Good morning and welcome to JustAnswer!!

My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 19 years and I will do my best to help.

While 15 psi is low it's still within spec.

CHECKING ENGINE OIL PRESSURE

1.Remove the oil pressure sending unit and install gauge assembly

2.Run the engine until thermostat opens.

3.Oil Pressure:

  1. Curb Idle-25 kPa (4 psi) minimum
  2. 3000 rpm-170 - 758 kPa (25 - 110 psi)

4.If oil pressure is 0 at idle, shut off engine. Check for a clogged oil pick-up screen or a pressure relief valve stuck open.

If the oil psi goes to 25 psi when your @ 3k RPM then your ok and with spec..

If your not familiar with how JustAnswer works, You ask a question, I try and give you the best answer I can and then you leave a positive rating so I get credit for helping.. I strive for excellent ratings and greatly appreciate all bonuses.. Feel free to reply back as many times as needed until your issues is resolved...

I AM VERY GLAD THAT I TOOK A CHANCE ON YOUR PROBLEM SOLVING SKILLS. I WAS SUCCESSFUL IN REPLACING THE FUEL PUMP. MY TRUCK RUNS LIKE A CLOCK. IT RUNS LIKE THE DAY I BOUGHT IT.

I GIVE YOU ALL THE CREDIT FOR YOUR DIAGNOSING THE PROBLEM, JUST FROM THE SYMPTONS I GAVE YOU OVER THE e MAIL. I WILL USE YOUR WEB SITE AGAIN AND REFER MY FRIENDS. THANKS SO MUCH FOR THE HELP.
