so i installed 450cc dsm injectors along with a resistor box..got my p28 chipped connected with a brand new obd2b to obd1 harness..and with the new ecu i cant start it.no fuel pump sound or anithing..when i hook it back up to stock ecu i can hear the fuel pump..what could be the problem?
thanks

 

Year, make, and model of your car?


Any CELs?

 

and does it start with the stock ecu? if so all you should need is to wire a constant to the fuel pump and maybe a fuel pump switch in the middle so you lessen the chances of it getting stolen. but if the fuel pump doesent work that makes me think what else could be wrong with this chipped ecu?

 

Please don't listen listen to this. Makes no sense at all.


Just answer my question first.

 

you spelled crazy and boy wrong. Fixed your spelling errors and the car may work.

 

KRAZI BOI CAR NO WORK


your ecu is F'ed up or harness. obviously.

try another ecu with your chip

 

i've tried the chip on another p28 that i know is good and still the same thing.i've also tried two harnesses.one i was fishy about but the other brand new.when i put my stock ecu in it does start and just putters cause of the new injectors..when i was running with out the new ecu i had check engine light on but i also had it on when i had just the header on..now when i put my old ecu on there's no ecu, maybe it'll kick in eventually but with my new ecu a CEL comes on..just stays on and seems not as bright as it should be like the light is dying



2000 honda civic hx

edit: i guess im signed on as my brothers sn..haha..

 

Ah I knew. HX stikes again.

All HX's are use the OBD2A. Yes, that means 99 and 00 still use the OBD2A pin configuration on the plugs. Get the right conversion harness.

 

so i need a obd2a instead of obd2b? why are the harnesses different than the other 99-00's

 

I don't know why honda decided to do it that way, buy they did.


So ya, get a OBD2A conversion harness.
