I have put a new distributor cap, coil and rotar on a 1984, 454 and am not getting any fire to my plugs. Was trying to find a wiring diagram to make sure that I had all of the wires hooked back up to the distributor cap. I have the firing order, but might have left some other wire off?

The firing order is 1-8-4-3-6-5-7-2.
The distributor rotates in a clockwise direction. The engine must be on the compression stroke on the #1 cylinder. Line up the timing marks. Remove the cap and the rotor should be pointing to approximately the 5 o'clock position.

Good Luck
