Randomly stopping (engine dies), gettin' mad Options

[kavo]

Well its been a long time since ive been on these forums (since I was a young dumb teenager looking to do sick mods )

anyway so my 6gc has been cutting out randomly with no warning. I will be driving along then the engine light comes on simultaneously as the engine cuts (all the other lights come on too) and I have to very quickly clutch to maintain as much momentum as possible and pull off the road. This has happened numerous places, on the way to gym, peak hour traffic and not even at the end of my driveway. THen I cannot start the car.

Sometimes I have just left it and came back several hours later and it starts fine, other times wriggle wires and itll run for 30 sec then wont for a few hours. Very frustrating as it has been a couple of weeks since it happened last, and when the car is running me and my dad (motor mech and diesel fitter by trade) cannot diagnose the problem.


Today when i was wriggling wires I pulled this plug, which has now disintegrated except for the actual connection. I will try and start it later but is this plug needed for the car to actually run?



anybody had similar problems with their car stopping like this? or knows what it is?

DO NOT JUST THROW PARTS AT IT< THIS WILL NOT FIX YOUR CAR AND IS JUST WASTING MONEY!

If you check the things I told you, you will be able to find out 100% sure what the problem is.
I am taking the time to give you professional advice plz take it.

I'm not throwing parts at it. Just investigating potential cost.
How can I use your advice if it seems to be working? I will check the spark etc, but if all is working fine that will just tell me that everything is working, no? As in I can only take your advice to check spark if it isn't working

I would also check the coil and crankshaft position sensor immediately after it fails(like before it has a chance to cool and start working again).

sometimes it hasn't even got hot before it has stopped (ie only running for 30sec) does this matter?

I will put money on it not being the Ign mod because its not a part that will have an intermediate fault, the only thing that causes intermediate problems are the wires 9/10.
I also mentioned the voltage regulator, as that is a part that you can have intermediate issues. This you can check if the issue is happening or not
I asked about the clicking as well, if you answer these questions I can narrow down the issue.

I would suggest a fuel pressure gauge, to check fuel because your pump can still pump fuel but if it doesn't have enough pressure the injectors will not open.
