Hello All - new to the forums, I apologize in advance as I'm 100% not as technical with vehicles as most are here. Friend at work told me to check on these forums for similar issues I'm having with my Pathfinder to troubleshoot the problem. My Pathfinder has ran AWESOME to this point ( purchased in '09 ), has 188k miles on it, never had any MAJOR repairs done to it, ( check engine light has been on due to code P0463 - just dealt with no accurate gas level readings on dash for a while now ) just your typical maintenance. In the past month though, the car would die randomly while driving down the road/freeway, I would pull over, wait 10 seconds, crank the key, car would start and off I would go. Recently, it only runs for about 25 minutes then just shuts off and wont start again ( wait an hour, car starts, dies 25 minutes later ). I pulled the codes from computer, received P0463 - fuel level sensor circuit high input & P0340 - Camshaft Position Sensor Circuit malfunction. Checked recalls from Nissan, my VIN wasn't part of the national recall for Fuel Level sensor circuit high input. So off I went doing research to fix issue rather than taking it to a shop and spending arm/leg for trouble shooting/repairs. I started out by replacing the Cam & Crank sensors with OEM parts, drove down to auto parts store, P0340 is no longer there, just the P0463 code. Rather than just replacing the fuel level sensor by itself, I just replaced the Fuel Pump assembly all together with OEM part. After installation, ran for 25 minutes and died. Waited 10 seconds, car cranks but wont start - same issue as previously. Check engine light is back on, haven't ran car down to auto parts store to get code ( just installed Fuel Pump this evening ). Any help/ideas/troubleshooting guides would be greatly appreciated - I know most will probably say take it to a mechanic to get resolved but I'm trying to avoid spending $500 - $1k for labor cost - I may only have this vehicle for another 6 months at most when we purchase an Armada.
