2010 Chevrolet Express 6.0L 2500 LT need to know how to replace fuel pump.

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

SOURCE: turns over but won't start

I'll tell ya what a diesel mechanic told me..."fuel injector pump". It seems that the new low sulfur diesel being sold now wears the seals out on the older pumps. I changed the fuel sending unit and that seemed to help a little, but now while driving it will shut down, and it's hard to start. Going to have the job done now. Part is very expensive! Hope this helps.

SOURCE: how to replace a oil pump

Probably a 3 out of 5 on my diy difficulty scale, here goes: 1 remove negative battery cable 2 raise and support the van on jack stands 3 remove the motor mount bolts from both sides( do not worry the engine will not fall on you) 4 remove the oil pan retaining bolts 5 unplug oil level sensor if equipped 6 bump oil pan with a RUBBER mallet to break the gasket seal 7 remove oil pan, you might have to raise the engine with a jack placed under the front pulley, use a block of wood to avoid marring the pulley, and raise the engine just enough to allow the oil pan to slip out. 8 remove the oil pump retaining bolt and allow the pump to come straight down. 9 you will have to re use the intermediate shaft, the collar that holds it on will most likely break when you try to remove it, you can get a new one, it will probably come with the new oil pump. You can reuse the oil pump pickup tube, but it is cheap insurance to replace it. reassemble in reverse order, pay attention to the oil pan gasket, be careful and get the corners in correctly, extra time spent here will prevent a leak later.

SOURCE: no power to fuel pump

2002 Avalanche Thought the fuel pump was bad change pump still no power to pump?

SOURCE: Why is my 2004 Lincoln Navigator missing or choking out with

It could be the filter agian; it could be the fuel pump, or it could simply be either a vacuum leak, EGR valve, fuel pump relay, O2 (oxygen) sensor(s), plugged injector (carburated, fuel injected); fuel pressure regulator, hole in a fuel line (look for fuel leaks under engine, and along side the driver side of car (under car).
I suggest having a fuel pressure test performed, and having the vacuum system tested, which should include EGR valve. Another possibilty, simply; could be the air filter. If it is ripped, torn, full of dirt and debris (from driving), it is possible it is clogged and is preventing sufficient air flow to the intake which will cause the car to hesitate, stall, idle roughly, or even die when accelerator pressure is released, or braking is applied. My 93 Subaru had this vary issue when I purchased it, and when upon checking the air filter, it looked as though rats or mice had begun digging (chewing) at the air filter. It was so torn that the filter was starting to get sucked up toward the intake which was plugging the air vent (hose), causing a lack of proper air intake (this mixes with the the fuel). Improper air/fuel mixture will cause a car to not even start, or stay running for a few seconds.
You can determine the fuel pump by having someone kneel down by the back of the car while you turn the ignition to the "on" position - DO NOT START the car -- when the ignition is turned to the "on" position, the fuel pump is actuated to draw fuel to the engine (this is a "primer" method"). If the person can hear the pump engage, then the pump is good. To ensure fuel pressure, after the car has sat for about an hour or so, locate the fuel rail (chrome, silver usually, sometimes black) and find the black screw port (usually black) and remove it. Carefully (cover with hand or rag etc) and depress the needle inside the port; if fuel sprays out (won't be too too much) then you have fuel pressure. If no fuel comes out, then move on to having the fuel pressure regulator and fuel pump relay replaced. Even if these are good, (no way to tell) - these being replaced will eliminate them as possible culprits.


The O2 sensors can be detected as a possible issue by having a diagnostics test performed (free usually at participating auto parts dealers; Napa, Baxter's, etc) *States, auto parts dealers vary.
