Hey guys, new Honda Tech guy here looking for some help.

Long story short, girlfriend's brother had some guy install a D16Y7 motor from a 1997 Civic into his 1998 Civic EX, which had the D16Y8 motor like you all know.

PIC of the motor installed:





When I got involved into this mess, the guy who swapped it stopped communicating and what I've been told is that the car started and drove home but very poor and rough, and now the car won't start. So far, he still hasn't provided a list of the things that he's installed. I have experience working on cars but not really Honda's so I'm a little lost.

What I have done so far is remove the M/T P2P ECU and install a M/T P2E ECU. However, I found these two plugs that are not plugged into anything and the car will not start. I could use some help understanding what these two plugs are:



^Excuse my hand, I so pale.


This matches whats plugged into the engine block already, so I'm assuming it might be an oil sensor for the VTEC on the old motor? Either way, using my Multimeter it shows that its getting power when you try and start the car.
(Other connector in the motor):



I need some help understanding what I could try next. I checked the starter and its receiving power, but I'm wondering if its been burned out or something since these two plugs are not plugged? I couldn't find where to plug any of them in if I needed to. Any information that I could get or any advice would be super helpful.

Thanks!

 

Wrong forum should put it in the 92-00 civic section.

Hard to tell but that first plug looks like o2 to me maybe? What happens when you turn the key and try to start it anything at all? Search for "how to check 1998 civic cel codes" and go from there.

 

Sorry about that, I'll try to see if I can move the forum.

Nothing really happens when you turn the key. The starter used to tick but now it doesn't make any noise. It was a new starter when put on so I'm not sure if it's been burned out. Luckily her brother has a new starter if need be.

I'll check the CELs tomorrow when I get my obd2 reader. Thanks for the response
