Alright, here is my night.

I am having a horrible night and would really apprecieate some help.

I have a 98.5 dodge with edge juice and intake and exhaust.

I just got my truck out of the transdminssion sho and i was driving home.

As the truck had a week in the shop, it gave me time to brainstorm some ideas.

I wanted the hot juice function for my chip, so i called edge and got the code.

Driving home, i stopped in the middle of the road and.....well i nailed it. Got up to 60 mph, let off the gas, and the TRUCK STALLED?????.

It just stopped dead, i rolled to a stop and that was that. I tried to start the truck, and it would barley crank, like it was siezing up it cranked like the battery was dead, and it did not fire.

I let the truck sit for 5 minutes and it cranked a bit faster but still did not fire.

I let the truck sit for 10 more minutes and it cranked normal and it did not fire.

So i am sweating, wondering what to do. I took the truck back to shop and wonder what to do.

I am thinking that my VP44 went and siezed up, Is this normal, do VP44's ever sieze up like this causing effects like this.

I pulled off the injector lines and cranked the truck over, and only one injector line was getting fuel all the others were dry, i mean dry nothing was coming out and i cranked it for a while.

The fuel pressure to the pump is 17psi, and after the vp out of the 6 lines only 1 is pushing fuel out.

What do i do, PLEASE any help would be greatly appreacieated.

The only thing that really bugs me is the siezing startup thing for 10 minutes?, do i need a new VP44?

 

Similar thing happened to me earlier this year, what happened to me was air got in the fuel line when I left off so suddenly. What I did was loosen the injector lines going into the engine, cranked it over a few times until I saw fuel come out, tightened it back up, and started right up, I thought my vp-44 was dead, but turns out it wasn't. Not sure if this is your exact same problem, but it did work for me and truck hasn't hiccuped since.

 

Vapor lock

 

A small shot of either will correct your problem, It will eventually start, but eaither will speed up the process!

 

I just got inside from working on the truck and i have some updates,.

I took off the line after the fuel pressure sensor and ....YEP ...lol she is getting for sure 18psi because i am still wet with diesel

I took off all 6 injector lines off the back of the injection pump, and cranked her over for a while, the vp is getting 18 psi. Only the bottom 3 outputs on the injection pump are putting out fuel, but they are just dripping out like one drop per second. NOTHING COMING OUT.

So basically my injection pump is pumping nothing. All 6 outputs on the back of the pump, only 3 are dribbiling, 3 are dry.

what now? could it be electrical but i was floored for 10 seconds and let off real quick in #6 hot on my juice at 60 mph. Did i sieze my stock pump?

With all 6 lines off the back of the injection pump, should it spray out, or dribble?

 

Dont over do diagnosis, I think you got a little to carried away too quick , hook your fuel lines back up, spray it with either, try it that way, Then look for another problem, Its rare a pump would just die! You would belive how many truck have to go to a shop because someone got carried away, and paniked

 

With the fuel lines ofd the back of the vp, and there is no fuel spraying out when you crank it for 20 seconds, Is that normal?
Should it spray out?
What will ether do if there is no fuel coming out of the back of the pump.
What should i do?

 

I've seen two cases like this, One i had no fuel at the back of the pump and one i had fuel at the pump, Both cases it wasnt the pump, Electrical harness. Thats why i recomend starting at the easiest first! its very common to come out of a hard load and vapor lock or fuel lock. Try either first, spray with either! Most of the time your pump would throw a code if it failed. Sometimes not, Just trust me when i say start simple first!

 

If it wont start and run with the lines on and starts when sprayed with either, you know its not getting fuel , then check your return valve!

 

One more thought, Did you tap your wire? Could it be cut into? Also , Do you have aftermarket injectors?

 

i had the wire tapped, and i took the tap out, i didnt check if the wire was broken.

Where is the return valve and what does it do?

 

On the side of the pump at the overflow. But have you tried to start it with either? Dont convince yourself it somthing major when its not!

 

hahahahahahaha!

 

FWIW, my VP died this exact way. It wasn't hard to crank, but I did coast from 120km/h down to a stop in gear, so there was no way for the VP to have seized and stayed that way. But the rotor and head were FUBARed. No fuel coming out other than drip from the bottom 3 says to me a dead pump, and gravity is pulling the fuel out of the pump.

 

any codes with the key on off trick?



where do you buy either at?
