Hello. Thank you for using Just Answer. I will give my best efforts in answering your question to achieve your full satisfaction.
To bypass the fuel pump relay...
You will locate the relay in the electrical box under the hood.
Remove the relay and look on the bottom of the relay. You will notice that each pin has a number assigned to it. In the fuse box, jump pin 87 to pin 30. This will activate the fuel pump.
I mean relay number 14, the f/p relay shown in the diagram. Next to the pins on the relay, there should be numbers that identify the pins. You will use a jumper wire, paper clip... to jump pin 30 to pin 87 in the slots that the relay would go into in the fuse box.
They go together more than you realize.
Next step is to see why the vehicle is doing what it is doing.
So... Give me a story of what the vehicle is doing, how long it has been doing it, what you have done to it so far, and we can take it from there.
Does the fuel pump energize with out jumping the relay?
The pump is running.
Disconnect the MAF sensor and see if the condition improves.
The MAF sensor is located on the throttle body # 3 in the picture. Unplug the sensor and see if the vehicle runs better.
