I'm working on a 2003 Mitsubishi Diamante 3.5l drove home the other night and parked. when i went to start it the next day it just cranked over and over. i could not hear the fuel pump running so pulled it out and bench tested it, it was fine. i received 2 trouble codes a P0340 and a P0335 camshaft sensor and crank sensor. Any ideas would be greatly appreciated
Codes P0335 and P0340 CKP and CMP signals were not detected for 2
seconds. The Cam and Crank sensor circuit may be shutting down the fuel
due to a non-spark condition.
Check the electrical circuit for something the 2 sensors have in common.
5v VREF to the sensor
Open or shorted signal circuit
Sensor power circuit is open
Ground circuit is open
I am getting spark at plugs i tried spraying starting fluid in intake and still no start. found 4 relays under dash in center which one is fuel pump relay?
