so a few days ago my car started acting weird, it would take a few seconds longer to crank than normal... then the next day it was taking foreever and didn;t wana crank a few times... then that night it finally just would not crank... today i went to where it was stranded and it happened to crank... and i drove it home, as soon as i got home.. it wouldn;t crank. i stll havn;t been able to get it to crank.

I have replaced the dizzy cap and rotor button... also the fuel filter...i can hear the fuel pump running so i don;t think thas it but im not sure.... also i took a plug wire out and held a screw driver to it using a pair of rubber grip pliers and it shocked the shit out of me... lol so i;m guessing it is getting a spark(not doin that again). so i;m stuck... i;m 60 bucks out and i dunno what to do... could it be the fuel pressure regulator? cause i read it is critical for startup.. please give me any advice you have
