Default Car wont start

Well I get off of work this morning after working 3rd shift, my car (its a 95) just cranks but wont start. I get a ride home so I can get some sleep. Then later I go back and it starts right up and dies, and just cranks again. I haven't check for spark yet or fuel, Im gonna borrow a buddies fuel pressure gauge and check that and check for spark. Any ideas why it wouldnt start then 5 hours later it did and then just died, and now wont start again?

most common problem would be a failed opti or fuel pump

It is getting spark. I changed the fuel filter hoping that was it, unfortunately it wasn't. I dont hear the fuel pump coming on so im assuming thats what it is. Still need to test it though. If that is the case which aftermarket fuel pumps would you recommend and which ones should I avoid?

Well i did the basic spark plug wire to header spark test, theres spark (hopefully enough) I just know I dont hear the fuel pump coming on. I guess I should test the relay first. I still need to get a gauge and check fuel pressure.

well you also need to get a om tester and test the opti harnes i think its a and d and both those need to be at 10volts w/ key in egn. also should test ign. fuse, and ground on the coil.
