s14 sr20de in s13 cold start issues

[sideways performance]

i guys,
I browsed through the threads and don't find any that could help shed light to my problem.

I am currently facing a "Cold-Start-Problem" (i think). I find it very difficult to start the car first thing in the morning and when I left the car parked for > 4 hours. The starter cranks but the engine just won't turn over. I would need to crank it 6-9 times before the engine kicks in. Flooring the gas pedal only works occasionally. Once the engine starts up, subsequent start up is a breeze (until I park it for > 4 hrs or so).
