I am not a big fan of throwing parts at a problem and hope to get lucky with getting rid of a problem. On the other hand I keep a record of everything I do to my vehicles.
If you do not know when the: air filter, spark plugs, or fuel filter were changed then they are overdue. I did not mention oil or oil filter since they are an essential maintenance issue IMHO.
If the items I mentioned are all OK and it fires on the second attempt and continues to run I would suspect that you have a fuel regulator issue which lets the fuel pressure bleed down.
Next cold start turn the ignition to ON and leave it there for about five seconds then attempt to fire it up. If it does fire up that may further indicate a fuel pressure regulator problem IF the fuel filter is good.
IF it runs fine after the initial start up issue I am guessing that the fuel pump is OK.
