Well i was out going to see the new movie 300, found an old plymouth something, sounded hopped up, he got on it, so i got on it, pulled on him pretty bad, which i kinda expected, we get to the next light behind a few cars, he punches it, so do i, my tires break loose (we were going about 15-20mph) i left off the throttle then bam, nothing no power engine shuts off so i pull off a side street, do a once over under the engine, make sure no fluids leaking, nothing, check hoses, all connected, try to start it, just cranks....

The same thing i had a few months ago when i had it replaced, so my best guess is my injection pump took a crap again, after being replaced in early november, now i know having my pump wire hooked up isn't that reliable, but 5 months? come on....is there a better solution? now the pump does have warranty, only problem is now i'm left without a truck until they can get me in and fix it again, but what can i do to ignore this problem, almost makes me want to fix it and say "Who' wants a 99 ram good condition?" cause this fixing is getting old. Now i don't want to take off mods...cause god knows how sluggish these things are with no mods on them...3.5 ton truck 215 hp at the engine, yea...lol

Anyways, unless i'm missing something it sounds like the IP is dead again, i'll loosen a injector line tomorrow to see if i get any fuel, but I really doubt it,

also when i first got it back, i was leaking fuel out of the pump cause a line going from the pump to an injector wasn't tightened all the way, but i tightened it and haven't had a problem since now....just wanted to spell out all the details, thanks.

Wanted to add, last time i had this problem it ran fine the night before, went out the next day to go to work wouldn't start, this time it died while i was driving, but was running fine right before, hope this helps if at all.

 

P-Pump it

I'd never own a VP-44

 

Crack the three easiest injector lines to get at, crank it over and see if it will bleed out some air and get running. Getting on it hard and then chopping the throttle may have done it, or so I have heard.

 

at this point p-pump isn't looking all that bad, except for the amazing price it would cost, and i don't have a turbo yet....but just wondering if there is maybe a upgraded vp-44 u can buy, not sure how reliable even one of those would be, wish i would have found a 98 12valve quad cab! o well.

 

Or another question is, is there a way to have power, but not risk the pump so much, i highly doubt, like another chip that will work well with an upgraded turbo, add lots of power, but not ruin vp-44's so fast.

 

- just curious, has your LP been keeping up to the demands of the box + injectors? I wonder if it has been starving the VP?

 

When i had it replaced a few months ago, they relocated it right near the fuel tank, how good that lift pump actually is i couldn't tell you, all i know is they put a new one on and relocated it, monday i'm going to ask them the details on the quality of stuff they put on...

One question though, i used to own a 3000gt vr-4 twin turbo, and a mod lots of people used to do is hot wire the fuel pump, what this meant was run a 8ga hot wire from the battery with a fuse to the pump, and wire it up so when they key was on the pump got full power, not from the smaller wire that the stock used, not sure if this would help out on that, but when i get the IP fixed this time i think im' going to look for a better Lift pump, since i guess there is nothing u can do about the injection pump just flat out sucking! any other ideas on how to prolong the life of the IP? with mods of course

 

What I have learned in the past few days of my VP disaster. 70% of the fuel sent to your VP44 is returned to the tank. So it is only actually using 30% of the fuel supplied. The other 70% is used for cooling and lubrication. I am by no means a "mod expert" like some of the guys on here but a stock lift pump with the mods in your sig and VP44's dying left and right with no mods I personally would have upgraded my fuel supply. Something which I plan to do. As was said earlier maybe your mods have starved the VP, using more fuel leaves less of that 70% to do what it was meant to do.....maybe.

As far as mods and power go I have been looking at staying away from boxes, chips and seeing if I could get around 300-325 with just injectors and maybe a turbo or at bare minimum a boost fooler. I'm just a little gun shy with messing around with a $2000 computer, that's just me though. I have to research more and see what my options are. That's just my opinion though. Somehow you would have to match fuel flow with your mods, in my way of thinking so you would know that when you had it all turned way up you would still be flowing enough fuel through the system to cool and lube.

Does this make any sense or am I just thinking out loud again??

 

What you said does make some sense, but as for staying away from boxes, i dunno if thats gonna happen :P what i was reading up on is that people are buying aftermarket LP's such as the BD one and installing them in conjunction with the stock lp, well mine has a relocated lp near where people are putting their lp, can i install an aftermarket one near this one and just run 2 lp's near the tank? or should i just replace the liftpump that is there after i have my IP fixed, funny thing is i was going to install a FP guage this weekend too.....guess it wouldn't have mattered much!

 

Well, i tried what one of the above posters told me, and loosened 3 fuel lines going into the injectors disconnected the batteries for a while, hooked the batteries back up, cranked it a few times, nothing, ok so i plug the map sensor back in, i had it unplugged since i have a COMP, tightened the injector lines, crank it about 20 seconds, and st arts slow, idles kinda rough, then bam, normal idling not sure exactly why it wouldn't start, any idea?

should i be worrying about something now? or upgrade something now so i don't have to worry? would it be safe to unplug the MAP sensor again since it ran fine without it hooked up? sorry for the many replies, just would like it to work fine, thanks again.

 

Im curious, what kind of fuel system upgrades do you have? From your signature, it looks like you relacated the lift pump.

The bottom line is that if you want to play you must spend the money and make the correct modifications. Its a pay me now or pay me later kind of situation.

Is your pump wire pierced??

Have you hooked up a scanner? What is/was youre fuel pressure at WOT?

 

To answer your questions

Yea my lift pump is near the fuel tank, it says Carter on the bottom of it, but other than that I don't know anything about it, I also have injectors as in my signature, and a 5 month old Injection pump, other than that no upgrades to the fuel system.

The pump wire is pierced, goes to the comp.

And i have not hooked up a scanner, I don't have one that can do fuel pressure, I just have a obdII scanner that reads codes.

 

Do you have a pyrometer and fuel pressure guage?

Are there any codes from the scanner?

 

Even with the correct mods you can lose the IP in a hurry,mine lasted 30k with the wire pierced,did not tap this one,seems to be hold up okay,I'd check into Bluechips pump,its been "upgraded" and comes with a one year warrantee even if you tap it (Using a cover)
No VP is going to live long without ample fuel flow.
Getcha a fuel pressure guage quick!

 

Don't even question it, get a Fuel Pressure guage and get a FASS system. You will see results in how your truck runs with it. That is one product that I will tout to anyone willing to listen.
