My grand am has been running great until recently. Whenever my car is off for a few hours and I go to start it up, it is very rough to start and sometimes stalls. Altough the second try it normally starts right up. Could this be a fuel injector problem?

I would check to make sure that the vehicle is holding its fuel pressure for extended periods of car off and make sure before its started that vehicle fuel pressure is holding good.

Try this.

Turn key on wait for pump to turn off then turn key off back on and repeat 4 times then try to start. Fire right up?

After pump primes pinch off the return line. Does it hold?

If it holds pump up pressure again and pinch off the in line. Does it hold?

If neither way holds its the injectors.

Well I tested my fuel pressure and it was down to 30. I changed the fuel filter and helped but still did the same thing once in awhile. May test the fuel pressure one more time otherwise its probably the fuel pump. Great $300 fix haha

Sorry to hear that you may need a new pump. I wouldnt get a cheap pump or you may be replacing it again in a few years if your lucky.
