2000 ek civic with built gsr, obd1 ecu, won't start. It cranks and fires when brake cleaner/gas is sprayed into intake. When it does turn on, it idles good for a few secs and dies. Code 4 is thrown.

Spent 4 hours checking the car over and am stumped.

Any input?

 

you need 3 things

air
fuel
spark

fiigure out which one isnt working then get back to us

 

Here's diagnosis for code 4




I'd honestly try a good known working ECU if the one you have has been chipped as well even if its not one for the engine.

 

I drove my car up there, used my obd1 distributor pinned from obd1 to obd2, used a hondata, along with a computer to read the codes on a gsr base map, still did the same thing.

Some one said it could possibly be the dash harness??
