Question about 2008 Nissan Xterra S
I've been reading through the online forums and it seems that there are a lot of 2007-2009 Xterras with a similar problem. I have replaced the following, based on what was discussed in the forums. -Both Camshaft Position Sensors -Crankshaft Position Sensor -ECM Relay I replaced both the starter and battery a year ago. The battery I upgraded from the recommended 550cca to a 750cca. Spark plugs were recently replaced as well. The truck starts fine anytime the temp is over 50 degrees. From 35-49 degrees she starts after 2-3 attempts. Below 30 degrees, she won't start without a jump. I'm wondering if maybe there is a fault in the fuel relays, or a bad injector. It seems like the difference of 3 amps is causing the problem. I don't know what system in the truck could be drawing that extra power and preventing ignition. I plugged it into a code reader and it didn't give me any "hard fault" codes, but did produce a PENDING code P0603 - which indicates a pending fault in the ECM. Anyone have any similar problems or an idea of how to fix this issue?
IT IS POSSIBLE THAT THE TEMP SENDING UNIT FOR THE ECM IS NOT READING PROPERLY AND NOT TELLING THE ECM ENGINE TEMP CORRECTLEY SO THE ECM IS NOT ENRICHING THE FUEL MIXTURE FOR COLD STARTS
