:angry9:
i finally put a b18 in my 1997 civic dx
happy camper until i attempted to crank it and realized

-im getting no spark
-im getting no fuel
-ecu is not communicating with my obd2 tester(used original d16 ecu obd2 to test)
-main relay is not clicking
------------------------------------------------------------------

random info

-All of my grounds have been replaced
- check all of my fuses with a test light
-im using a obd1 ecu with a jumper harness
-the car was originally and auto, so used a auto d16 harness but wired the 3 wires on the auto shifter plug to "put the car in park" so it can start
hmmm thats about it

im confused at this point:SuicidalSmiley:

_today i took out my main relay to maybe test it? it smells kinda burnt, i just did not want to go out and buy a new one with out testing it..

------------------------------------------------------------------------
If anyone has any experience or advice on the above matter please let me know!
thank you in advance

it might be the main relay if it smells burnt that could definitly be a problem my cars obd0 but when my main relay was bad i wasnt getting any spark or fuel like you said so try and change that out and hopefully it will fix your problem

just go to a junk yard and get a main relay, alot cheaper that way
