after having my car sit for a week when on vacation my car now will not start. The car turns over fine but that’s it. I replaced the spark plugs but still no start. Also when i turn over the ignition you can hear the fuel pump turn on and prime the system. I am guessing that the pump is not fully working and is bad or it is the fuel pump relay. is there anything else that i should rule out?
Before randomly replacing anything else (spark plugs rarely create a no start condition), let’s determine whether your problem is no spark, or no fuel.
Spray some starting fluid down the intake and try to start it. If it runs for a few seconds and dies, the fuel delivery is being interrupted; if it still does not start, there’s a problem with getting spark.
