Spark Plug Wires and Distributor
'94 4x4 Sidekick with 1.6 L JGDHA engine
Next two pieces of information were quickly found on other websites through a google search.
Upper Block: Cylinder 1 is front and 4 is rear. |1|2|3|4|
Firing Order: |1|3|4|2|
If you're not sure of this: Turn engine by hand [pull on vbelt] until harmonic balancer timing mark is pointed up into engine block timing marks. Look at rotor. Cylinder 1 is the spark connection rotor points at. Keep in mind that spark comes a slight time after TDC so rotor will not be precisely pointed at connection. This should be as close an indicator as you need.
If you feel a need to check rotation direction: Pull distributor cap, run starter briefly while someone watches rotor movement.
Now for an old school solution to a problem I've seen others scratch their head over: weird misfiring.
When spark plug wires run parallel and too close to each other the firing wire can cause other wire(s) to also gain a spark charge. This noticeable weirdness doesn't occur if they are separated. Touching and very close proximity, especially with parallel orientation causes problem. I bought additional separators to more fully address this problem. Separators come in varying degrees of bling and, most importantly, specific wire diameter parameter. I bought three [zero bling] 7mm separators for few dollars.
So don't run spark plug wires wrong or you're likely to have weird problem with ignition. I was glad to remember something learned in Auto Shop.
All of this was written for entertainment purposes and I am not liable for any problem you experience. [Why did I post this final line? Think about it.]
