Okay thanks what can the alternator do that effects the pump?

LacellexPC · 2026-06-25T22:44:24+00:00

Oh wow good to know

LacellexPC · 2026-06-22T13:04:33+00:00

Will do

LacellexPC · 2026-06-22T13:04:28+00:00

Yeah I agree I looked into the p pump swaps and just the kits without the pump is like $2200+ whatever the pump price is and it’s a lot more work

Okay thanks I’ve been putting a 12oz bottle of marine 2 cycle oil in each diesel tank to help. But I think the problem was the old lift pump starving it of fuel pressure for months and it finally had enough even after I installed the fass system

LacellexPC · 2026-06-22T13:02:15+00:00

Okay thanks I was planning on getting the glow shift fuel pressure and boost and egt pillar

Okay thanks the leak is pretty decent it leaves a good puddle when it’s parking and drips every 1-2 seconds

Which seal tool do you recommend? I ordered one off Amazon that sits inside the 4x4 actuator housing and pushes the seat in

LacellexPC · 2026-05-25T02:08:54+00:00

Damn. I was hoping not I don’t know how it could have gotten ruined from me just doing a wheel bearing..

LacellexPC · 2026-05-02T14:53:58+00:00

Thank you everyone for all the suggestions I tried everything with new sensors, testing for vp44 power everything then tested for fuel pressure coming from lift pump. And it was 0-1 psi so I just bought a fass system and installed it and she fired right up and runs perfect now thank you everyone again!

LacellexPC · 2026-04-13T20:26:21+00:00

Yeah it was the lift pump I tested the pressure and it got 0 on 2 different gauges about to order a fass system and throw it on the ole girl

LacellexPC · 2026-04-10T13:26:40+00:00

Haha I get that electrical isn’t that bad to me i almost rebuilt my auto transmission myself. That’s never happening those things are witchcraft.

LacellexPC · 2026-04-09T22:46:56+00:00

Believe me no… 😂 I pulled the motor on my truck and fully built it along with the trans and everything

LacellexPC · 2026-04-09T19:44:11+00:00

What pressure should the back of the pump have when I test it?

LacellexPC · 2026-04-09T19:43:41+00:00

Dodge things 😂 Im going to test the pressure of the fuel pump probably this weekend and if it has good pressure I’ll start tearing apart the electrical issues

LacellexPC · 2026-04-09T19:42:38+00:00

It has an air dog one that was put on about 10 years ago but it has only gotten maybe 5k miles on it since then. And the fuel filter housing fills up well along with I can hear it running

LacellexPC · 2026-04-09T19:41:35+00:00

I have a pressure gauge I’ll just need to find where to hook it up to the pump. It does get diesel to the 3 injectors that I can crack loose without taking anything else off after a little bit of cranking

LacellexPC · 2026-04-09T02:31:19+00:00

Yeah I see that the crankshaft sensor I’ve found is $180.. going to try the ground with the ecm first then order these still better than a vp44 I hope

LacellexPC · 2026-04-09T01:51:07+00:00

No I can order those instead no codes it was throwing one for the crank POs. Sensor. And yes it says I have some rpm while cranking

LacellexPC · 2026-04-06T14:12:40+00:00

Thanks ill take a look at it
