Fao Volvo Z-Car Builders, Need Help Ref And Engine Plug/connector
Posted 30 September 2012 - 02:20 PM
I was hoping to start my Volvo for the first time this weekend, but alas yet another problem has popped up and I’ve no idea what to do!
Basically I could do with a BIG favour from anybody running a Volvo engine Z and the DTA ecu. Can you please have a look and see if your cam position sensor is plugged in? I believe it should be Pin 19 on the ecu, but the sensor on mine (3 pin yellow connector coming from one of the cams) is just coiled up and not being used!
I need to know if this is correct as i though the engine needed this input to allow a spark.
I've checked the z-cars wiring and everything else seems ok, I have 12v at the coils just no spark when I crank her over
Any help gratefully received

Try a search about it on here! I might be wrong but I was told the DTA s40 did not take cam sensor as a input. Luke

If that's not helping I may draw a little picture and get you to cross reference it with yours; again I'm hoping it will give me a simple answer and fix to the problem!
Thanks again though

Thankfully the old lap top still fired up as the new one only has USB ports and yet to use a USB to serial adaptor that actually works!

Anyway, just plugged her all in and I have a fail against both the oil and fuel pressure sensors, but as I don't have them connected it's no surprise; should be pins 23 and 33 on the ecu.
I've had a quick flick through the manual and it looks as though these are new inputs required by the ecu and that the engine will not start (no spark) unless set parameters are met, 3 bar fuel pressure being one by the looks of it.
I think a quick email to z-cars is required now as I need to know how they got around this for mapping, unless of course there is another issue i've not discovered yet!
Update.... No rpm signal either................ and the above shouldn't stop it from starting Hmmmmmmm
