There are testing procedures for relays and ohm readings but it differs for all makes. The easiest way is to swap out an identical relay on the vehicle and check to see if the pump comes on. I know that on Ford Rangers there are 3 that are the same ECC, fuel pump, and AC. Since I knew that the ac worked I moved the relay over to the fuel pump and got no response still, so I moved it over to the ECC and both it and the fuel pump worked so that told me that the ecc relay was bad and it in turn triggered the fuel pump relay to activate in series.
What else can I help you with?
Does a fuel pump relay change the voltage to a fuel pump?
No, the fuel pump relay engages and sends voltage to the fuel pump. The fuel pump requires 12 V DC to operate properly. A fuel pressure test will verify the condition of the fuel pump.
What do you check before replacing fuel pump in a 1997 explorer?
Fuel Pump fuse, relay, fuel filter, and all connections.

How do you test the fuel pump relay on a 92 dodge shadow?
I believe that you can switch the Horn Relay with the Fuel Pump Relay and if the horn no longer works and the Fuel Pump does then that relay went bad... try that, its a sure fire way to know whats wrong... If it checks out good it might be a Defective Fuel Pump.
Does the fuel pump relay send power to the fuel pump driver module?
Yes, the fuel pump relay turns on and off sending power to the fuel pump as needed. The best to test that relay is to just replace it with a new one. Also make sure and check the fuel pump fuse and replace the fuel filter as it might be clogged.
How can you test a 1986 Volvo 240 dl fuel pump relay?
To test a 1986 Volvo 240 DL fuel pump relay, first locate the relay in the fuse box. Use a multimeter to check for continuity by applying power to the relay terminals while listening for a click, indicating it's functioning. Additionally, you can bypass the relay by connecting the fuel pump directly to the battery to see if the pump operates. If the pump runs with the bypass but not with the relay, the relay is likely faulty.
How do you test the fuel pump relay - Mercedes 190e?
To test the fuel pump relay in a Mercedes 190E, first locate the relay in the fuse box. Use a multimeter to check for continuity by connecting the probes to the relay terminals; it should show continuity when energized. Alternatively, you can swap the relay with a similar one in the box to see if the fuel pump operates. If there's still no fuel delivery, the issue may lie elsewhere in the fuel system.
How do test the fuel pump relay to see if it's bad in a 1996 Chevy Suburban?
pull the fuel pump relay and put it in another location that uses the same relay...like the A/C relay.
How can you test the pump if not working?
If the fuse & fuel pump relay are good then more than likely the pump is bad.
How do you bypass a relay to test the fuel pump in a 1989 Toyota cressida?
Turn key on-jumper relay receptacle pin 1 and 3 this will cause the fuel pump to come on-
Does the 2005 pt crusier have a fuel pump relay?
A 2005 PT Cruiser does have a fuel pump relay. They have a fuel pump relay rather than a fuel pump switch. The fuel pump relay is located in the fuse box.
