Exclamation Wiring Diagram for Magneti Marelli IAW4AF.S2 Please!!

Hi Guys, I am new to this forum, but have been going around with a no start issue on a 2006 Fiat Panda 1.2 8V. I have tried everything, new crankshaft sensor, cam sensor, etc. Car has been standing for almost one year. Long and shorts of it I can confirm no power to coils and injectors. Traced one side of the circuit, provided earth signal to relay to trigger and send positive signal to coils and injectors, but also found that independant earth signals from ECU are not present. I need the diagram to determiine where the ECU receives power from (+12V IGN ON) and also if Cranking (+12V) signal is present. Any help with diagram would be appreciated and other suggestions - thanks

Hi daveofkent, thanks for your feedback, can you elaborate further about this alternator pulley. I did check the Valve timing and everything seemed ok, Is this pulley separate providing another input? I also measured the crank signal, using alternating current and there is definetely signal to the ECU. Would like to see the diagram if possible.

alternator pulley, behind front wheel on side of cam belt. 3 x 13mm bolts. If you didnt know better itd be real easy to put it back on wrong as it looks symetrical. There's a locating nipple thats easy to squash down and put in wrong place.

If you do car wont start, it'd force timing way out. From everything you tried though it doesnt seem youre getting anything but as you already replaced the cam sensor i thought that maybe you were suspicious of that at some point.

Did you get the car not working? or did it stop at some point

Hi, bought the car with a minor bump on right side, key was missing but everything else in tact. Had new keys coded, tested the complete set in another Panda, (ECU, BSI & Key) and that car starts, when fitting in my car, not starting. FPS was active but reset that, airbags did not go at all
