How do i replace the fuel pump on a 1999 v6? Is it overly complicared? Thanks!

 

You need to drop the fuel tank. It is easier if it is empty. Soak the strap bolts with penetrant, and get a wire brush on the rusty threads before attempting to loosen.

Take precautions around the gas fumes. Disconnect the battery.

 

Took my mechanic 2 hours to get the bolts off and they needed replacing anyway...Go figures.

Not TOO hard. Just time consuming...If it will start and run I suggest running it out of gas if it has a lot in it. Otherwise that tank is gonna weigh quite a bit...(my tank came in at 150lbs with only 10 gallons in it)

Good Luck...Get the repair manual if you don't already have one.

P.S. Don't forget to change out the filter under the side door and check the one in the engine.

 

Gawd I hate fuel pumps. On my truck, I pulled the bed off to avoid dropping the tank. In Houston, Texas, rubber only lasts 7 to 10 years. If your vehicle is older than that and you drop the gas tank, be prepared to replace every piece of rubber!
I'ved owned my '91 B250 for only a short time. The gas gauge hasn't worked since I got it. The sending unit for the gauge is part of the fuel pump... I don't think you can get one OR the other. It's a combo deal. The van runs, so the pump is pump'n. When it goes

I may seriously consider cutting an access hole in the cargo floor to swap the pump and covering it with a custom plate.

The fuel pump always goes out with a full tank of gas, doesn't it?

Thanks for the responses I'm going to start on it tomorrow morning. Just a few more questions....
A mechanic told me I needed the new fuel pump but when I turn the key over I hear it come on and it sounds good not making and funny noises. But I have a lot of trouble starting it in the morning and low fuel pressure also a random misfires? Anyone still think its the pump? Or something else... thanks!

 

Interesting. The last two pick-up truck fuel pumps that I had to replace just quit. Not intermittent, no surging, just done. While working properly, I could briefly hear the whir of the pump upon turning the ignition key on but not all the way to start. When the D150 fuel pump went, I squatted down, held onto the bed and kicked the ever love'n heck outta the plastic gas tank near the pump a few good whacks. The pump came back on but only briefly.

In the B250 cargo van, I can hear that sucker all the time.

So, unless there's damage to the impeller part of the pump, if you hear it making the same sound it's always made then I'd think it should be pump'n.

When's the last time you swapped in a new fuel filter(s)?

Try the filter and check the coil first. My van was missing and acting weird. Changed the coil and that issue stopped. Altho it ended up I did need a fuel pump a few weeks later...Now just a transmission...Oh and an O2 sensor that my mechanics 18 year old helper broke (don't ask...the kid is always breaking the wrong things, he didn't even get the bolt loosened).

 

There is no external fuel filter. The filter is a part of the fuel pump assembly inside the tank.

 

Bummer that the filter is inside the tank!

Other than fuel pump, filter, O2 sensor, ignition coil, or even the main computer or electrical grounds/connections...

In my experience, ignition coils aren't prone to intermittent failure. They just go. Newer "ignition control module" type things of anything with a dang circuit board however, can.

When's the last time you had a tune up? Even if your 99 is computer controlled ignition, plugs and plug wires need to be replaced every once in awhile. I've had to replace fairly freshly installed spark plug wires that were sitting against hot engine or exhaust components, seriously degrading the composition and performance of the wire.

And both of my early 90's Dodges EAT distributor rotors and caps.

Vacuum leaks can also seem like fuel or spark issues.
