You should also keep in mind that there could be inaccuracies in your test result. We do not fully recommend this but if the situation is urgent, then you carefully can try it for both high and low fuel pump pressure. However, there is the risk of unexpected ignition as the material in the gauge is very much compatible with gasoline. Indeed, you can check your fuel pump pressure without a pressure gauge.

How To Check Fuel Pump Pressure Without A Pressure Gauge In this way, you would be able to test your fuel pump without a fuel pressure gauge. Conclusively, make sure that the fuel is flowing, while the pump is working. Usually, the fan relay wire should be on the left. However, it is necessary that you are able to distinguish which wire is which by tracing them. This fuel pump relay will resemble the fan relay. Thereafter, all you have to do is test the fuel pump by disconnecting the rubber supply line and then jumping the fuel pump relay. You would need to connect it along with the oil pressure sending unit for the dash gauge. You will find a two-wire oil pursuit switch at the back of the distributor fitted off the brass fitting that is screwed into the china wall. For this test, you may need the ECM used to harness the control of the pump. However, we will be explaining to you how you can test your fuel pump even without a pressure gauge. To some people, it may sound absurd and most likely impossible. There may be absolutely no reason to test a fuel pump without a pressure gauge. How To Test A Fuel Pump Without A Pressure Gauge If you lift the rear seat bottoms, you may have a chance of listening to it closely.

If the test works well, then you would be able to hear the sound of the fuel pump running even from inside your car provided your windows are up. However, if there is a problem with your FP or you have a bad wiring, the pump would most likely not run. If there is nothing wrong with your CPS, ECU and FP relay, then you should notice the +12V. The aim is to provide 12 volts directly to the pump and totally bypass the normal process of the ECU receiving the signal from the CPS for FP to function. All you have to do is check for +12 volts between the top of fuse 32. However, you can test your car fuel pump with battery even after installing it. It is more or less the way of testing your car fuel pump before installing it. Testing fuel pump with battery is actually possible and a recommendable idea.

Here, you have to observe the continuity of the connector and motor windings as you use it. You can test a fuel pump before installing it by using a multimeter. We still recommend using the first option of hooking 12 volts and seeing if the car would run. However, we strongly caution you to be very careful as gas is highly volatile and could cause severe damage. You would then have to hook up a gauge so as to observe the amount of pressure being produced, or you could as well simply aim the hose back into the container, if you only want to see it pump gas. On other hand, you could just test it by getting a container of gas, hooking up the hose and dropping the pump into the container.

One of the ways by which you can test a fuel pump before you proceed to install it is by attaching 12 volts to it. read also on fuel cap check engine light How To Test A Fuel Pump Before Installing It You would also be learning different ways you can test a fuel pump.
