Guys,
I'm trying to figure out why my car won't start. Starter spins fine, got one small sputter of ignition after I replaced the fuel pump last night, then nothing. I have been a bad boy and not replaced the fuel filter. It has 89k miles now. I've been to two local shops and nobody seems to be able to locate the filter. The earlier cars had it down on the driver's side frame rail, but I think I've search this site and the whole 'net, and not found where it is. I have some pressure now, so maybe it's not the filter. Need to check for spark now - I know, not very logical of me. This car has been so trouble free, I'm frustrated as to why something like this might happen, and of course it's a few days before an important family trip on Friday.

Thanks,
Rob

I think you did not install the pump properly and the line has an o-ring that if not placed properly will clog it.

Hi!

I recently changed my fuel filter and it only takes a few minutes (under 20).
It is located up on the body in front of the rear differential. Very simple and I noticed more power. The old one was almost clogged. I have 145K on my silver one.
The toyota part number: 23300-50060
This is for a 98 ls400

Good luck

I have an 1996 LS 400... looking for a DIY (with pictures) on how to replace the fuel filter? thanks!

floresea, this should help:

While the tutorial and pics are for 90-94, it should be very similar for you 96. Pull the fuel pump fuse and start the car until it dies.

floresea

is it the same fuel filter location for a 1996 LS400?

(the local dealer quoted me $200 to do this job.... if it really only takes a few minutes to DIY, then I might give it a go...?)

yes,
you want some 17mm wrenches for the job. i recommend a flare wrench so that you don't screw up the pipe fitting on the hard line.

floresea

hmmm... searched through the 1996 LS400 Service Manual, and the only mention of the Fuel Filter shows the location to be next to the Fuel Pump... please see attached pic...

floresea

do you know the torque value for the installation? thanks

no leaks!

I think I found it. I guess the previous picture I posted is for the 2nd Fuel Filter which is part of the Fuel Pump Assembly. The Fuel Filter is located to the Right of the Rear Differential.

As you can see from this picture, I don't think the Fuel Filter has ever been changed (I have almost 230,000 miles on my '96 LS400). All that corrosion on the filter fittings is making me think twice about attempting to do this job myself...

My '96 LS400 has more miles than that and the underbody looks like it has 10,000.

I would NOT touch that fuel filter if I were you. Maybe have a shop do it.

My thoughts exactly... my car's 2 previous owners were from the East Coast (NJ/NY).... so that explains why the underbody looks so rusty.

I've had it for 8 months and haven't had any issues... I did do the 90k maintenance on it as soon as I bought it though (timing chain, water pump, etc.)... and I even drove it across the country from MD to CA recently... so considering I have spent ~$5k total (purchase price + major service) for an LS400 with excellent interior/mechanical condition, I think the car has already paid for itself!

I actually just found a local shop that will do the fuel filter replacement for $112 total (parts/labor/tax), so I'm hoping they won't have too much trouble with it.
