I just replaced the spark plugs, wires, distributor can and rotor in my 1996 Dodge Ram Van B3500. It starts but there is a vibration and an occasional clank with loss of power. I assume I mixed up the wire locations, but can't find a diagram to determine the problem.
Replaced distributor cap but have vibrations and loss of power on 1996 Dodge Ram Van 3500
In order to answer your question would need to know the engine size to locate the firing order.
It's an 8 cyl 5.2L
Look up the correct firing order on the internet, punch in 5.2 liter firing order in search and it will come up, next time if you do not know make sure you mark the wires, usually the firing order is stamped on the intake, make sure you pay attention to where #1 is at on the cap and the correct rotation for the wires. If not mistaken, without looking up myself, I believe it is 1-8-4-3-6-5-7-2, but could be wrong.
