A friend of mine was about to junk this civic just because it stopped turning on a few months ago. I decided to take it off his hands in the hope I could keep another car on the road, I know some people who could use a cheap car.

Scenario 1:
- I turn the key to the acc position, lights come on, dash lights up, radiator fan starts blowing, fuel pump primes, etc. I give it a second.
- I then attempt to turn the vehicle on. It turns over and over and over but won't start.

Scenario 2:
- From the completely off key position I just immediately turn the key through the acc position and immediatly attempt to turn it on
- the engine catches and fires up for a second and then dies even if I'm revving it.

What I've tried:
- replaced crank position sensor
- replaced fuel pump
- unplugged the air intake sensors idividually to check for changed behaviour, there was none

I'm worried maybe it's a timing thing but this behaviour is odd to me. I'm not experienced with Hondas.

Scan for codes even if the CEL is off. Could have jumped time. You can pull the timing cover off and check.
