Hi .

Please don't buy any more sensors for the time being, if you don't have any malfunction codes after a good test drive then don't buy .

I suggest you first check your fuel pressure .

Pressure with key on engine off should be 47-50 psi .

if filter not changed in the past do this also .

Do the test then please get back to me .
