ok 1988 t2 if i remove the cas and spin it i get spark and injector pulse but when is on the engine i get no spark and no pulse ......... i checkd all fuses relays and everything looks good what can be the problem ??

 

airflow meter. for some reason they allow the ecu to not send the signal to the coilpacks to fire when they are broken. weird.


unplug it and see if she fires up, revs to 3k, then dies.
