i need some technical/mechanical help. i recently bought a 94' sonoma 4.3 v6 engine code Z with a TBI intake. the problem is that the previous owner ( which is not a mechanic) was working on it and pull out the whole distributor assembly and mess up the timing also i think he also mess/mix up the spark plugs wires. now i don't know where is the #1 spark plug on the distributor cap. can somebody please send me a diagram or pic of the right firing order for my truck. also the cap is not number so i don't know which spark plug wire goes where. thanks!
