I am not sure how to read the voltmeter. However, the readings from each injector is 01.9 and 0.30, the ohms on reading on the O2 sensor was -1 and the same on the IAC valve

Ok injectors should ohm out at 1.5 to 2.5. You don't ohm the oxygen sensor. Now do you have power going to the injector? Did you get the timing set per instructions?

The fuel injectors ohm out at 02.5. The #2 injector is not getting any power. I worked when I connected it to another plug. I am on my way to a junk yard to get another injector connector and see if that will solve the problem. I noticed no ohms to each injector plug while the ignition was on. Is this normal?

I also exchanged O2 Sensors and IAC Valve, and still get the same codes. To include the one for the injector.

I did check the timing on the compression stroke. Everything lines up firing on #1 cylinder.

Thanks

Ok when you get the new connector let me know if it fires that cylinder back up. With the injector not firing it could throw other codes.

I got the new injector wire and no change. So I spliced it with another working wire and the car idles great but still misses and boggs down with acceleration. I still get the same codes.

Ok we need to test the injector resistor box. See pic below. Now what you do is unplug it and check resistance between each term to term A. Meaning check resistance between term B and term A then term C and term A and so on. Resistance should be 5 to 7 ohms on the 200 scale. If not replace that box. Refresh me what codes are getting?

I ohm the fuel injector resistor and here are the readings on the 200 scale:

Term A to B, C, D, E are 6.3
Term B to A 6.3, C, D, E are 12.0
Term C to A 6.3, B, D, E are 12.0
Term D to A 6.3, B, C, E are12.0
Term E to A 6.3, B, C, D are12.0

Ok these codes are all circuit failure problems. Now that we have the codes lets go through them one at a time and get this car fixed. THe care is telling us with the codes that there is power or ground problems. So first off it looks like that resistor box is responsible for you injector problem. However if we go from the code 16 for the injector then here is what we need to do. First reset the computer by removing the back up fuse from the under hood fuse relay box for at least 10 seconds. Second get a long screwdriver which you will use as a stethescope ok. With the engine running put one end of the screw driver on the injector and the handle end you will cup with you hand and put your ear to it. Listen for the clicking of the injector. Now if the injector isn't clicking then unplug it and ohm it should be 1.5 to 2.5 ohms. If this is good set you meter to 20 volt scale turn the key on engine off and check the red wire with black stripe on the injector harness and see if there is power. Let me know what you find here and we will go to the next step.

I reset the ECU and all of the injectors have a click and ohm out at 11.5 on 20 volts. I was so impressed with the way it ran that I took it for a test drive. I did not notice any hesitation, but I was afraid to punch it. I did notice the engine did idle up and down after it warmed up and then smoothed out. The engine light did not come on while I was driving. But a light indicating that all my doors were open to include trunk and hood while I was driving.

Great glad to hear it is running again. I would put to the test if it messes up let it do it now drive it like you would normally. Now as for the door indicator lights on I would pull fuse 27 in the under hood relay box and see if the keyless entry system will reset it self. Do it like you did the ECU reset. Let me know how it all goes.

I reset the fuse for the indicator lights and things seem to be running like it did before. I have a question, is the injector resistor still okay? If it is, I can't thank you enough for you help. It was awesome!
