Also I have a Haynes type manual on EFI computers etc. It talks about the CA20 computer and the red / green leds on the side. And how you select fault mode and you can recall ECU faults by a series of flashes on the red LED. Cound flashes and then look at what it means in the book.

Can anyone confirm if the CA18 factory ECU software would be compariable to the CA20?

Or if anyone has instructions specifically for the CA18 computer.

Thanks

Been working on this problem for 3 weekends now and still cant get the CA to fire.

Turns over and intermitently will fire on one of the cylinders but cant get it to run. I have heaps of spark, heaps of fuel pressure to injector rail and I get a whistling of air into the intake as it turns over.

Running the standard ECU.

Checked the resistance of things like air flow crank angle etc as per the service manual.

Before I got to this point I found a short in the resistor for the injectors (Metal filings), so thinking at the moment computer may have sustained damage?

Red and Green LED are on on the computer the whole time when key turned to ON and while cranking. Is this correct?

Do have the cranking signal from key accross to ECU and power on all required inputs.

Ideas appreciated ... Cheers
