I just bought this car which initially was the O2 sensors that were messed up. So I fix those and camshaft sensor. Now the problem is fuel pump just barely installed my fuel pump in the car still don't want to start. I have no idea what to do because I don't know about cars from a female I need some help or questions answer something because my spark plug isn't sparking on the coil. So I don't know if it's all the coil pack or not I don't understand why my car don't want to start.

Hi,

Just want to make sure the theft indicator will come on and then go off after about 2 seconds when you turn the key on. If so, then we need start measuring voltage coming out of the ignition control module to see if the coils are getting voltage. I know you said the plug is not sparking so I assume you are removing the plug and holding it on the block and it is not sparking? If not, then we need to find out where we do have voltage.

If you don't have spark on any plug then it is either a blown fuse. Check fuse 1 under the dash. If that is ok, then the PCM is not commanding the coils on. This could be a PCM issue or a sensor input that is causing the PCM to not fire the plugs. At that point, we need to check for codes to see if that is telling us anything.

Let me know about this and we can go from there. Thanks

To tell you the truth I think its my ignition switch lock I bought from an auto shop used from another Honda Civic with key but when I called lock smith to program it the key said error so he wasn't able to program it so when I put old key next to the mobilizer and turn the new key which is foiled up it wants to start but doesn't. I did not know what to do about this problem because ignition switch is already in my car and I can't afford a new ignition. What do I do?

Just so I'm clear, you had a new key cut but it wouldn't program so you taped the old key that has the chip programmed to the other key and that is when this issue started?

Okay. Ignition switch would make sense but we should be able to test that. I included a quick test that isn't too bad to accomplish.

I attached the test previously. If you are not comfortable using a volt meter it may not be something you want to try. However, if you can disconnect the connector it shows, we can walk through this if you want.

When you disconnect the connector. Set your meter to the Ohms setting and follow through the steps on the second attachment. So for example, in the Lock setting, none of the terminals should have continuity with each other. Meaning when you put your test leads on any of the 5 wires the meter should read OL or no continuity. Then go to the ACC position of the ignition switch and you should only have continuity between the red/white wire and the white which are pins 1 and 2. If you put the lead on any other combination it should not have continuity. Then continue with the run and start position. You should only have continuity on the wires that have the little circle in the chart.
