No reason to assume that no1 wire is in the correct "by the book" place, here is what you do, and you REALLY need to learn this if you are gonna work on these.
You need to do TWO things:
1--Determine when the no1 piston is on the compression stroke (coming up, building compression, and getting ready to fire)
2--The timing mark comes around every crank revolution, the compression cycle is every OTHER revolution, so you need to match (1) above with the timing mark.
This is EASY to do. Pull the no1 plug, put your finger in the hole, and use a remote starter button, or a screwdriver to "bump" the starter. On the starter relay, just jumper across the big stud to the smaller exposed terminal.
You might have to "go round" once or twice until you "get" what you are looking for. "Bump" until you START to feel compression on your finger. Then look for the timing mark which may not yet, but should immediately "coming around" to the timing marks. Try to bump the engine so the marks are somewhere between (estimate) 10-20 degrees before TDC.
Now simply pull the cap and look where the rotor is pointing, and carefully determine which plug tower the rotor is adjacent to
Plug your no1 wire into that tower, and go CW from there with the firing order.
