Check the psi reading on the fuel pressure tester - this is known as the idling pressure - and compare it to the recommended pressure in the repair manual. If it is even a few pounds low, there is a problem in the fuel system, such as: weak fuel pump, low fuel pump voltage, clogged fuel filter or bad pressure regulator. Quickly test the fuel pump pressure on most injector systems with this fuel injection pump tester. The tester’s gauge reads 0-100 PSI, 0 to 7 bar. The fuel injection pump tester comes with flex hoses, fittings and instructions for quick reference. The tester fits most systems, except for Bosch, CIS-Jetronic, and GM throttle body systems. ATD-5657 Deluxe Vacuum and Fuel Pump Tester Owner’s Manual Complete with 2 ft. Of high quality hose, plus (3) fittings to test domestic and foreign cars and trucks with gasoline engines 3-1/2' compound gauge has a multicolor dual scale dial with ranges from 0–10 psi, 0–0.7kg/cm2 pressure and 0–28inHg/0-70cmHg vacuum.
HomeAuto RepairHow to Test a Fuel Pump on a 2001 Chevrolet Blazer
The heart of a 2001 Chevrolet Blazer’s fuel system is the electric fuel pump mounted internally in the fuel tank. The fuel system on the Blazer is quite sophisticated, which makes troubleshooting a tricky process. The power supply to the fuel pump is computer operated and routed through several fuse blocks and a fuel pump relay. When fuel system issues arise one of the first potential causes to eliminate is the fuel filter. You do this by replacing it. The filter is located under the Blazer near the driver’s side frame rail between the fuel tank and the engine compartment.
If a car stops and has not run out of petrol, check whether there is petrol in the carburettor. If there is not, there is a fault in the fuel system. A mechanical-pump drive hardly ever fails — though signs of wear may appear on the cam and operating lever, linkages and pins. Diaphragms can leak. 4.4 Fuel Pump Troubleshooting 4.5 Carburetor Troubleshooting The fuel pump transfers fuel from a source to the This section is for fuel-related problems only. Use for carburetor.

Test a Fuel Pump
Spray a small amount of starting fluid into the Chevrolet Blazer’s air cleaner while cranking the starter. If the Blazer starts up momentarily and stalls a few seconds after the starting fluid dissipates it indicates a fuel problem.
HomeAuto RepairHow to Test a Fuel Pump on a 1999 Ford Mustang
The fuel system in the 1999 Ford Mustang is a return-less system that uses a fuel pump module to supply and modulate power to the pump and vary the speed at which the pump runs. Testing the fuel pump in this Mustang is similar to testing older Mustangs, with the exception of adding a fuel pressure regulator test. The average home mechanic can test this system in a few minutes.

Place wedge-shaped wheel chocks behind and in front of the front wheels of the Mustang. Kick the wheel chocks with your heel to force them securely against the tire, preventing the car from rolling. Raise the rear wheels of the car off the ground using a floor jack placed under the center of the (differential) housing in the rear of the car. Place jack stands under both rear axle tubes that connect the rear wheels to the differential. Lower the jack until the axle tubes are resting on the stands.
Fuel Pressure Tester
Attach the battery clips on the automotive circuit tester to the Mustang’s battery located in the driver-side front of the engine compartment. To do this, squeeze the insulated portion of the clip to spread its spring loaded metal jaws and slip the open jaws over the battery terminal. Release the clip.
