My suburban won't start sometimes other times it will start. The truck will crank without a problem. Tech at the parts store tihinks it is the fuel pump relay. I replaced the relay and still somtimes will satrt and run somtimes wont. Do I need to replace the fule pump. Don't want to drop teh fuel pump if it isn't the fuel pump an other trouble shooting I can do before changing the fuel pump.

Check the fuel pressure with a fuel pressure tester designed fo your fuel system to rule out the fuel pump
