Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

Yes, your best bet right now is to test the actual fuel pressure with a gauge.

Most parts stores will loan you a gauge for just a deposit.

Thanks, Ron

Had 52 reading on fuel pressure test kit yesterday. Shouldn't be fuel filter or pump correct?

You have a bad fuel pump. The specs are 55-62.

Thanks again and please remember to rate me now for my time.
