How to test the voltage of the ignition switch?
Method 1: Using a Test Light 1 Turn the ignition switch off and disconnect the module’s wire. 2 Find the starter solenoid’s S terminal and disengage it. 3 Rotate the ignition key and place it on the run status. 4 Probe your ignition red wire connection to test the voltage. 5 Test the ignition coil’s battery in the same way.

What happens when the ignition switch goes out of order?
Just after inserting the key, you’ll see the switch at the off status. After turning it a bit, you’ll reach the on position. Here you’ll see the dashboard lighting while keeping the engine off. If your ignition switch goes out of order, then your lights will remain off at the second position.

How to test the performance of a fuel pump?
Now start the engine so we can test the performance of the pump. While the engine is running, the fuel pressure should drop about 5 psi, from the static prime pressure (DPI) then snap the throttle, the fuel system pressure should jump up about 5 psi. this means the fuel pump and pressure regulator is working correctly.
How do you test fuel pressure on a car?
Remove the fuel pressure test gauge from the kit. Most gauges have a quick disconnect coupler that will allow several different adaptors for various manufacturers. The kit should have them labeled but if not look for the hose connector or fitting that will work for your car.
What to do if there is no pressure on the fuel pump?
If no pressure is present recheck the hose or adapter connection to avoid any false negatives, re-cycle the ignition switch to recheck. Still no pressure? suspect a bad fuel pump, fuel pump relay or fuse. Now start the engine so we can test the performance of the pump.
How does a fuel pressure tester work in a car?
Checking an ignition tester can easily verify ignition operation, and a fuel pressure tester is nearly as easy to operate. The simple design consists of a gauge attached to a fuel hose and multiple fittings.
What are the symptoms of a bad fuel pressure regulator?
The symptoms are very noticeable, too. You may notice a very rough idle, rough acceleration, slow acceleration, and vibrations from the engine. There are also many causes of engine misfires. It can be a problem in the spark plug or the ignition coil.
Where is the fuel gauge on a car?
The fuel pressure test port is on the fuel rail on the drivers side of the engine. Simply attach the fuel pressure gauge to the fuel rail and turn the key on (you can start the engine if it runs) to take a fuel pressure reading.
What do I need to check fuel pressure?
You would measure current in Amps. You will need either a voltmeter that has an amp setting or a voltmeter that works with an amp clamp or a lab scope. I like using a Fluke 87 with an amp clamp for this job. It is a fantastic and extremely reliable voltmeter. Just clamp around the power wire going to the pump itself and start the vehicle.
