I have a 2008 Nissan Maxima with approx. 160,000 miles.  The car has always served me well until last 2 weeks.  I bought it used around 10 years ago.  The first thing I did was change over to full synthetic oil.  Like you, I keep my cars for a long time.  First of all, was that a good thing or a bad thing?  My car started having issues when I start it in the morning.  The car has always turned over for 4 or 5 seconds then start.  Lately, I started turning the ignition and listen for the pressure to build up then start the car.  I checked on line and that is a sign of the fuel pump starting to go bad so I bought one.  Not only does it still take a long time to start, but the situation has gotten worse.  I did not go to the dealer and buy an OEM.  I will buy another one but before I do, what else could cause this?  I am worried that one or more of the injectors are letting the fuel into the cylinder which means the car is flooded.  In the past 2 weeks, I have ruined the battery from constantly cranking it.  What else can cause the fuel pressure to drain down?  I really enjoy your show!  It is nice to see someone in the real world explaining car repair instead of telling us to buy all the parts new!
