How to check the fuel pump output and pressure for Chevrolet Blazer,S10,GMC Jimmy and Sonoma?

To check the fuel pump output and pressure, relieve the fuel pressure. Next, Install a fuel pressure gauge on the fuel rail, location varies depending on the system. Turn the ignition switch on without starting the engine and note the reading on the gauge as the fuel pump runs for about two seconds. The pressure should hold steady within the specified range. Start the engine and let it idle at normal operating temperature, with the pressure expected to be lower by 3 to 10 psi. If the pressure does not drop as expected, apply a vacuum to the pressure regulator and if it drops, repair the vacuum source or replace the regulator. If the pressure is not within specifications, check for a vacuum to the regulator or a pinched/clogged fuel return hose. If the pressure is still low, change the fuel filter and if it remains low, install a fuel line shut-off adapter to test the regulator. If the pressure is still low with the return line restricted, there may be a leaking injector or a faulty fuel pump. To check the fuel pump's electrical circuits, verify that the pump runs by listening for a whirring noise when the ignition switch is turned on and when the engine is started.

How do you remove the fuel pump/sending unit assembly on Chevrolet Blazer,S10,GMC Jimmy and Sonoma?

Start by relieving fuel system pressure and detach the cable from the negative battery lead to remove the fuel pump/sending unit assembly. Afterwards, remove the fuel tank and gently tap on the locking cam until tabs co-align with recesses that will release the assembly. Lift it out of its place in the tank, moving any necessary components over to a new fuel pump module assembly. For models produced 1995 or earlier, eliminate strainer from bottom part of fuel pump and clean/replace if needed. Unplug electrical connector and disengage fuel pump from assembly. To install, reassemble the sending unit bracket assembly back onto the fuel pump as well as insert an assembly into a gas tank and finally put back all parts of fuel tank.

Chevrolet Blazer Fuel Pump

Chevrolet Blazer Fuel Pump is a component in the vehicle which pumps the fuel from the tank to the carburetor or the system of fuel injection. Some of the popular fuel pumps include electric fuel pump for injection systems and mechanical fuel pump for carburetor systems and Blazer models use these pumps. Mechanical pumps are driven by the camshaft and produce less pressure and on the other hand, electric ones produce more pressure and are controlled by the ECUs for proper fueling. Switching from a conventional pump may improve the engines' performance when it comes to fuel quantity and delivery, suitable for high horsepower engines. So, to avoid such problems as engine jerking, power loss, or even inability to driving uphill, one should check it constantly and replace when needed in Chevrolet Blazer.

Each OEM Chevrolet Blazer Fuel Pump we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
