mark lines up perfectly with zero and is not exactly on the location for #1. unfortunately i do not have a compression tester. a funny thing happened that i have never recalled hearing before, when i was looking at the spark directly at the plug on #1 obviously the plug was out and i was cranking over. engine fired and the "woofing" sound startled me. i just never had an engine actually start with a plug out. it didnt spray anything nor did it bark or flame.
question about these injectors. should they be tapping/pulsing or constant spray? should i be able to hear them. any reason why there would be two different style injectors for this vehicle? i have an extra TBI and i pulled the injectors from it just to swap out with the ones in the van and they are different.(every part of the TBI is identical but the injectors/openings)
