cranks but no start?

[deathdealer9mm]

My 03 will crank and turn over but no start? Replaced battery, spark plugs, throttle body cleaned, fuel filter and fuel rod replaced, still nothing. Will start fine intermittently, other times it takes awhile to eventually fire. Any suggestions??????

Have you had the car tuned recently? What about your core?

Bingo! The elusive Fuel Pump -- I was thinking this as I read the title of the post and say what had already been done. Disconnect the fuel line at the rail connection, have a catch basin/can/bucket and get someone to turn the key.

You can always check for pressure at the schrader valve as well. Lot less work then disconnecting the fuel line altogether.

+1, You can even hook up a fuel pressure gauge to the shrader valve on the rail and check the pressure against what its supposed to be. Kinda why its there.

Spark, fuel, compression has to be one of the three.
