just finish my swap
running into some problems
INFO:

99 cx hatch
99 ex COUPE engine wire harness (one pice )
obd2b to obd1 jumper harness
obd1 p72 ecu

THE PROBLEM :
well not getting power to ecu , i did a test light on the yell/black wire on the center connector of the wire harness and nothing AND NO power on the no.39 fuse in the under dash fuse box what could be . i have no spark nor the fuel pump is priming
help plz
and i when I turn the ingnition to the II I dont have a CEL light or anything like that
thanks

 

are all your grounds good? do you have the ground on the thermostat housing connected. that is the ground for the ecu

 

yea is connected

 

so?

 

recheck all your grounds (total of 3) and all your connections...without the proper grounds, some weird **** might happen

 

u mean the tranny ground the thermostat housing and the valve cover ground , ?
they all seem to be fine ,al

 

well then start from your battery and work your way to the wire for the ecu..find a schematic for your car

 

can someone tell me how to check stap by step if I'am getting power to my ecu , like wich fuse/relay to check step by step

thanks

only if u help me

 

if your main relay comming on? check to hear if the circuit is clicking, that means its opening, if thats not working you might have a blown main relay, check into that

if I have a blown main relay that means that atleast my cluster should be giving me a cel right ?but its not

 

try running a ground straight from the battery to the block. also if you have a hayes manuel- it gives you trouble shooting to test the main relay.

 

lights shude still comeon, if you have a blown relay you will kno, you can hear ur main relay come on when u turn the key, dont even have to start the car to hear it, if your gettin no power to ecu fuel pump and no spark, main relay may ahve sumthing to do with it, i just did mini me swap and i was having the same problem, if you have a kill switch with a spliced power wire (yellow n black one) re wire it correctly and check to see if your main relay is clickin when u turn key
