    Q:
    How to check fuel pump and fuel pressure on Chevrolet Astro? Posted by Customer
    A:
    Certain precautions should be taken when it comes to fuel system maintenance. The first step involves relieving the fuel pressure, and in order to prevent fuel leakage, a shop towel should be placed over any fuel line connections that need to be disconnected. Before starting the engine, check for fuel in the tank and look for leaks or blockages in the fuel lines, hoses and connectors. A pressure gauge with an adapter set is used in conducting a fuel pressure check on carbureted and TBI engines. Next, remove this line from throttle body for carbureted and TBI engines or replace it with a Schrader valve on the fuel supply line for CMFI and CSFI engines. Afterward, start the engine depending on your engine type to find out about your fuel pressure. Perform a Fuel Pump Volume Check if Pressure is Too low; otherwise inspect for Fuel Line Restrictions if volume is insufficient. Replace the pump if there are no restrictions found. Similarly, there are some things that can be done during an electrical circuit test of TBI, CMFI and CSFI engines such as checking power at the relay of a fuel pump and power present at the connector of a fuel pump. If there is no power, then consider wiring problems or a bad relay. Pull out oil pressure switch take out resistance facing down into its hole while running engine; if engine dies out then oil pressure switch or its wire may had gone wrong.

    Q:
    How to check the Fuel Pump on Chevrolet C1500? Posted by Customer
    A:
    If there is suspected insufficient fuel delivery, start by inspecting all fuel lines for leaks. Have an assistant turn the ignition switch to the ON position while listening for the fuel pump's "whirring" sound. If no sound is heard, check the fuel pump relay, fuses, and wiring. If power is present at the fuel pump connector and it still doesn't operate, replace the fuel pump. For the pressure check, use a fuel pressure gauge with the appropriate fittings. Relieve fuel pressure and install the gauge. Turn the ignition key On to observe the pressure reading, comparing it to the specified value. If the pressure is low, check for restrictions in fuel lines and filters, and inspect the fuel pump for issues. If the pressure is high, inspect the fuel return line for restrictions and replace the fuel pressure regulator if necessary. Start the engine and ensure the pressure is 3 to 10 psi below the previous reading. Monitor the pressure for five minutes after shutting off the engine; if it drops significantly, there might be a leak in the fuel line or injectors, or a defective fuel pump module check valve.

    Q:
    How is the fuel pump/sending unit assembly removed from the fuel tank for the 1997 Chevrolet K1500? Posted by Customer
    A:
    First, relieve the fuel pressure and remove the fuel tank. The fuel pump/sending unit assembly is located inside the fuel tank and is held in place by a cam lockring mechanism. To unlock the assembly, turn the lockring counterclockwise with a hammer and a brass punch. It's important not to use a steel punch to avoid sparking and the risk of an explosion. Carefully extract the fuel pump/sending unit assembly from the tank, taking care not to bump the fuel level float and sending unit into the lockring during removal to avoid affecting the accuracy of the sending unit.
