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).

alot ppl talk of this orange 12v wire to the ecu, but that is all they say.... so i don't know what to look for b/c there are like 4-5 orange wires...

and i have a shat box starter

A lot of cold start issues is fuel related in my opinion.

The colder it is, the more fuel it will take to start/run it.

There is something that is not sensing that in your engine.

Any good mechanic should be able to track that issue down.

^ you make a good point

i have thought of it being a fuel problem... but i have no clue on where to start looking...

get rid of the clutch interlock relay

wire the key directly to the starter

this may not be your problem, but i had the same symptoms, wouldn't start in real cold or real hot or if i haden't started it in a long time

easy 4 wire soder job on my ka in s13

late

Sounds like a bad Coolant Temp Sensor, check ECU for Code

I have the same problem on my sr and check for codes, nothing pops up.

this is an infamous issue. nobody ever posts of how they resolved it or if they did at all. same problem with my s14 sr20

i just had a thread about my ka not starting right. dave said to check the coolant temp sensor. that wasn't my issue but from what he described it as it sounds like it could be your issue.
