truck wont start
I have an 06 lbz with 85k on the odometer.I have exaust and air cleaner on it otherwise all stock. I used to run a edge on it but removed it a year ago.
we were pulling the trailer on flat ground yesterday about 15k lbs when it went into limp mode setting off a Poo87 code ,purchased code reader from autozone. Cleared the code a few times ,and now the truck has died completely and wont start. I am home now after a 100 mile tow with my fifth wheel . I changed fuel filter and oil about 4500 miles ago.I am going to try a new filter this morning. the truck was running fine until this happened. thanks Derek

could be a collapsed fuel line. There is a tsb on that. May be worth looking into if the filter does not fix.

Pump the primer on the filter housing--the housing seals dry out from the excessive heat in the engine compartment, and then sucks air, not fuel.
The seal kit is available from many Forum supporting vendors. GM only sells a new filter housing. Good idea to replace the filter-- cut the old filter open and inspect for water-dirt.

Is your primer bulb staying hard or does it get soft after sitting overnight? P0087 means your starving for fuel, either by allowing in air through seals, or leaks, could be a collapsed fuel line, could be the pickup tube in the tank is plugged up, and it could be the FPRV is stuck open not allowing the rails to hold pressure. Was your old filter full of fuel? How many pumps did it take to fill the new filter? Is the pump bulb firm? Check the schrader valve located under the black plastic cap on the fuel line passenger side front, is there fuel around the valve and if so are there bubbles forming around it? If so it is leaking. Do you have a lift pump installed in the fuel system? The P0087 code is a popular headache but can be diagnosed and resolved.

the primer bulb goes soft after a few minutes, the old filter was full, and the new took a few pumps to fill,i checked the schrader valve and it sprayed fuel when depressed. I do not have a lift pump.When it occurred it first went to limp then shut off while driving and have never been able to start it since.

You have an air leak, now you just need to find it. Couple common areas are the seal kit JC recommended, but two big culprits are the bleeder screw on top of the filter housing and the water sensor / drain that screws into the filter itself. Those crack and leak often. $50 for the sensor and $12 for the screw, those would be my two first guesses.
