Re: 02 civic not firing
Very informative. Did it fire before you changed the cam and crank sensor? If it did you put something back together wrong. Double check everything you took off and installed back on. Is it an aftermarket cam you put in?

Pull a spark plug. Is it wet? If its wet you are getting fuel and its probably a spark problem. All of this is assumig the car is cranking. The more information you give the more we can help.

Exactly.
@phj
Why did you change those sensors, anyway? Were you getting an MIL (check engine light) and DTC (code) saying there's a problem with those components, or are you just guess-wrenching?
More details about what went wrong, how you determined the problem to be those sensors, what symptoms (other than "not firing") you're experiencing, etc. will help people give you better feedback. Your posts lack specificity.
Is the fuel pump working?
Does the car turn over?
Is the "little green key" light in the gauge cluster flashing?
Have you changed ECU's or keys recently?
Details, man! We need details!

Re: 02 civic not firing
Did you check for codes?
Tested the fuel pressure?
Tested the main fuel relay?
Does the fuel pump even come on when you turn the ignition on?
Checked fuses? Specifically fuse #6 under the hood?
What about fuse #1 under the dash? That one is for the ignition coils.
How did you check to see if it didn't jump timing?
How did you come to the conclusion that the CMP and CKP sensors needed to be replaced?

Re: 02 civic not firing
These cars don't have distributors.
And you're positive that fuse #1 under the dash is good? Have you tried changing it just to see?
Have you tested the ignition coils to see if they're receiving a signal, or are you just guessing that there's no spark since the car won't start?
