If you turn the ignition key to RUN and do NOT continue turning to the START position, the powertrain control module (PCM) engages the ASD relay to provide power to spark coil, fuel pump relay, etc for about 1 second. If no signal is received by the PCM indicating crankshaft rotation, the the PCM de-energizes the ASD relay. This is normal operation.
What is the issue? Do you continue to turn the ignition key to the START position, the starter is spinning the engine and the engine will not start and run? If yes then you need to check the wiring between the PCM and the crankshaft position sensor and the PCM and the camshaft position sensor. The PCM is not receiving the proper signal from either or both of these sensors.so as to energize the ASD relay continuously.
