Crank no start.
I changed oil in my 2005 civic dx & when I was finished the car wouldn't start, it had power and cranked but no start than the green key disappeared from dash & hasn't return. I dunno what to do. There's no fob just chipped key and I've tried everything. Can someone help me please.

The dash lights can help indicate an issue.
Are any of the lights not coming on? Such as check engine light?
No check engine light would mean there is no power to the ECM
Check fuses in engine bay and under dash fuse boxes.
Check all the fuses with a test light or voltmeter
Check to see if you have spark.
Fuel injector pulse.
Does the fuel pump run for a second when the key is first turned to the on position?
If fuel pump does not turn on for a moment then could be a fuel pump issue?
Have you tried to spray some starter fluid into the intake (make sure to avoid the MAF sensor)?
Did it try to start?
Does the green key light turn off after trying to crank engine??
You can also, watch a few youtube videos on crank no start to get a better idea of what to do

Yes, after I changed the 3rd relay behind glove box the green key came back on after I pulled key out. I changed fuel pump already and nothing. Checked EGR, checked fuses, checked spark, checked almost everything you could imagine. Left negative terminal off & wrapped in towel, nothing. The only lights that stay on when I turn key are the oil lamp now & the airbag symbol. Everything else goes away. It sounds like it's struggling to start, all accessories work. I'm at a loss man. It's really killing me & it's my only mode of transportation so I take care of it. I had just finished oil changed & used Honda filter & when I went to start it for a minute it didn't start. No warning signs before hand either. I'll try starter fluid now.

So, you have spark? Fuel injector pulse? Fuel pump turns on to prime fuel rail (turns on for a moment after key is turned to on position)?
How did the starter fluid test come out? Did it try to start? Did you check for 5 volt reference? TPS?

It's my immobilizer. I can't do nothing. I'm gonna be at mercy of dealership, my battery was 10.4v & I thought that would solve it but nope. Put new battery in & green key flashes non stop to where it'll kill battery again. I've no clue why my original key stopped working outta nowhere.
