95' NA - Cranks, doesn't start

fredt2 · Post by **fredt2** » 21 May 2025, 16:11

Hello once again, I did a rebuild on my NA in the past 2 weeks, due to a leaking valve and blown head gasket(cyl 3-4), as mentioned in a previous post, so I took it apart, replaced everything that was busted and put it back together.
Now, with everything back in place, valve timing aligned, it cranks without a problem, but doesn't start. Haven't had a single problem like this before.
It probably isn't sparking, but i couldn't pull a spark plug to check, as I was alone and needed someone to crank from the inside.
I know the drill, cam sensor, ignition sensor and such, but is there anything else that I should pay attention when check tomorrow? Any heads-up will be greatly appreciated.

The round plate that the rotor mounts to can be mistakenly indexed 180* off, which will cause a crank/no start situation.

Thanks, hadn't really thought about the rotor, I had checked the cam sensor round piece but not the rotor.

Cam position sensor back plate too.

I don't think the cam sensor or the round part that bolts to the cam can be installed backwards, took it apart yesterday and found no way to put it reversed, the slots on the round part are offset, so it only works a certain way, don't know about the rotor tho

Not backwards but,just like the one behind distributor...it can go in ...in two ways.
One way is a no start.

Well, this is embarrassing....
Turns out I wired the spark plugs in reverse order, in the process of disassembling the distributor i checked and saw that the wires were backwards.....put it back together correctly and she spun like a beauty, feels like a new car
