Hello everyone!
I'm new to the forum and this is my first post, though I'm confident y'all can help me with it.
Driving in my 1993 4Runner V6 the other day and I started noticing some sputtering. The gas tank was full. The sputtering started getting worse, like it wasn't getting the proper amount of gas, then I started to turn around to get it back home and it just quit. Like it wasn't getting any fuel.
It's got plenty of power. It tries to start. Just no fire. I turned the ignition to the accessory position to see if I could hear the fuel pump priming, but didn't hear anything. Not sure if I should hear it though. I've never listened to one before.
I'm thinking my fuel pump went out. Though I'm completely new at this, so I'm wondering if you have any other ideas or suggestions?
If you think it is the fuel pump, what's it look like to change that? Everything I'm seeing is there should be an access panel to it from the back seats, no? Taking out the seats and carpet seems like a pain and I want to make sure that's the best way before I start tearing things apart.
Thanks in advance for the help!

. First let's make sure you've got a fuel issue - open your air box and shoot a little bit of starter fluid or carb cleaner up the intake while somebody cranks the motor, if it catches and runs for a second then you know it's a fuel issue. Next, crank the motor again for a couple seconds, then put on some safety glasses and crack the fuel filter on the engine side of the fuel line. If you get a vigorous spray, then you know your fuel pump and fuel filter are probably good, and you can troubleshoot the injectors. If you get a weak spurt and dribble, close it back up and check it on the fuel tank side of the filter - if there's good pressure there, it's a fuel filter issue, easy peasy. If you still have no pressure on the tank side of the filter, then you know it's a fuel pump issue, but you still don't know if it's a bad fuel pump - it could be a bad Circuit Open Relay or AFM. To test for that, you're going to find your test connector and jump the fp and b+ terminals (I think your diag port is under the hood on the passenger fender, Google it to be sure). Once you've got those terminals jumped, try and start the truck again - if it starts, you've got a bad Circuit Open Relay, a bad signal from your AFM, or a bad ECU, in roughly that order of probability. If the truck still won't start, you know those are all good and it's almost certainly a bad fuel pump.
