D15b into EJ9 injector problems
Hello to all
I after a little help if anyone can assist me to evolve an issue ?
I have just fitted a D15B jam engine and gearbox into my sons 1997 EJ9
we used a loom from a eke vti Civic with a loom adapter for the ECU
the problem we have is the engine turns over ok
spark plugs fire as they should
but the injectors don't fire fuel (there is fuel at the rail)
if i squirt some juice straight into the inlet manifold the engine fires up it lumpy but obviously the fuel isn't metered or regulated.
I have checked the voltage at the injectors with the ignition on and its the same as battery voltage around 13.5 volts
injector resistance is 11.6 ohms
I have followed the injector coloured wires back to the ECU and have battery voltage at the ECU.
so i know the power is there.
If i earth the injector feed at the ECU the all inject as they should
Im also aware that they are controlled on the earth side
What i need to know is how to check where they get the signal from to inject at the correct time to inject fuel into the cylinders
Any help will be greatly appreciated
thanks in advance :nice:
