle switch). You mentioned that spraying starter fluid in the intake you were able to get the engine to fire, albeit for a short amount of time. That's a good sign. It shows the engine has spark and it also shows that the injectors may not be pulsing. I am assuming you have the fuel pump relay by-passed and the fuel pump is on which means there is pressure in the lines and fuel is getting to the injectors but the injectors are not pulsing so fuel is not getting into the cylinders. The fuel pump relay and injector pulse are controlled by the PCM. Check your fuses and fusible links. Did you try jump starting the car first? Did you accidentally put the battery cables on backwards?
Because it sounds like you either popped a fuse (or fuses), burned a fusible link or fried the PCM. Like I said, it's difficult to diagnose without seeing the car. But let's go back to what you originally had, a dead battery. Any, and all electrical system diagnosis should first start with checking the fuses and fusible link (if present). Let us know what you find.

spray some brake cleaner in the TB. try to fire it after. Assuming you have spark.
And what would this accomplish?
FUEL
some of you dont understand what he means by this. if there is a fuel system issue, you spray starting fluid in the throttle body while someone cranks the motor. if it runs while spraying starting fluid then its definently a FUEL issue. at least then you can rule out ignition, computer, etc. and focus on fixing the actual problem and not wasting time and money on other things.
