car shut of no ignition
i recently have a probleme with my engine.
it starts good but when i drive it it stops running very soon,today after 3km and yesterday even after 100 meter
it is really sudden like you turn of the ignition key.
so i don't think it is the feul pump,but i will check it anyway.
i gues more it is the ignition,i have a MSD systeme on it.
-soft touch rev controle
-Blaster High Vibration Coil
so i want to try to find out what is not working:
-is there a way to override the MSD 6T box?
-can i change the MSD coil with a stock?
yesterday after it shut down again,we did that test with the white wire that you have to ground.
if ground that wire the spark plug only sparks one time.
and if i have done this the engine starts again.
it is like the MSD box reset or something.
but the probleme stays there some time later the engine shut off again.
i would first check the connections -- the heavy ground lead and the thin red wire going to the ignition .
if you can post pics of your install, maybe i could see something .
ok thanks will check everything once again.
gonna take a picture of it.
maybe this will help you a bit further all ready.
i just tested by using a paperclip and grounding the white wire.
-the white wire grounding method gave me no spark at all.
-if a short the green and purple wire i have good spark.
also the car fired up straight away,did not drove it this time.
hope this might help.
here are a few pictures of my MSD set up.
this is in the back of my car.
normally are all the connections packed in shrink isolation but i took it it of now to see if i could find anything.
the green/purple and coil cabel are going tru different holes to the distributor.
is there an explination why i have spark with the paper clip method and don't have spark when i ground the white cabel?
and if a box gets broken is then most of the time comlete broken or is it possible that it has a bad connection inside.

any idea why only one of the tests is OK?
With the white wire, the spark is created when the short to ground is OPEN.
You have to do it fast enough to simulate minimum cranking rpm.
ok thank you will try the white wire again then.
but i test the same whit the two methods,right?
