Fuel Problem??

[M4Rl0N]

I have a 1990 240sx KA24e 186k miles, i recently replaced my clutch and a week after i started having this problem.

problem:
when i woke up 4 days ago to go to school i got in my car normally to warm it up so i can leave. The only problem was that my car wouldn't turn on. i would turn the key and it would crank but it wouldn't turn on. i have half a tank of gas and i can hear the fuel pump working, but for some reason i think it's a fuel problem because after trying and trying to turn on my car, all i can smell is gas. So today i got home and i check the fuel filter (i have a z32 filter) and it was fine it wasnt clogged or anything. So i check the spark plugs and they looked bad so i changed them to NGK and Gaped them .44 and then i tried turning on my car and then it turned on fine, for about 5 times at that moment. And then i drove down the street and it was fine. So i left it alone, i was satisfied. but as i tried to leave right now to a meet, the same problem started all over again.


I SERCHED!!!! and all i can find is that the fuel pump isn't working...but as I said previous my car did turn on???

Help would be very appreciated!

(if i left any needed info out, please let me know)


Thanks
