b18b1 swapped into 1991 civic hatch, its not getting spark i went and got a new main relay it didnt work the new one doesnt click does that mean the new one is bad? i also look over at the ecu and it didnt blink any lights and i thought when i turn the key on it will turn on once, any help?!!? please

zeusdavis

Also i dont here the pump priming could a bad ecu do all this?
the b18a1 ran fine before i swapped the new motor in

zeusdavis

i tested the fuel pump plug and it has no power, Also the bottom dizzy plug has no power put the top dizzy plug does, What controls these, like i said there is no light blinkinh on my ecu

It's possible that the ECU could've gone bad. It has happened to me once. Here's the thread if you want to check it out:

If you don't already have an FSM you should download one and find the section for trouble shooting the ECU (and all else related, ignition, fuel pump, etc just in case it turns out the ECU isn't the problem).

zeusdavis

Anything else that I should check while I'm out their tonight? Come on guys I need a lot of help

Nick998

You swapped out and A1 to a B1? arent they different OBD's?

zeusdavis

Yes but that's not the problem people run obd0 on obd2 motors all the time

Nick998

So all the extra sensors on the B1 not being hooked up wouldnt make a difference?

zeusdavis

There arnt any extras on the motor

zeusdavis

Look guys im in need of alot of help, The car turns over it has no spark and the fuel pump isnt priming, i replaced the main relay and i tested for power at the plug of the fuel pump and i go no voltage, i have every ground hooked up. what could this be.

Did you try a different ecu yet? different dizzy? people cant just magically diagnose problems till you try the things they suggested then tell us what happened.

10psiLsEf2

get a electrician.
you wont fix it if you dont know how to work with wiring.

zeusdavis
