Just lost all power


Many car fuel pumps trigger off the ignition coil, so you need to determine if current is getting to the coil when you turn on the ignition. A bad coil may give no spark and no fuel pump operation too.

BMW 530i 2001 engine struggles under load


If a coil was bad, it would be missing or misfiring. Could be a clogged filter or a weak fuel pump. To check have the fuel pressure tested. If pressure is good, a tune-up might help.

What is ASD RELAY


The power supplied to the fuel pump, ignition coil, fuel injectors, and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD); the idea is to shut off fuel pressure and the ignition systems when the key is turned off to prevent fires, dieseling, and other problems.



The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running, or if the turbo boost pressure reaches and exceeds the over boost cut-off point, the logic module cuts power to the ASD, which in turn removes power from the fuel pump, ignition coil, injectors and those parts of the power module. This causes the engine to shut down.


Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start.

1995 Ram 1500. Just died? No votage to coil, no spark?


The power supplied to the fuel pump, ignition coil, fuel injectors and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD):
The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running, the logic module cuts power to the ASD, which in turn removes power from the fuel pump,ignition coil, injectors and those parts of the power module.  This causes the engine to shut down.

Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start. The ASD can be triggered by a broken wire or short in another place, e.g. the fuel pump.  Hope this helps, and did you try to retrieve any DTC codes?? Be glad to help friend.
