Hard starts
 

01 24valve 175k miles, hard starts when hot starts right up cold. Yesterday I started it hot put it in drive and it stalled started again once I started it and give it a little fuel like I was working air out or something I'm not sure.throwing p1693 code that's all

Stalling problem sounds like a fuel issue.

Sent from my dumb phone!

So what are you thinking? Air leak? Vp44 going bad, lift pump goin bad?

Hard hot starts is a symptom of a bad VP, but let's try less expensive things first.

What mods do you have done to your truck, specifically the fuel system?

The truck is completely bone stock. I just replaced the fuel filter to see if it was clogged, still the same problems.

It would be a very good idea to get a fuel pressure gauge on the supply to the VP44. Vp44's are prone to failure with improper fuel supply.

Yea, I would check your fuel psi, and you might start thinking about which LP you want... Fass is a good way to go!

I plan on getting fass soon just bought a quadzilla adrenaline v pulse 2. What would cause low psi and could that be my problem

The factory pumps just aren't good enough, it's that simple. They do not provide the flow to properly feed, cool, and lubricate the VP44. Adding a fueling box, like the Quad, will only make it worse.

Okay so what are you thinking s my problem vp going bad or is my problem I don't have enough fuel. I will not run my quad till I get a fass but will the fass fix my problem or am I in need of a vp very soon. If so I would like to buy the vp before I go spend 600 on a fass if that makes sense.

Chances are the damage is done. The FASS may make it better though. When I bought my truck, the previous owner had an Edge Juice w/ Attitude on it, and ran the hell out of it. With a factory lift pump. I though I was going to have to put a new VP in very soon. That was 3 years ago. I babied the truck until my FASS was installed, and it's been good ever since.

Wow thats weird my truck when I bought it had a edge power sticker on it. I garuntee he ran the hell out of it too.

So what would you do in my situation buy a pump or get a fass and wait it out.

I would start with the FASS, and see what happens. If you can get the pump diagnosed to be the problem, many vendors off a pump package. It would be the most economical route to go if you need both.

I want to bluechipdiesels or whatever it's called he has a method to diagnos the pump going bad. I sprayed hot water on the pump the electric Pratt of it on top of the pump. Once i did that it started right up.

I'm not sure exactly what the best choice is. I know the pumps going bad there's no other reason for hard starts and I did that cold water thing. Should I still by a dads and maybe be able to get like another year out of the lump? How long will it last do u think

It might save it. Sounds like the lack of fuel flow over heated the electronics. Most of the time the electronics fail in these pumps, not mechanical hard parts. Extra flow for cooling MAY keep it running, but no guarantees.

Is there anyway to relocate this pmd or whatever is on the pump?

Not that I have heard or seen of anywhere. Proper fuel flow solves the problem of electronics overheating 99.99% of the time.

Sounds good to me, I will be buying a FASS next week. Which is better in your opinion the 1 filter or 2 filter model? Just wondering because one is quiet a bit cheaper but has the same gph's.
