clueless, need some serious help

i have a 91 dodge stealth (base model sohc) and about a month ago i pruchased an aftermarket clutch .. 1st stage. anyways it messed up on me a few days ago and i have no clue what might be wrong with it. its got pressure in the pedal when the ignitions turned off, but when i turn it over i lose tension in the pedal, and it wont go into gear. and yes it does have fluid. if anyone has any idea whats wrong with it, please tell me, even though im probably going to feel like a dumbass afterwards.

it looses pressure, or threre's not pressure at all?

loses pressure, think it might be a leak in the slave, or in any of the lines?

could leak from any of 3 places: master, slave, rubber hose.

for the slave, check for fluid on top of the tranny just behind the motor mount or even underneath the tranny. for the master, crawl under the dash and look to where the clutch pedal rod goes through the firewall. there is a rubber boot there, and check if there is ANY sign of leaking fluid out the boot, or leaking down the firewall into the carpet. signs of the clutch hose leaking are harder to detect, but usually the problem lies with the master or slave.
