I have a 09 Acura tL sh-awd. I replaced the alternator like a month ago . I was low on gas so it wouldn’t start up but it cranked so I thought I was a fuel issue so I got two gallons so when I try to start it it won’t start but it will crank . I had no issues in the past besides replacing the alternator bout a month ago. I have power in the inside and lights working properly.Any ideas of my issue I’m thinking maybe the starter???

 

My thought was the spark plugs, when we’re they replaced?

 

haven replaced my spark plunk since I had it

 

Check the fuel pressure.

 

Test the battery and make sure the alternator is charging it. Also, clean the MAP sensor and PCV valve.
