My first problem that ive had was a loose rotor (rotor and cap) cap was tight but not the rotor inside, the screw wasn't tightened enough, and popped out after a couple thousand miles, so it ate up my cap and rotor and was bogging a lot, then died. (luckily in my drive way) so i changed it and wont start now, i also changed the fuel relay, fuel pump and fuel injectors because when i would click the key to position 3, usually u hear a distinctive noise that the injectors would spray and the engine would start when turning the key over, but no sound and when turning the key over, wont start. So then i would click back and fourth from the 2 to 3 key positions untill i hear that distinctive noise from the injectors and cranked it when i heard it and then it would start after 20-50 trys, everything works fine when its on besides a high idle of 1.5 rpms it would stay at. (timing is good though) but when i would turn it off and then try to restart it, the injectors wont spray and wont start untill another 20-50 trys. i bought equipment for diagnostics because of this problem and changed a lot of parts that thought were the problem but not it and just need help of what else it might be, im leaning towards changing the ecu from the code it was throwing me (p1607 pcm internal circuit failure) but i really dont want to spend $900 dollars for a new ecu, so if theres anybody out there that can tell me something else that i dont already know besides changing the ecu please help

 

I have the same issue with my car.. P1607 PCM I.C.F. I have spent over $600 at two different garages and then another $200 at Acura to diagnose the problem. They told me I needed to get a new ECU and wanted to charge me around $1500. I was also told I had an OBD2 in my car and it was posible to change it with an OBD1.... But you still have to reprogram your ignition keys if you change it or the car will turn over but wont start. I don't know for sure if it will work for you but you should see if it might help... Im doing it to my car and it will only cost $450 plus the reprogram cost...

Good luck

A used ECU on the forums would cost you less than that.

 

You can find an OBD2 ECU online for much cheaper, probably between $100-$200.

And I think an OBD1 conversion would work fine, with the jumper harness of course. I don't think you would need to change anything.
