97 Grand caravan NO START

My caravan won't start. It will turn over but no juice going to the injectors or coil. There is juice going into the box beside the battery....but none comming out to juice the rest of the car. Any Ideas???? Thanks in advance:runaround:

Sure sounds like the Automatic Shutdown Relay (ASD) has tripped after a sensor failure or the relay itself is bad. The PCM will denergize this relay when it doesn't see data from either the crankshaft or camshaft sensor. When deactivated, the relay cuts power to the ignition coil, fuel injectors, fuel pump relay, and O2 sensors. The van will crank all day. Just won't start. You may or may not see the service engine light. First, I would tap on/reseat the ASD relay. You could try swapping the relay with an identicle relay on the panel, if there is one. Next I would check for error codes using the key dance or a scanner. A code could point you to the bad component or circuit. Trouble is, the sensors can fail without generating an error code. In any case, inspect the sensors and their connectors and wire harness. The sensors are cheap at around $20 and easy to change. Recommend the OEM sensors from the dealer. They appear to be more reliable.
