1997 dodge ram won't start. My fuel pump does not run and coil won't spark. Iv'e checked fuses and relays and they look fine. Could a bad fuel pump cause the asd to kill power to the coil?

First check any ignition/fuel related fuses. Check to make sure you have 12 volts coming into the pump and coil. If nothing to the fuel pump replace the fuel pump relay - if you do have power to the fuel pump then replace the pump. If nothing is coming to the coil it is either an ignition relay or a wiring issue. If you have 12 volts to the coil but no spark then replace the coil.
Also the fuel pump/relay would not kill the coil.

A no fuel no spark situation sounds kind of like a mixture of problems.. your crank sensor should tell the coil to spark.. the cam sensor should tell the injectors when to fire. now if the cam sensor is bad it will shut down the fuel pump as will a crank sensor.

97 dodge ram stoped getting fuel want start

Check the fuel filter, and check for electrical power to the fuel pump. The fuel pressure regulator may be bad, but usually those fail by allowing full flow all the time, which leads to flooding on start, and a strong odor of raw fuel in the exhaust at low RPM.

Note: most modern vehicles (after 1982) are fuel-injected and have electric fuel pumps. They don't have carburetors; they have throttle bodies, which are somewhat like the bottom half of a carburetor.

My 1996 Ford explorer it was running fine the day before, it won't start. Seems like it wants to start. I plugged the code reader up and it wont connect. I'm stumped.

Check all fuses includeing main fuse if all good. While cranking check for spark if spark present check for fuel pressure , if no spark test coil if coil is good I would suspect a bad computer if no fuel pressure you have a bad fuel pump

1996 dodge 2500 v10 8.0 no spark and no fuel pump. Ran fine 3 days ago

Check the fuel pump fuse and relay, if it's OK, you have a bad fuel pump. About the no spark, could be many things
Ignition coil, distributor (if so equipment) , main shaft position sensor, computer problem
Good Luck

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.
