My turn now to post on this subject, (will all 4200 owners please stop laughing) Having just completed the knock sensor replacement - manifold off twice due to a water leak, the car started on the button and ran perfectly both times.
After removing the manifold again - replacing the leaking rad pipe, once again on restart, after a couple of spins (to repressurise the fuel lines) it fired and settled into a steady beat.
Whilst checking for any leaks and bleeding all the air (it appears the heater matrix is where it gets stuck) the engine just stopped. Thinking I had knocked something off a cursorycheck revealed nothing untoward I turned the key again and it fired up no problem. Dismmissing this as 'one of those things' I left it running for ages to check all the hoses etc, turned everything off and isolated the battery put my feet up and had several well deserved beers.
The next day we played musical cars to swap them around so it could go off for its MoT, the V8's steady burble compared to the rattly old tappets on a 1966 Sunbeam Tiger running on 3 cylinders (not always the same 3 either!)
Tuesday dawns - thinking I had locked the car pressing the keybutton an opening the doors sets off the alarm (incidentaly it never sounds just flashes the indicators and hazard lights), shut door, lock and unlock problem solved. Off to local garage no problem.
3pm - the manager who is a friend calls me, "The Maz wont start - spins over lovely coughed twice and now nothing"
After much head scratching when I get there and reading ALL the previous posts (there are a few) I concur that either the cam sensor or TDC sensor is at fault, I have neither on me of course but hope I can bodge a fix to get the beast home.
A neat trick with the vacuum hose from the cam sensor in mouth and she fires up and runs!!!.........for 3 minutes and stops - now nothing.
Questions are - where should the cam sensor pipe go? despite taking photos - i forgot about this I am sure it went on the nipple under the cover to the throttle body, despite the nipple facing the other way?
Does it matter which nipple the 3 (YES 3) vacuum pipes are connected to at the rear of the manifold?
Where does the the spare one at the front go? - I cannot find any where it may have come from and I dont recall disconnecting it.
This was taken not long after I bought the beast - when it was running like a dream
This was taken yesterday - where does the pipe go? when you blow down it it does not seem to have much resistance - i cant see what it connects to after the 'T' piece it just disappears down the side of the block
Incidentally after 8 hours its back on the drive courtesy of the RAC recovery (available with my bank account) 3 hour wait for a bloke in a van to say "it wont start mate" brilliant, followed by another 3 hour wait for the biggest flat bed truck you have seen to turn up - when it gets to my house the driver is not sure he can get the truck on the drive! - needless to say a cup of tea and some biscuits all is well.
