DIY on replacing fuel pump?

I have a 2001 Toyota Tundra SR5 sitting in my driveway for a little over a year now. It has a little over 400K miles on it. It needs a new fuel pump. Are there any recommended videos out there to see if this is a good DIY job for myself.

 

Before anything, some sanity checking:

How do you know 100% it's the fuel pump?

Which engine? V8 or V6?

The fuel pump only engages when the key is forward (engine cranking) or when the ECU gets signals sensor inputs the engine is running. That often trips people up when doing diagnostics, makes them falsely think the pump is bad. The ultimate way to know is to force the pump on and test fuel pressure.

What diagnostics have you done thus far? Have you tried jumpering the fuel pump on at the relay and testing for fuel pressure?

 

@shifty` is more meticulous and methodical that I am.

 

It wouldn’t crank one day after work. I have a mechanic right next door and he brought it over and told me it was the fuel pump

 

If its really the fuel pump, its a couple hour job and about $150 part unless you break any bolts off.

 

If you trust the mechanic knew about the interesting fuel system with these trucks, just make sure you buy a Denso brand pump, and don’t buy it on scAmazon or fleaBay lest you end up with a knockoff. You can look up the part number for your truck at www.densoautoparts.com

the job isn’t hard just maybe tedious dealing with the filler neck and associated lines, and if your straps are rusty. Dropping the tank is the easiest way to go about it. Depending on cab type, the pump is (I believe) up under the cab, so pulling the bed won’t help.

Not a hard job though, YouTube has plenty like that @Baller dropped above. You can do it.

 

You can always turn the key to "ON", crawl under the truck, bang on gas tank (like, on the center strap). Then get out and try to crank it.... I did that for a week or 2 before I replaced mine.

 

Classic way to resurrect fuel pumps for a little extra life! I've used this trick a number of times also for old pumps. Similar applies for failing starters/solenoids.

 

Hell yeah! I'd pick my son up from daycare and would be out there banging the tank like a madmen, but it works like a charm! It was a good day when my son said, "hey dad! the truck started and you didn't have to hit it with a hammer this time".

It sure did son, it sure did.
