If you stand in front of the engine, It will be the second plug from the front on the left
side of engine.
wire that as number one or pull dist. and fix.
18436572 #1 is on the d side front then 3,5,7 moving to the rear starting in the other side from the front its 2,4,6,8 looking at the dist. the #1 plug wire is the 2ed turning clockwise from the hot and tach hookup in the side of the cap
If #1 piston is up on compression (hold finger over plug hole to feel air while bumping starter) put something in and rotate motor so you can tell when piston is at top of stroke. With cap off distributer rotor should point to #1 plug wire. rotate dist. with coil wire off turn over engine and move dist to get it to turn over the fastest. plug in coil wire start and time it.
It will be a tan wire with a black stripe that breaks out of the wireing harness on the fire wall but close to the dist.
remove coil wire from dist. have assistant crank engine over hold coil wire with insulated pliers about .05 inch from engine look for spark while assistant cranks engine. if you have spark . remove a spark plug wire do same spark test if you still have spark rotor is good, if not rotor is bad or another problem inside dist. also you look for corroded or burned spots on rotor or dist. cap
Bad plug or Plug wire
Drivers side, front plug.
What engine and what year?
the firing order 1-8-4-3-6-5-7-2. okay this is the way i set mines. on the dist. the number 1 plug terminal (should be facing the cyl. bore number one) then from there go clockwise in the firing order. another way is to look at the dist rotor when the number 1 cyl. is in top dead center(be careful there are two top dead centers for ever dist. rotation). when you have the right top dead center then go by the dist. rotor to which every dist. plug terminal the dist. rotor points to, that would be number one plug wire then go clockwise in firing order.
Need to know what engine you have.
1,8,4,3,6,5,7,2.
Could be a faulty spark plug or spark plug wire.
