I need to locate the fuel pump relay for this truck. I am not getting any power to the pump and I'm told it could be the relay. Thanks

It doesn't have a fuel pump relay. The fuel pump is powered by the main relay under the right kick panel.

If there is no fuel pump relay. What else could stop power from getting to the fuel pump? Could it be the main relay or is there a kill switch or something else causing this loss of power?

There are any number of possible causes. The main relay could cause it but it would also take out the fuel injections. You may not even be testing it at the right time. It has to be cranking to see power.

I called the local parts store and they said they have a fuel pump relay. It is $61. Do you think they are trying to sell me a main relay?

I guess you'll find out when you go to install it.
