Good afternoon 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.

I work part-time here on JustAnswer to help you and other repair their own vehicles, and I get credited by your ratings.. So before leaving the site make sure and leave me a rating. You can still reply to me as many times as needed, even after the rating.. I will need for you to be my hands and eyes since I'm not there, and to be honest with today's electronics a scantool may very well be needed to retrieve the codes or to monitor data to see what's going on...

I see that your questions states that you don't have any power at the fuel tank. The reason is the lift pump is not in the tank unless you have converted it to the in-tank pump.. Has this been done? What is your VIN number?

No lift pump on block vin# ***** *****
Expert:  -Brad- replied 1 year ago.

Thanks for the VIN!!

What are you referring to when you say no lift pump on block? That there isn't a lift pump on the block? If so then yes that is normal because your liftpump is mounted to the fuel filter housing.. Can you disconnect it and see if it has 12v and ground? If yes then you will need a new lift pump or I would suggest to convert it to the in-tank pump setup which is more reliable..

It has been converted
Expert:  -Brad- replied 1 year ago.

Thanks for the reply!!

Ok did you convert it or did you have a dealership so it for you? And you have tested for 12v and ground to the lift pump in the tank? Can you jump the relay and make the pump run?

Customer: replied 1 year ago.
Dealership done the conversion no power at lift pump in tank
Expert:  -Brad- replied 1 year ago.

Ok if you locate the extra relay that was added which should be by the brake reservoir and see if the pins 30 and 86 have 12v when your cranking..
