Fuel pump quits after the engine runs for a while

Did you check the asd relay ? Does the fuel pump run if you jumper the pump relay ?
Does the engine have normal compression, spark, and fuel pressure ?

What you are telling me is the engine is firing the plugs but not getting fuel.
When you changed the fuel pump and filter, did you check the fuel pressure at the rail ?
Are the injectors getting power and ground pulse ??

Before starting the engine, the fuel pump should only run for a few seconds when the key is first turned, to pressurize the fuel system. Even though the pump appears to be running, you may either have not enough or too much pressure for the engine to keep running (fuel pump or pressure regulator). I think it may just be a coincidence the engine quit while turning a corner, but the gas in your tank may have been so low it sloshed away from what is likely a very old pump, starving it and causing it to failure.

sounds like you need to check your fuel pump relay

Gauge fuse runs a fuel module that is installed to correct vapor lock. This module is what is running the pump. This module, called the hot fuel module is mounted on the passenger side behind the dash above the blower motor.

reset the alarn/immobiliser.........

The engines oil pressure switch has a third wire which is connected to the fuel pump. The oil pressure gauge may work although the third wire to the pump may be at fault causing your delimma
Once the engines oil pressure reached the normal operating range the computer shuts down the oil switches third wire to the pump and the relay takes over until you shut the emgine off

when replacing fuel pumps on alot of chevys its recommended to replace the harness also or you can have repeated fuel pump failures. Do a search on,, why repeat fuel pump failures;; and you'l have some info to go on.

If your filter hasn't been changed recently then by all means do itand see if that helps. I change mine twice a year, spring and fall. You are probably right about the fuel pump but your best bet would be to pick up a copy of Haynes Diesel Engine Repair Manual, part #10330 first. It has an excellent diagnostic and repair section as well as testing procedures and repairs for these engines. It costs about $20 and could save you some money. Hope this helps.

check the fuse and relay for the fuel pump in the engine compartment fuse box near the battery... as well as the fuel shut off switch in the back (trunk) part of the vehicle
