Pretty sure it will still run on all 8 cylinders with a cam sensor down it will just not run quite as well and throw up a code
From my reading it seems it's uses the cam angle sensor as an input to the main ECU that then tells the ignitor when to send spark to the coil. So if the sensor is faulty, the car should only ever be running on 4 cylinders. You should be able to test this by disconnecting the plug to the sensor and staring the car (any takers that want to try for me?)
Funnily enough I tested 2 other cam angle sensors i have lying around in the shed tonight and both sat at around 1045 ohms.
Thinking about this, if the ECU is receiving a weak or no signal from the sensor it may not be telling the ignitor when to send spark to the coil properly, or at all.
Now I'm not 100% sure on this, but maybe the diagnostics just checks that the sensor is there with a complete circuit, not the actual pulse signal from it (which it might be getting anyway, just a weak signal) or maybe it checks for pulse, not the strength/consistency of the actual pulse.
As the page I posted says, I'll be replacing the sensor on saturday with one within spec. I'll post up results of various tests then. If it is just a coil I'll be happy, what would the luck be that I replaced it with a stuffed one?

Tom, the battery is dead and I don't have a charger at my place, I thought I'd gone through this. I will test the coil on the weekend, battery is on charge at in laws. But I am 99% certain that it fine anyway.
Sort of just following the repair guide. Again, I'll post results on the spark test on the weekend, any other tests I do between now and then will not involve the coil and will just be surmising of my readings and understandings of how the ignition system works. Ignore this thread until Saturday morning if it you just want me to do the spark test.

you are going in circles, half checking things, with no logical approach.
I think I agreed to this on Monday too! It's too hard for me to get anything done during the week Tom, I don't have a spare Soarer to test parts in/out of and it's too cold and dark to be messing around much past about 6pm (I get home at 5:30) If I'm "half testing" things its because I can not full test it, so I'm checking everything over to make sure hopeing to save some time later.
I will test it to make sure, but I do not think it's the coil. Someone has tried to fix this before and I'm almost certain the problem is deeper than that.
Unless someone wants to bring a running 91 soarer to my place on the weekend so I can test my coils/ignitors etc???

Got it up and running! Just took it for a spin around the block. Brakes need pads and the trans mount needs replacing, other than that. It's a really nice to drive car.

OK OK ,
Well as it turns out the rotor was missing a screw holding it down, so I'm fairly certain there was wobble in there enough so it wasn't sparking to the cap. Combine that with the ECU that I'm pretty certain was stuffed so I changed it out anyway and voila, one running Soarer.
The Cam angle sensor is still out of spec, not throwing any error codes at the moment so I didn't bother to replace it.
The exhaust needs some gaskets between the headers and cats replaced, must have been off at some stage, so there is leaking. Still have a hell of a lot of fuel I'm still working out of the system anyway.
But other than that, I'm good to take it to get registered. I'll be booking it in tomorrow.

Just did, 90% is coil, coil and more coil, sensors were debunked and I picked the faulty ECU from the start... oddly one fuel pump ECU for some reason..
I've had one of these cars before you know. Been around a while. Cheers for the help everyone. I'll see a few of you at the next meet and the rest I'll catch up with when I can!

Gahhhhhh!
"Alternator not charging" error message and it seems to have gone into limp mode again. But funnily enough it sounds like it's the OTHER 4 cylinders. Part of me is suspecting the Clip that supplies power to the top coil. It was smashed to pieces when I last saw it.
Got under and had a look, PS pump needs a rebuild but the alternator looks like it's is nice and clean.
Anyone have the part number for the coil clips and a PS pump rebuilt kit handy?

Gotta pull it all back to bits again on the weekend. I bet it's that clip, i should have ordered a new one and replaced it. Reading up last night apparently the drivers coil can throw the alternator not charging message. Or a stuffed Cat (could be collapsed)
Miles ahead of you:
PS Pump Rebuild Kit: 04446-24012 Coil clips: 90980-11246 (I think)

OK, OK Tom,
Now I'm starting to think it dropped a coil last night. Can't do a proper spark test until the weekend (missus couldn't crank a car if you offered her a million bucks) But the plug I was talking about is secure. Fingers crossed it's a different issue than before, although I wasn't getting an "Alt not charging message before" so that is kind of hopeful :-D
Here is a Protip: Pull the "INJ" fuse from the engine box when cranking. No fuel is delivered to the engine this way.

Ashley, just disconnect one coil and try to start it, then reconnect it and try the other coil. IF one of them if faulty the car won't start when the other one is disconnected..
