Hello,
I have a 1993 Chrysler LeBaron 3.0L with 85,000 miles. I drove the car to my house one night and shut it off. The next morning it would not start. The car cranked fine but would not start. Upon further investigation I noticed I had no fuel pressure. I jumped the fuel pump relay and the pump kicked on. I then tried to start the car again and with the pump running it still would not run. I checked for spark out of the coil and also have no spark. I'm thinking it could be a cam or crank sensor, possible ecu? Do you know any tests I can preform to narrow it down.
Thanks for the help!

They can be checked with a digital multimeter. It's somewhat difficult to check. I have a repair book for the '93 Concorde. The wiring on the sensors should be the same. Locate the Camshaft Sensor. It should be on the front of the engine and have an orange wire, black/light blue wire and a tan/yellow wire. Remove the plug from the sensor. Turn the key on. Check the orange wire for 8 volts dc. If that's ok, attach the plug to the sensor. Now backprobe the tan/yellow wire and the black/light blue wire with a small paper clip or straight pin. Connect the red lead of the multimeter to the tan/yellow wire and black lead to the black/light blue wire. Have someone slowly bump the ignition to turn the motor a little at a time. The meter should fluctuate between.3 volts dc and 5 volts dc as the teeth and slots line up on the sensor.
You can test the Crankshaft Sensor the same way, but it's harder to get at. The orange wire is the 8 volt dc reference voltage. The black/light blue is the sensor ground and the light blue/ dark blue is the signal wire.
