1990 honda crx problem help.?

Ok so my crx (1990 honda crx) was throwing a code 16 and won檛 start.

Here is what I have done so far.

1. Replaced spark plugs, wires, distributor rotors, and cap.

2. Replaced Battery.

3. Replaced fuel filter.

4. Replaced fuel pump.

How problem started.

Problem started about 4 months ago. The car would run find while driving but once I turn the car off, it would not start. I would try a few times and then battery would die, and I would have to jump start the car. Every time I jumped it, it would start right up.

It got to the point where the car would start, and I would drive it, and when I turned it off, it wouldn檛 start for a few days. After about a day or 2, it would start right up again and repeat same process over and over.

Fixing process.

I finally decided to tune it up a bit. I did a full oil change, replaced the spark plugs, wires, distributor cap, rotors, and fuel filter. After that, it started right up again and ran find for about a day. On the second day, the problem came back again. I noticed that when starting the car, the check engine light would come on. Now when you first turn the key to the on position, the check engine light and all the other lights come on, I know this. But it goes off. What I am saying is during the starting process the check engine light comes on again. So I looked at the ecu and it was throwing code 16, which has to do with the fuel injectors. I was told to test the injectors?resistance with an ohm meter. The primary injector should be showing between 0.6 and 1.6 ohms, and the auxiliary should be showing between 0.6 and 10 ohms. I tested them, and both seem to be good.

I finally decided to get a fuel system cleaner. I put cleaner in and got the car to start. I ran the car all day without turning it off just in case. I even took it on the free way and ran it at high speed. After that, I turned the car off, and let it sit for about 18 hours. It was about 9pm at night and it was cold so I decided it was a good time to test the car. I tried to start it and it started right up with no hesitation. I then turned it off and tried it again just to make sure, and it started right up. So I drove it for about 5 minutes and then parked it again and turned it off and tried to start it again and it started right up again with no problem. So I figured the problem was fixed. The next morning, I went to do one last test. I tried to start it and it started find again, so I took it for another drive. While I was driving the car sounded like it ran out of gas and just died. I tried over and over to start it but best I could get it to do is start and then die 2 seconds later.

I towed it home and tried to diagnose the problem again. First I checked the fuel filter and it had some dirt in it so I washed it out with gas. I put it back on and tried to start the car and still no luck. I took it off again and noticed there was no fuel going to the car anymore. I noticed I couldn檛 hear the fuel pump either so I replaced the fuel pump. I turned the keys to the on position and waited a few minutes then checked the fuel line again to see if it had fuel in it and it had plenty lol. But I still can檛 get car to start. So now I am back here again looking for help to see what could be the problem. I am still getting code 16 on my euc. What i was thinking is to replace the injectors one at a time to see which one was causing the problem. If anyone has any other ideas, Please let me know i am stuck lol.1990 honda crx problem help.?
Ignition module is more than likely faulty. Common problem on 90s hondas. Located under the cap inside the distributor.
