i have a 94 hatch with an ls swap and is turbocharged, the pronblem i am having is that it shuts of randomly. and will not start until i pull the fuse for the ecu and put it back in. it does not blow the fuse it only needs to be "reset". it did this before putting in the turbo i am wondering if anyone has had a similiar situation and or knows how to fix it. thank you for your help

when it shuts off, does the car still crank over? Can you hear the fuel pump "prime" when you turn the key off, and then on again?

it still turns over, i know it doesnt get fuel i took the fuel line of the fuel rail last time it did it and turned the key on no fuel came out of the line. (sorry should have put that in the last post)

I haven't "seen" this happen, but it makes sense that it could. Maybe your main relay is so bad, that it actually looses internal connection while the car is running.

of course they do it when the car is off, and thus the car won't start, but I've never seen them do it while it's running. But that doesn't mean that it doesn't.

and maybe it's just coincidence that when you pull the fuse, enough time passes that the relay works again.

As far as the ecu goes, there is no internal fuse, nothing that would cause it to shut the engine off and not start again without resetting it. At least not without throwing some sort of code.

I really don't think that your problem is the ecu.
