Q.1993 Acura Integra LS 4 Door, Automatic; Starting problem. This has been ongoing for over a year. Cranks fine.
At first it was just occasional. Would have to leave the key in the on position for 30 seconds up to 15 or 20 minutes.
The amber check engine light would stay on during this time. Finally the light would go off, the fuel pump would cycle on and the car could be started. Now it has to sit with the key on for hours or a day. I just got it to start a few minutes ago after the key being in the on position for hours. It starts and runs perfectly once the check engine light goes off.

Here is a list of what's new/been done to the car over the past 16 months.
Fuel injectors are new, old ones leaked.
Fuel pump is new, old one was weak.
Main Relay is new, I have three, had them tested by a company that rebuilds car computers, they are all good.
Distributor housing replaced (the integrated CKP, TDC and CYP sensors seemed to be putting out too weak of signals).
Passenger side computer (ECM? ECU?)rebuilt. & More (see the further details),
I am aware that this issue may require some time to figure out. I will click "Accept" accordingly (not just once). I live on a small island, no Honda/Acura dealership, and very limited amount of knowledgable mechanics.

Addition Intermittent Starting Problems. Can't seem to pin it down.
