Couple of questions about cossie problems
Hi all, I'm over in the restorations section trying to get my old girl sorted out.
(oldest rally Sierra time for some tlc)
Just a couple of quick questions that hopefully someone can help with.
The clutch has stuck to the fly wheel with sitting for awhile.
Would holding the brakes and turning the crank by hand (socket on the crank bolt) damage anything before the plate snapped free?
Or would it be better to wait until I try turning her over and use the starter to try and break it off?
The other question concerns the injectors.
They are greys and when I first got the car she ran badly and hunted until it was suggested that the pintle ends were cut off as they 'trapped fuel' I did this and she did run well afterwards.
After the rebuild a couple of years ago she wouldn't run properly.
The fuel lines were changed, the tank cleaned out and the injectors cleaned. She then ran and pulled well.
A couple of trips later she began to miss and then wouldn't run at all.
I asked injectortune to check the plugs they had cleaned and they said they were still fine.
Once I've cleaned out the lines again, she has clean fuel in, cleaned plugs and a new batt. I'll test to see if she runs, but is it possible that the uncut injector pintles could be causing her to run rich and stop?
The greys with the new ends on them..
Looking at the plugs it looks like she was very rich on 134, but 2 looks like it just didnt fire at all after the new plugs were put in.
So, I maybe barking up the wrong tree with the pintles, it may be electrical?
Cheers
And thanks in advance for any help that might point me in the right direction.

Hi 'the Youth'
The plugs were spotless when they came back from injectortune. They were so0tted up after a few runs and then (as mentioned) only being used to try to find the fault.
I havn't got the plugs with me, so cant say yet what type, but they were the same type as she has always had.

Those plugs are scrap, replace them
If jerking the clutch free does not work as described above, then you will need to access the clutch/flywheel area.
Get someone to press the clutch pedal down and if you can poke a thin screwdriver up in and try and prise the friction disc away from whichever surface it is stuck to. It shouldnt take very much effort, although you may need to rotate the engine manually and do this in a few spots to get it to break free.

Sorry for late reply, I didn't see there had been posts.
I'll be sorting new plugs shortly along with oils etc.
The clutch is now free, I pulled the box to free it and to clean underneath.
I have found one possible culprit for her woes, the earth strap from the body to the back of the power steering bracket was loose (couldn't see it, it just moved as I brushed past it)
I'm sure the engine not earthing to the shell would cause faults?

Hahah, yes adding the question mark did make me seem like a dimwit.
I knew when I saw it it would be causing faults, I was just asking if if a lack of/ or intermittent earth would cause a particular one, like a sensor not reading correctly or the injectors not being able to fire.

It could cause all manner of faults, you just couldnt say anything specific.
And it could cause an even bigger fault that if the engine is not earthed correctly...when you try and start the car and the starter needs a substantial earth path in order to function....it can try and pull it from anywhere else and cause all sorts of damage.

Found the problems. The crank pully had rust on the lugs. The crank sensor was corroded.
Cleaned one, changed the other.
She now runs.. On 3 cylinders, as the coil pack is toast. Haha, it never ends, but we're getting there.
(Oh, fortunately the lack of earth dosn't seem to have damaged anything).
