Be sure you are getting good fire to the plugs and if you are take a spray bottle and spray fuel into the tbi and if it runs ok then you have a fuel problem, your pressure regulator in the tbi could be week and not putting enough fuel to the tbi. If not you need to pull the o2 sensor out ahead of the catalytic converter and see if it runs ok if it does then you either have a plugged cat or muffler. To much back pressure on the engine will not allow it to draw fuel into the cylinders and fire the fuel. Hope this helps.

Hello Johnholley
I am wondering do you hear the fuel pump when you just turn the key into the on run position not crank just in run and listen and see if you hear the fuel pump run for a second, If you don't hear it you will want to check for power at the fuel tank, and have some one cycle the key while your under the truck with a test light. Hopefully you have power and you hear the fuel pump run. Now if you do hear the fuel pump running then the next thing you will want to check is for spark, It could be the ignition module or pickup coil. check out those thing and I am sure you will be able to figure out whats going on. If you don't get back to me and we can try a few other methods. I sure hope that helps you out johnholley. and thanks for using Fix Ya Bear001

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 should be close to 5000 lbs

if your gauge was working prior to the replacement, then I'd suspect a loose electrical connection. There should be 2 plugs going to the fuel pump module (pump + sender are one piece unit) in the fuel tank. One for the pump, naturally the other for the gauge (two wire socket). If connections are tight, you may have a faulty pump module,or the installer may have damaged the sender upon replacement. I hope this helps.

Chevy Trucks, Blazers, S10 pickup and the like will vapor lock ecspecially the 2000 models. Do not tighten the gas cap past 1 click. There is a tube that runs from the top of the tank down and this gets hot and collapses or burns in half. We just bought a reinforced rubber tube cut it to lengh and use it instead of part and it's worked grat for 2 years so far.

Why does it continue to spit and sputter going uphill?

Spit and sputter can happen because of not enough fuel or air. last thing to check for fuel is the fuel pressure regulator. On the air side would be the the air filter(filthy) or catalytic converters(clogged). on the mechanical side, Could be bad rings, burnt valves. Compression test would find this.

Hello, I have a 99 silverado z71, I was driving along and all of the sudden it lost power and started to spit and sputter and ended up on the side of the road,sitting there it continued to idle roughly,...

Have the shop check fuel pressure at the fuel rail. Maybe the pump impeller has failed. If fuel pressure is good, your timing chain/belt may have slipped.

Pickup died while driving it

You need to put a fuel pressure tester in the fuel rail and then determine weather or not you need the fuel pump replaced,if this is not the case then the throttle position sensor is likely the culprit.

Truck was running fine , it started to spuder then died , ichanged the fuel filter & now it wont start

You have to make sure all of the air is bled out of the fuel line. start with top of fuel filter then injector pump. If it still won't run then loosen an injector pipe until it stops spitting air. It is possible that the original reason that it sputtered and stopped could be air getting sucked into the fuel line...hope this helps.

Our truck died while driving down the road we replaced the fuel pump and now the truck starts and runs but its really sluggish and sputters alot

that may be caused by a plugged fuel filter or fuel line, you need too replace the filter when you replace the pump.............
