First, locate the main relay of your car’s engine and remove it.
-
Find the battery positive terminal and attach it to the number 4 terminal. On the other hand, the battery negative terminal must be attached to the number 8 terminal of the main relay. Now, check continuity between the number 5 and the number 7 terminals. If there is continuity, proceed to the next. However, if there is no continuity between terminals number 5 and number 7, then replace the relay and test it out.
-
Since there is no continuity between number 5 and 7 terminals, you’ll have to attach the battery positive terminal to number 5 terminal. On the other hand, attach the number 2 terminal to the battery negative terminal. Now, you have to check for continuity between number 1 and 3 terminals of the main relay. If again there is continuity, proceed to the next step. However if there is none, replace your relay and test it out.
-
Lastly, it’s time to attach number 3 terminal to the battery positive terminal while the negative terminal should be attached to number 8 terminal of the main relay. Now, it’s time to check continuity between the number 5 and number 7 terminals again. If there is, then this means your main relay is not the problem. It means it is working just fine. There are other things to check like the fuel pump or the wiring harness towards the pump. If there’s no continuity, then you should replace your main relay and then test it out.
