So today I remove my fuel pump from the tank to see if it works- i hook it to a battery and voila it does in fact work! But just before removal I turn my key to "on/run" and no fuel pump operation... even when B+ and Fp are bridged! I reinstall the fuel pump as I know it works.. turn the key to...

First time I saw this code I had a very dirty camshaft sensor. I have also seen code 13 when my new timing belt slipped a tooth after faulty installation. Pinched wires are a sensible culprit.. pinching or crimping wires between metal or plastic parts can be easily missed by accident. Lastly it...

Changed my 20amp EFI fuse b/c it was blown so now I have indicator lights and spark. But definitely no fuel. I will have to look into my fuel pump and or fuel filter next.. its all I can think of. But I dont know why it would work intermittently.

Madmont you may be correct about my ecu! Today again I started the car and it did not run very long at all!! So I checked to see if there was spark and behold I have nothing! So I find it strange that I am able to start the car after waiting some time hours but not directly after it dies. Does...

I dont know what 'inside the boot is?'.. but I assume you are looking from the rear view of the fuel tank. I also have a 904hundred and you are right there is a plate on the backside of the fuel tank that i believe is the electronic float for the fuel guage. There is a plate on top also if I...

This is a relatively easy procedure. Remove the rear seat and backrest. Directly in the center of the fuel tank you will see a metal plate with 8 or so small bolts. Remove this plate and this will give you access to the fuel pump. Carefully remove the fuel pump and associated parts. You will...

The engine will start and run not immediately after dying but will start and run after about two or three hours only for a short while again. It does not stay running at all after dying! When I have it running I can unplug the AFM and it will continue to run yes.. but I cannot accelerate at all...

My car no longer throws the code 25/26 instead it brings up 24 after dying. So it is my understanding that my air intake temperature sensor will cut off my fuel supply and regardless shouldnt I be able to bridge B+ and Fp in order to bypass the AITS fuel pump cutoff and keep the vehicle running...

My car throws a check engine light and code 25/26 air/fuel ratio lean and rich and cuts off my fuel supply! So I checked and swapped both precat o2 sensors and it makes no difference. I have loud exhaust leak after the cat where it connects to the pipe before the sub o2 sensor and also @ the...

On my newly installed used engine w/ 50,000miles the low oil pressure indicator light is triggered on the dash. I checked each rod bearing and it looks brand spankin new but when tightened back onto the crankshaft there is a little side to side play (movement) on each rod and I know this isnt...

It turns out that I had a faulty 02 sensor that needed replaced- this problem actually cut off my fuel supply. I found that the fuel pump is directly in the middle of the fuel tank visible only when you remove the back seat.

It is very probable your timing belt slipped a few teeth. Usually you will have diagnostic codes if your timing is off alignment. Pull the distributor covers then align your crankshaft mark to 0 and see where your camshaft markings align. Personally I dont assume that your engine idles low...

There are sensors on the underside of both camshaft/timing belt sprockets and below the crankshaft/timing belt sprocket. I am certain these sensors control tach readings. But i would suspect if your low idle shakes the car that not all of your spark plugs are firing. Do you have a CE light on...

If I have CEL fuel/air Code 25 and 26 and my car wont stay running does this mean the fuel pump is faulty? I cant hear the pump because I dont know where to find it on the gas tank inside the trunk. There is very minimal pressure through the gas lines and the fuel filter itself. I double checked...

I have removed my oil pump on the LS400 w/ front sump several times by simply removing the oil pan and unscrewing oil pick up pipe and related screws. However on the studs that connect the pick up pipe one of them has to be removed in order to pull oil pump straight off. Probably not the same...

Interesting. Where on the lexus.com website can you register your car? Then order a free owners manual?

Moderators feel free to clear any of my aimless posts hah hah

Jesus Christ! :zx11pissed: Nevermind. Four plugs not firing! The 1uz is amazingly smooth for just running on 4 cylinders:squint: . Anyway its not firing from the drivers side distributor. timing is perfect and the spacer is likely suppose to be there i assume.

Timing Belt Marks I almost forgot- Considering I have been working on and replacing my old timing belt on my new engine.. I kind of figure that could be why my car is sluggish and perhaps my flywheel and torque converter are fine. The damned thing is I only have the markings for each of my...

I am in real need to know more information about my flywheel. I installed my ls400 1uzfe flywheel on a new sc400 1uzfe. First I removed the flywheel from the ls engine and directly bolted to sc engine with 8 bolt plate on outer side of flywheel.----after doing this I went back to my ls engine...
