I have a 1992 civic hatchback cx which i just put a b18b in roughly a month ago. The swap was purchased from HMO.
I was driving down the road and it just cut out like you turned the key to off.
when i started it before i took off it was idling real low around 200 or 300 rpms
i headed off down the road and there was no problems at all.
and it just all of sudden died.
There is no spark from the dizzy.
I tried using my buddys dizzy of his usdm ls and it didnt work
I haven't been able to figure anything out.
There is also a loud humming noise coming from the wires running up to my driver sides lights
Before this the car ran 110%
any ideas?

 

so both dizzy's have no spark?check fuses

 

i checked all the fuses and relays

 

check your ignition system. The problem is most likely an electrical one

 

how do I check it? and what am i looking for exactly?
Thanks and sorry im not really good with electrical lol

 

Does it crank when you turn or no? Check the timing belt too, but if no crank or signal then you def. have a lose wire or ground that shorted something out. Ignition problems prior? Car stolen before?

 

it turns overs and timing is fine, not that i had at all, and most likely with all the stuff i keep finding with this car

 

relay
ig switch
ecu grounds

 

relay is fine
where are all the grounds
how do i check the ig switch?

this guide can be used to troubleshoot and or replace your ignition switch, go straight to the instructions on how to jump it to rule it out.

G101 is where all the important ecu grounds congregate, it is located on the thermostadt housing towards the rear of the engine on the passenger side.
wire brush the conector and the mating boss and re-install.

GL duder!

 

It isn't the ig switch
I'll clean up the connectors and let you know if it makes a difference

 

i cleaned it up and it still doesn't start

 

sounds like the same problem my buddy had... his car would shut off when he was driving.. he figured it was the ignition switch, changed that.. wasnt the problem.. he checked all his fuses and relays.. couldnt find anything wrong, they all checked fine... ended up being the Main relay.. he replaced that and hasnt had a problem since.

 

there was a wire disconnected on my ecu harness, they've all been hacked into
we got it running but now it completely melted the ACG fuse, i replaced it and it burnt it out right away

 

You have a short somewhere now. Trace your wires that are coming out of the fuse box.

 

Check all alternator wires (4P connector wires and large white that runs to the hood fuse box).

 

after looking around for awhile, the entire dash harness is all hacked and effed up
my main relay got incredibly hot and and the wires actually melted in is hand
im just going to replace the entire harness

 

Thanks for all the help guys!
