car wont start randomly....

I have a 96 Accord EX 5spd...and sumtimes the damn car wont start.  I'll press the clutch in and turn the key, and i can hear the fuel pump relay click, but the car doesnt start.  Sometimes the car will start randomly, but most of the time i have to get it pushed start.  I thought it was the main relay, but it doesnt seem to be weather related, it'll start (randomly) when it hot or cold.  I have no CEL on or anything, so idk wat it could be.  Any ideas??  Oh yea, i thought my clutch safety switch was goin bad, but when i try to turn it on w/o the clutch pressed, i dont hear the fuel pump relay click, so i know the clutch switch is doin its job.

check your roller in the distributor cap

my car used to have this problem, randomly not starting and stuff
it ended up being the main relay
