Well I've got a case of the dreaded dead peddle on my 98.5. I ran the codes got 6 back. Here they are. 1682 - 0622 - 743 - 1765 - 1693 - 0216 I think that the 0216 is the bad one right. Well if I need a new pump I want a hot rod pump. My questions are do they last longer the the oem pumps. Who has the best ones. How hard are the to install. How long can I drive the truck with the dead peddle problem. I put on alot of miles and I get a dead peddle once or twice a day. I'll order a pump tomorrow but I still need to use the truck.Any input is greatly appreciated!
Thanks guys,

If you go to the top of the page and click on tech facts you'll find code deff.,
Where are your gauges , fuel pressure , if I've got the right idea DO NOT DRIVE sounds like the lift pump going bad , if you keep diving and this is the problum you'll take out the main pump [ biger $$$ ]. for after maket pump inplace of LP check around I think that the Carter had prob.s . This all from just reading posts , not having the VP44 , not familier.

 

you can check the fuel pressure and such to see if the lift pump is workin. Its possible its dead, and cause the overheating of your vp electronics, or they just died from the constant heat cycles they have been threw. Mine died with a staedy flow of 16 psi. But once you see the 216 its pretty much over. that is the death code, very few times you see that and erase it and survive. As for driving it dont trust it, I ran with the code but no dead peadle for 3 days. On the rth day goin to work i got the dead peddle half way there. made it to work 40 miles out and shut it down. Started it up to leave at the end of the day wouldnt do nothing but idle and make tons of smoke. Just my experience.

 

Thanks Guys,
I appreciate the responces. I need to decide what pump to buy. I talked to Scott at Mass Diesel and he suggested I buy a stock style pump. He said that there isn't much of a difference between the stock pump and the hr style pump that he sells. Now I talked to Doug at Performance Diesel Warehouse and he said that the hr pumps that he sells are not the same pumps as Scott has. He also said that the guys that have used the pumps that he sells have found big power differences.I did tell Doug what Scott said and he said that there aren't many guys that know more about this game then Scott. So what to do. I know that Scott knows his stuff and it sounds to me that Doug is not new to this stuff either. I wonder have anyone that has installed a hr pump went to the dyno before and after the pump install. I would love to buy a hr pump if there is a real difference, but I work to hard for my money just to buy a hr pump just so I can say that I have an hr pump. No one tells me that the hr pump last any longer then a stock style pump. Can anyone tell me what pump will last longer?
Thanks,
Topper

 

I can't tell you that a HR will last longer, but from what I have read, they are supposedly comming with the newer electronic package that Fedex is using.

Please verify, I am just re-stating what someone else said, no real life experience.

Might want to do a quick search, not a whole lot of guys have them.

 

I have some mods in my truck, but trust me..there is a night and day difference in this pump compared to the stock reman. Most of the extra power is low-mid range which is fine for me since thats where I use the the truck most of the time anyway.

*edit...I see you have the EZ and 275's trust me, the HR pump is going to give you about as much additional power as those 275's did..in fact I think you can feel the pump power more so then the stix

 

Not doubting anybody here, but without Dyno numbers I have to wonder how much of that extra power being felt with the HR pump is due to being so use to running with a weak pump that it feels like so much more. I ran for a lot of miles on a dying pump and when I hooked up my Blue Chip Pump it to felt like a huge boost of power over what I was used to even though it was not an HR. Chip at Blue Chip Diesel also doesn't beleive that you can inrease HP with the IP. Acording to him your engine will only use so much fuel and the excess goes back through the return line to the fuel tank. All pumps on the market feed excess fuel to the pump. Using this logic I don't see how the pump could make a difference. Now if you got a huge set of injectors in there using that extra fuel I can see that.

 

Thanks Guys,
Ya know the way I look at it if your current pump puts out way more fuel then your truck can use how will a pump that puts out 10% more add power. Especially power at the bottom. I could see a top end improvement but at the bottom. I just don't see it. The thing is some guys say wow big improvement. So what gives. I know some guys will pay big bucks for something and it's automaticly the best. I would like to see some hard evidence. Is there anyone here that has any proof that a hr pump will infact add a significant amount of power. I see alot of threads about this topic and there are alot of claims of huge power gains (some say 60-80 hp) how can this be? Is it the fact that we have weak pumps and when we put on a new pump it wakes the truck back up? Or do we want to see big improvement so we do... Any thoughts?
Thanks guys,

What, no thoughts...

 

I have not got into that yr & problum , but it would seem to me that if your pump is bad and needs to be replaced than putting in a aftermarket that has a better rep. - more relyable , and able to make more HPs with other mods , then that sounds like the best opp. even if its just the relyable part, and then you can mod the truck to need the extra fuel , just trying to reinforce your HP jones.

 

Yea good point John. I'm bringin the ol'girl out to see Scott tomorrow (Thursday) I want him to go through the truck. I wanted him to take a look at the trannie anyways. I had a local guy go threw it and put in the BD converter and valve body but I'm not real happy with the way that it shifts so I may as well bite the bullet and let Scott have a crack at it. I will have him install the pump and may as well have him toss in some gauges and what the heck maybe some power mods while the truck is there. I should get the truck back Sat. morning.

Not hard evidence, but good discussion. Check out Don's post- #21

Thanks Phatboy!
That's good info. My truck is at Mass Diesel now. I left a nice list of stuff for Scott to do.
Thanks again,
