Help please for the second time. Yesterday I was driving and I noticed that the truck did not want to jump to over drive so I was thinking that it was the brake switch like many you have told me so I was hitting the brake peddle and nothing. well I shut it off like before and I don’t know if it worked or not because we were in town for a while but then I was about to get on the interstate and I floored it and then it shut off nothing I pulled over and it would not start it would crank and turn over but nothing, we (my friends and I) could never hear the pump kick in. I checked the fuses they all seemed good. So my question what could it be? How can I find out if it is the pump has anybody dealt with something like this?

When my 01 lift pump went out it was sputtering then died and would not start. My 02 is out of state and I am waiting to hear from the repair shop this morning, I was driving down the interstate and it just shut off as you describe yours did. They said they would call before noon to let me know what the problem is. I will post that info.

Just talked with them, they haven't looked at it yet, calling them back at 4pm

thanks man I am about to go out and check mine. let me know what they say about yours. My dad said it might be something got unpluged I doubt it but hey its worth a shot huh? on yours did you just floor it or something?

My 01 was the lift pump which the local Cummins dealer changed out. My 02 has the converted fuel pump in the tank so I don't know what that is going to be.
The 02 I was passing a vehicle going up a slight grade under full acceleration then "pow" loss of power, RPM's dropped to 1200 then engine died.

To still be running a 24 valve without a fuel pressure gauge should be a criminal offense.

Check your fuel pressure from the output side of the filter, and that will narrow down the problem.

TexMexCowboy

ok this might sound dumb to you but since this is my first diesel and i am a rookie at this. How do you check the pressure? and you are saying that I should put a fuel pressure gauge on my truck? what else do you recomend I am just learning all this stuff so i wouldnt mind the help?

Know where the Injection pump is?
theres a scrader valve (like a tire valve) on the in line.
You can get a pressure guage at Kragen,needs to have pressure there.
Better yet install a pressure guage.

Just got off the phone with them. The power wire from the battery to the in tank fuel pump was loose. They are replacing the battery ends and that wire, will be ready tomorrow at noon.

One quick question on fuel gauges, will a 1-15 PSI be enough or do I need a 1-30 PSI?

phox_mulder

30psi guage would be best, then normal pressure will be right in the middle.

15psi guage would be pegged all the time with a good lift pump.

If i were to put a fuel guage on where do i hook it up is it electrical or how do they work. I checked the pressure there was none. Tomorrow i am going to take it to the dealer ship ill see what they tell me.

Heres my FP guage setup, just to give you an idea.



Heres where it taps for the pressure reading, right at the VP44 inlet.

TexMexCowboy

nice setup I am going to look in to doing that also to mine. what other guages do you recomend me putting on this truck?
