My 03 civic cranks but wont start
Hello everyone,I'm new here and i need some advice/help.
20 days ago i went on vacation,i came back yesterday and wanted to go somewhere but my key wouldn't turn at all,my brother told me it happend same day i left and he was able to start it 2-3 times,when he turns car off,the key wouldn't turn into on position or start car at all.
So today i went and bought new key ignition cylinder (whole steering wheel component) and replaced it,now the new key turns fine,but got new issue.
The car wont start,it cranks,and all lights are on,but it won't start.Checked it on OBD2 and it only shows P0420 code,which i have for over a year,and that's all i get.
So my question is,why it won't start?What could be the issue?
Fuel pump,starter,or something else???
I checked forum,but couldn't find the answer.
I'm not so good with cars and fixing them,but i do have "some" experience.
Could use some more help,thank you all.

This mess is not programmed to the car (Immobilizer).
Tow it to the dealer.
I could have rebuilt the old lock cylinder....too late now though.

What he said..
Think of it as the key "unlocking" the ECU..your new key doesnt unlock the ECU anymore.
Some locksmiths could do it for you, but may or may not be cheaper then the dealer.

It flashes before,during and after cranking it but not angrily,flashes normally just like it did before,when you leave key in the ignition.
Anything i can do to bypass it,or the only solution is to take it to dealer?

The only time it should flash is after you turn the ignition OFF it flashes 5 times then quits.
Does the car have a remote start or is there some other reason the immobilizer may have been bypassed?
,or the only solution is to take it to dealer?
Dealer is the only game in town here for Honda.

no there is no remote start,and i really dont know any other reasons.

Re: My 03 civic cranks but wont start
Then my first reply will be correct.
The immobilizer and keys MUST be programmed before that car will run.
I see a tow truck in your future.
The owners manual explains how that green key light is supposed to act on page 81.

Re: My 03 civic cranks but wont start
Ask (nicely) if they can walk you through entering and using the "immobilizer brake code".
(The red BRAKE warning light MUST work when the handbrake is pulled.)
This would allow you to start the car and drive it to them, saving you a tow bill. The code would have to be re-entered every time you want to start the car so don't shut it off until you get it where you need to go.

thank you,i did that,asked them about it and they needed vin number,so they gave mi this brake code.
now once you start car with that code,and shut it off,you have 10 minutes to start it again,otherwise you will have to enter code again..
anyways,thank you all for help,problem solved.
key cyilinder online $250-$400,in stores $400+. junkyard $50 for whole steereng wheel component (airbag not included) and for programing it was $29 with tax,so total was $79 not bad
