So, I was heading home a short while ago, truck felt like it lost all power. I coasted a little ways, it seemed to pick back up and felt 'normal'. I parked at the grocery and when I came out, it wouldn't start. It felt like it was trying but wouldn't.

I call my wife, she comes and gets me and I get my fuel pressure gauge and stick it on rail, KO and it's reads 58psi. I crank it and it fires right up. I did this 2-3 times.

It's in the driveway now but could it be the fuel pump? What are my options?

No codes or messages on the DIC.

As far as I know it's the factory FF pump. Truck has about 225k on it. I got the truck when it was at 130k.

1. Walbro 450?

2. Hellcat pump?

3. Replacement factory FF pump? (that's what's in there now)

If I do 1 or 2, what's involved with the bucket? Do I need a hotwire kit or are there other options? Do I convert to a return system for future use? What is the part list for that?

Thanks in advance everyone.

 

why not another FF pump? that might be the cheapest and easiest option.

 

I was thinking so but was toying with boost again in the future. :/

 

FF pump can handle a good ammount of boost easily

 

I know.

KISS. My motto.

Ordered a new FF pump assembly, ring, seal.

Thanks @terravast4 .

 

Sounds like if could be the fuel pump but normally if it shuts off you won't be able to start it unless you smack the tank a few times to get you home.

 

It was odd for sure.

At this point, I don’t trust it and am doing a maintenance replacement of the FP assembly and relay.

 

New Delphi pump and relay installed.


Lets see what happens.

 

Which pump did you install? Have a part number?

I need to put my fuel bucket back to stock and want a quality assembly, not some parts store junk
