my 99 GS just recently developed a hard cold start issue. when cold, i'll turn the key for the fuel pump prime, then start it, and i have to hold the key for at least 5 seconds to get it to start. i can then immediately cut off the car, and it will start fine. leave it sit for a length of time (like an hour or so) and bam, hard start again. I had a cyl 3 missfire the other day, when i mashed on the gas while merging on the interstate. I changed out the offending plug (noted what looks like a crack in the porcelain) but the hard start was still there, so that wasnt the sole issue. the plug was exremely white colored, electrode and groundstrap. I tried to smell the vacuum line for the FPR, but couldnt determine if it smelled of fuel or not... too many other smells going on. is there a way to test out the rest of the fuel system w/o having access to a pressure tester? i dont have one of those. any help?
