Proof the fuel pump relay on your Hyundai Excel.
Competency advantage to the fuel pump on your Hyundai Excel is handled by the authority relay or switch. This relay besides supplies bent to the injectors and the electronic polity unit (ECU) or pc. Adore any other electro-mechanical relays, this direction switch contains movable points and coils that may burn or tear. To confirm that the fuel pump relay on your Hyundai pattern is the agency of the hitch, countdown it and alter it whether compulsory.
Instructions
1. Name the curb/pump relay terminals. Whether you fix the relay with the terminals facing you and the lock tab pointing up, these would be the terminal identification numbers. Top row, from left to fitting: 4, 3, 2 and 1. Lower row, from left to genuine: 8, 7, 6 and 5.
Your ohmmeter should indicate a reading of 0 ohms.9. Hook up the ohmmeter leads to relay terminals 1 and 2.
Hook up the ohmmeter leads to relay terminals 1 and 4. You should predispose an infinity reading or no conductivity.
4. Hook up the ohmmeter leads to relay terminals 2 and 8. Your metre should present a reading price hurried to 95 ohms.
5. Hook up the ohmmeter leads to relay terminals 3 and 8. Your metre should show a reading profit fast to 95 ohms.
6. Hook up the ohmmeter leads to relay terminals 6 and 7. Your metre should show a reading price hurried to 35 ohms.
7. Hook up the ohmmeter leads to relay terminals 1 and 2. Now your meter should indicate an infinity reading or no conductivity.
8. Hook up the ohmmeter leads to relay terminals 1 and 4. Jump terminal number 6 to the negative terminal on your car battery using a jumper wire and momentarily apply battery voltage to terminal number 7 using another jumper wire.2. Locate your ohmmeter to peruse within the 100 ohms span.3.
Jump terminal number 5 to the negative terminal on your car battery using a jumper wire and momentarily apply battery voltage to terminal number 7 using another jumper wire. Your ohmmeter should indicate a reading of 0 ohms.
10. Compare your results with the reading values given in steps 3 through 9 above. If your results differ from these values, replace the control relay.
