does this happen every time or when the vehicle sits for a while? try this...before starting turn key to on position for a few seconds and then off and repeat 3 or for times before starting, listen for the buzz noise of the fuel pump, fuel pump only runs a few seconds untill the engine starts. Listen carefully for it to run and when it stops turn off and the back on listening for pump again, should start right up after 3 or 4 cycles.
