just refitted the head to my 1.6 junior 16v Twin Spark,after the cambelt disintegrated (see cambelt woes).It needed 6 new exhaust valves-so i suppose i was lucky!Anyway everthing's connected up, but it just wont fire!It turns over no prob, but no hint of it trying to fire up. Could this Alfa CODE system have kicked in? Or does that also prevent it turning over as well? What about fuses, relays etc? Anybody got any ideas?
I've got fuel cos plugs are now wet.As for timing it's spot on-i used the alfa timing tools to lock the cams and also used the top dead centre dial gauge to make sure it was right.I did disconnect the battery, so will have to use the master key to start it?
try turning ignition on so light comes on but do not turn over engine. leave on 30 secs then turn off disconnect battery and touch the leads together. reconnect then try to start. Let me know if this works
it resets the ecu and clears all errors from its memory. I did it when I had the battery off my 155. When I put it back on the code light came on on the dash and no matter which key i used would not start. I got this info from this site a month ago. It did work. make sure the battery is disconnected and the ignition off when you touch the two leads together ( note the leads not the battery terminals)
However if if is the immobiliser then the light should be lit up on the dash when you turn it over.
It may be the timing is out by 180º (as someone earlier has said). I did this with a 75. The exhaust valve is open instead of the inlet etc. so you get no compression on the firing stroke. No will know if you have no compression as the engine will spin really quickly on the starter instead of the normal "turning" you get before the engine starts.
A similar problem faced me last November, turning over but not firing. It turned out to be a knackered CODE unit, which cost £70 approx. My CODE light stayed on and refused to go out, so if yours is too then this may be the problem. The new unit solved the problem, I think the keys had to be done as well.
I've got a spark but it keeps flooding. I gonna leave it 'til 2morrow to give everthing a chance to dry out.I'm not sure it's possible to time it up wrong by 180 degrees, because the cam locks make sure everthing's in the right position-hopefully!
Sorted! I'd timed it wrong - 180 degrees out as was mentioned. I'm impressed, goes very well to say the least , it's just a bit rough when it's cold and won't really idle properly. But when it's warm - well it just bloody well goes and goes!Thanks for all the advice.
