The ECU is working, at least to some degree, because theres power to the idle control valve.
Ive noticed that the garage have put the coil in upside down. Theres spark, so its working somewhat. Other than making the spark, does the coil serve any other function?
No....if youve got a spark and with easy start sprayed into air intake your not getting a cough or fart pull a couple of plugs out and spray easy into cylinders put plugs back and crank and if you have spark it will fire...by the way is it the same vehicle your planning your French trip in that your posting in expeditions thread?...
