Question about 2001 Chevrolet Silverado 2500HD
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.

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

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

if it dont have good compression it will not start check the comp and make sure there no water in oil if fuel pressure is low it will not pop the injector open try some starting fluid

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.

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.
