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.
