Hi everyone, a newbie here. I'm having starting problem w/ my car. I have done a basic tuneup w/ fuel filter replaced. Car runs fine except for the hard starts mostly when hot. Fuel pressure seems ok (35-55 psi). I have been advised to replace fuel pressure sensor but I cn't find it. Others say it could be the cam pos. sensor but no DTCs this time. Can somebody pls. help me diagnose this problem. Can't trust my local d(st)ealer. Thanks.
