Question about 2001 Chevrolet Silverado 2500HD

Open Question

01 Chevrolet Silverado 2500HD Diesel

I have a error code of P0093a that shows up which means large leak. The truck looses power and will only maintain 65 MPH. From stop I have to push the gas just a little until the gear changes then I can push the gas some more until the next gear changes and so on. The service light comes on and stays on and I have to pull over and cut the truck off for about 5 min. Then I can turn the truck back on and I've got power until it happens again. Once I've turned the truck off for several hours the service light will go off as if there never was a problem. I've hade the truck at the dealer and they have replaced the Primer, all the fuel lines to the fuel tank, the fuel sensor, a transmision sensor, and the injectors on the drivers side. I have a feeling it might be the fuel pump and sending unit but no one seems to know. Would appreciate any help.

SOURCE: Chevrolet 2500 Not Running, May Be Fuel Filter Sensor

That red wire is only for the fuel heater.will not cause a no start.try pumping the primer pump on top of the fuel flter hsg. but first open the bleed screw,which is black plastic also located on the top.this will eliminate any trapped air that might have entered the fuel intake system.if the pump does not get firmer and harder to push, then you have a leak in the fuel supply lines or the ck valves in the fuel filter hsg or stuck open. Still no start have it scanned to ck fuel pressure while cranking.it should be close to 5000 lbs

you can pull the boat no problem. as putting in a 6.2 for the 454 you will need to change wire harness inside and out..im the brake booster...... the gear ratio in the rear ends ..fuel pump ..im guessing you have a truck you will be using for parts.. if you are doing for fuel mileage you will be disappointed you will only gain a couple of mpg .. hopes this helps

I would check the connection at the back of the instrument panel. And check the connector at the Vehicle Speed Sensor. The vehicle speed sensor should be located at the rear of the trans or transfer case. This is a two wire connector.

SOURCE: Fuel Sending unit on a 2000 Chevy Silverado

if it is the fuel level sending unit you will have to replace the pump because they are a 1 piece assambly. it will be a task to change too as you will need to either remove the truck bed or drop the fuel tank to get to it.

Duramax diesel Silverado 2500HD 2001 is throwing code P0093.....Can anyone tell us what to do to fix it?


Very odd. A Google search comes back with lots of "Duramax" hits . The code is: "Fuel System Leak Detected - Large Leak"
Some fixes that I found were replacing the fuel filter, others changed the FPRV (Fuel pump return valve?)
When you're pulling a trailer there is a much greater load (air resistance) even when just cruising. Empty or fully loaded, it's mass won't matter, it's the extra fuel required at every phase of your drive. If the fuel filter is getting clogged, it's possible that some sensor is showing a pressure that is beyond predetermined limits. Try the fuel filter replacement first to see if that fixes it.

mcdevito75 here, The fuel pump should be in the gas tank. Change the fiel filter before condming the fuel pump. You may also have to drain a little water out of the gas tank. Your local repair shop can check this out.

I have a PO402 code show up,recirculation flow excessive detected, what can be done to make the lite go off


You have a 6.6 diesel correct? check for leaks between the air cleaner and the turbo. If you can't find any you may have a sticking egr valve. If you just want to clear the code, try disconnecting the battery for a few minutes.

What could cause the engine to fill itself with diesel?


The injectors are leaking. G.M. had alot of problems with leaking injectors. Not real sure but it might have been a recall. You can ask G.M. dealership if it was a recall.
