Civic EG

Edit and Revised for full details.

I bought an EG hatch shell, and swapped in an H22, along the way iv painted the car, did a wire tuck, and just got the car put together.

Today after I got it to crank, it wouldn't start. No fuel or spark, but the pump is working, after i shorted it. And i hear the main relay clicking. And I also replaced it with another and still nothing.

At the same time, Iv had a code zero the whole time. So I took out the p13 and out in my p28, same thing. Tried a pt6 and pt3 which are both accord ecu's, but they should still work to an extent. And still a code zero. When I go to check the code all I get is a zero.

Im using the civic harness and I have 2 connections not used. One is the one paired with iat witch I believe you dont need. The other is the one that goes along with the windshield wiper motor that sits on the firewall. I thought that was also emissions and not used.

I have no clue what could be wrong, could I have gotten something mixed up in the dash somehow. Maybe were the wires go into the fusebox. And the ECU fuse is good.

The thermostat ground I moved to the back of the thermostat housing, and out a wire from there to the original location just to be safe. The transmission mount I went from a bolt that attaches the transmission casing to the clutch housing. The main ground Is in the rear on the spare tire thing.

Please help me figure this out guys, Im diying to hear my car start.

Also...The ECU check light stays on. But I know its not the ecu already changed it out.

Also, I removed my SRS and the light is still on. Would this have anything to do with the no start?

I'd start by checking all grounds. thermostat ground especially.

Anyoe esle? Iv edited the first post to add full detail...

can you take pics of the unused plugs?

I'm unfamiliar with the H22

Il try and get some tomorrow, at work right now.

But the harness is off of a civic. Not sure what trim though.

Car cranks, And now the car starts.

Today I got outside before I went to school to look into a few things. When I did the wire tuck I made all the connections come through the firewall next to the heater hoses. And there is were 2 connectors got mis matched. Changed those 2, turned the key and the pump primes and everything seemed to go good.

Turned the car over, and a huge flame shot inside my interior from the hole were my shifter is going to go. Looked at the firing order and noticed I had the firing order off. Changed it and tried again. Car fired right up. Got it to idle and turned the car off.

Tried it again, it started for a second and shut off. Did this for a while until I got it to start agaain after I kept hitting the gas pedal. Not sure why its so hard to get it started. Il have to figure that out tomorrow. If anyone has any ideas?

Also im tghrowing a code 41, which i have because I have an AEM UEGO and I didnt do the fix because I dont have a soldering iron to solder the resistor. If anyone knows any other fix for this please let me know.

41 is o2 sensor. try the stock one and see if it goes away.
you may need to add a second bung for the AEM wideband and run them both.
