OK i have a 1991 Civic Dx hatch. I just swaped in a 0bd0 d15b non vtec into it it came with everything to do the dpfi to mpfi converstion so i did it wired it up following write ups i got off the net now i have everything wired up rite and everything hooked up. But when i turn the key i get this... Click the link to hear the audio audio here i also get a buzzing sound from a realay under the dash..... any help will be greatly appretiated(sp)..

 

Sounds like your thermostat ground is not on. Got the same buzz from the relay under the dash on my 91 hatch when I forgot that ground. Can't hear your sound clip either.

 

ok my thermostat ground isn't on so thats the buzzing huh but the car still doesn't start... ill try to figure out another way to upload the sound clip...

 

If your thermostat ground is not on, you will hear the buzzing and your car will crank, but no start. Put the ground on and try to start it then.

 

damn if thats all it is im a be so PISSED i just brought a new dizzy thanks to the "parts house" ground this rite?

 

theres a ground wire on your engine harness thats suppose to be grounded to that nut on the thermo.

 

yeah what he said.

 

done she starts up but im getting 14 flashes from the ecu....

 

Code 14 is your Idle air control vavle (IAC). Fisrt hake sure you have it plugged in. If so, here is a little more info on troubleshooting it.

 

ok i guess ill give it a shot... im pretty sure shes pluged up...
