Chevrolet 2500 Not Running, May Be Fuel Filter Sensor

Need help starting my 2002 Chevrolet 2500? Duramax Diesel 2002 Chevrolet 2500 Started the truck this morning, ran for two minutes then died. Has power, turns over and is not giving me any computer codes. No dead fuses either. A red wire ontop the fuel filter had come undone so I plugged back in. Still won't run. I primed the and drained the fuel filter a couple times and it is getting fuel. I have a feeling that the truck won't run because of something to do with the Fuel Filter sensor, an ideas?

    i have a similar problem with a 2002 silverado hd 8.1 l gas engine. truck started sputtering and died , first thought of bad gas but ruled that out when other gas powered motors seem to run fine on same fuel, so pulled fuel pump , it seems to work fine.. what i need to know now is what is the fuel pressure suppose to be >??? and any ideas of what else could cause this? where can one find a service manual or on line manual that will help? thanks for any info or past experiences,.,,,

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

2005 Duramax stopped running.replaced fuel filter and sensor,no luck cam you help.


After replacing the fuel filter did you prime the system? There should be a small circular pump on top of the filter assembly to prime it. I own a 2003 Duramax and it usually takes about 5 pumps / turn over / 5 more pumps / turn over / and 5 more and you should get it started. It will take longer if you didn't fill the fuel filter with diesel before installing it as well. Let me know. Thanks.

2002 chevy 6.6 duramax wont start even in warm weather or after motor is warm..... only starts with starting fluid. codes are p0335/p0193/poo87/p0090


The Duramax fuel filter assembly is bad about sucking air. Replace the fuel filter assembly. It comes with a new fuel filter.
I need some good feedback.

My 2500 duramax diesel dosent want to start


Does it have diesel?
Could be fuel filter or fuel pump.
Glow plugs?
Injectors? these trucks have been known to have bad injectors.
Possibly the oil pump, the injectors run off the oil pump.

2002 duramax diesel that seems to be starving for fuel. replaced the fuel filter and no help. The fuel lines are colapsing at the fuel filter.


try to replace the fuel pump. possibly cause might be you replaced your filter a little to late, that some dirt already entered your pump. also, try to clean the fuel lines itself.

2002 chev. duramax starts fine when temp. out side


whens the last time you changed the fuel filter? ther maybe to much water in the filter and the tank, on warmer days the fuel maybe trying to seprate in the filter, when you go to start it you maybe trying to run it on water more then diesel. add a cetien booster to the tank of fuel you have see if that helps

2004 chev 2500 duramax diesel no start and no fuel pressure


primay fuel pump is defective and won't allow the secondary pump to build pressure and causes it to die and has lack of power, most likely it started getting gutless before it happened.
