Honda-Tech - Honda Forum Discussion - Car starting Problems Help Plz

I've been trying to figure what's wrong with my car, and I would just like to get any help please. I've searched, and found nothing has worked for me so far.

Car Spec: 92 Hatch B18b stock and stock ECU.

What happened before problem: Was just driving low speed and around 3k rpm only, but suddenly car dies, and won't start, just makes the "chugga chugga" sound.

Problem: High idle, low idle will die, won't start: The car starts sometimes, randomly. Most times it cranks but never start. When the car does start, it idles at a stable 2k but abnormal. When I tried to lower the idle using the throttle cable and/or throttle screw technique, the car idles too low and dies or just the idle stays high.

What I've done: - Check vaccum lines. all good.
- Main Relay using 3 clicks techinque all good.
- Battery almost new. good.
- Timing belt and Timing seems good, may have to check it again.
Don't think it's the timing though, or else car won't ever start right?
- Grounds should be good since car starts sometimes.
- dizzy good.
- new spark plugs and wires. checked for spark using ground
techinque. good spark.
- did the FITV to lower idle rpm, tightening the white plate with
springs. -causes idle to be more stable but still idle high.
- cleaned the IACV with carb cleaner. -changed nothing.
- fuel pump sounds like it's working.
- fuel seeps when i loosened the bolt, so there is fuel coming in.
but I don't have fuel pressure regulator to see if there's enough
pressure.

I really don't know why it randomly starts, and when i set it to idle low it shakes and dies, but when it set to idle a little high, just stays high. I think I did all I could possibly do except throw in the kitchen sink. any help or what I diagnosed wrong would help me greatly.
