  1. Good Evening, Fuel pump ECU, in the driver's rear seat side panel. Good Luck B)
  2. Good Evening, Please check the lower control arm bushings before replacing the rack. Get the Daizen poly units, they're the best. After I replaced ours (A full Saturday's project) the car didn't need an alignment, and it tracks like it should. Just follow the instructions exactly. Good Luck B)
  3. Good Evening, We just got our 92 SC400 out of the body shop yesterday. Full body, partial disassembly, lights polished, etc. Looks like new. 21 hours labor, ~$300 in paint, window tint, some seals and new emblems $3300 I'll try and post some before and after pix. Good luck B)
  4. Good Evening, Let's look at gasoline for a moment. Octane is basically how long the fuel burns; higher number, burns longer, makes more horsepower. Lower number; burns faster, pings. If your vehicle owner's manual specifies an octane rating of 87, running on gasoline with an octane rating of 89 or 91 or more will normally not make a difference. However, there are some exceptions to this, and it must be noted that if the owner’s manual specifies using gasoline with an octane rating of 89 or 91, then that’s what you should use because that’s what the engine is designed a
  5. Good Evening, I'm fighting the same problem. The ISC (Idle speed control) valve is under the Lexus symbol on the intake manifold. It's a round, black item with several hoses and an electrical connector. Here's the trick: Three of the hoses are coolant lines. You have to remove the wire cover, one large hose from the intake snorkel, and then the coolant lines. The valve itself is a stepping unit. This means you have to apply power to it, then ground two different terminals to move the valve. I'll be pulling mine off this weekend, to check and clean it up.
  6. Good Evening, Since my last post, the problem came back. Replaced the fuel pump ECU, good to go. Thanks AW3, he called it some time ago. As to why - When the car gets hot, the fuel pump ECU is supposed to increase fuel pump pressure and overcome fuel perculation in the engine. Bad ECUs don't do that. But relieving the pressure in the tank will allow you to run sometimes. Troubleshoot the ECU before replacing the fuel pump. In eiter case, the entire rear seat comes out. Good Luck
  7. Good Evening; Couple of questions (in order): - Is it hot outside (near 100F), or is the car sitting in the direct sunlight? - Is the clip that holds the fuel lines to the driver's side fenderwell broken? - Have you checked the valve in the fuel cap? It could be vapor lock, where the gas vaporizes in the fuel line and the air bubble won't let the fuel pass. I had this problem, solved it by reattaching the lines to the fenderwell, and wrapping the lines with foil. Hasn't happened since. I'll take a stainless heat shield and modify it later, and mount it to
  8. Good Evening, Lexus uses good 'ol normal oil. 10W30 recommended for older cars, or if you live in a warm climate. Filters range from the cheap generic brands (~$3) to the premium specialty ones ($9-15). You get what you pay for. Generally, Toyota/Lexus filters are in the $5-7 range, and are very good at their job. Tires are like shoes: What do you need them to do? We replaced our Michelin pilots with Toyo Proxes TPT after reading the reviews at They are quieter, smoother, and less expensive. Timing belt replacement is 90K. Strongly recommend the water
  9. Good Evening, The major parts of an A/C system: - Compressor (Motor driven part) - Receiver/drier (Temporary storage and removes moisture) - Expansion valve (Regulator - controls rate of gas flow) - Condenser (Gets rid of heat. Sits in front of radiator) - Evaporator (Where the gas expands and removes heat from interior) There are other minor parts and variations on this theme. When an R12 system is converted, most people take the cheap way out: remove the old gas, stick in the new. This can cause several problems: - Dessicant in the dr
  10. Good Evening, The conversion process has some quirks. R12 and it's lube oil is not compatible with R134a and it's lube oil. A do-it-yourselfer that gets air in the lines will blow the compressor because "air doesn't compress". On a '92, the low port is on the compressor, the high port is in front of the radiator, sitcking up through the plastic shroud. Get the angled adapter for the high port. The receiver/drier is by the driver's side headlight. Often, the conversion to R134a will seal small leaks in the system. Part of this is the conversion itself, another i
  11. Good Evening, Any A/C work should include a conversion to R134a. R12 is just too expensive. I converted mine with a new receiver/drier for around $125. The new part is best because you want all the old oil out of the system before the conversion and also the ability to get any moisture out after. SC300 are 15" stock wheels, SC400s are 16" Look within the SC forums for common problems, tips and tricks. You may find you have more items to look at. Many small shops can cost less $. Something to check first is that they're using the same parts, and the warranty on thei
  12. Good Evening, Welcome to SC-ownership. There are many places to look for parts: - eBay - TAP recycling in California - Right here in the forums - The local Toyota dealership, if they will work with you The needles can be replaced for as little as $99. The dealership is closer to $800, or more. The popular refurb place takes three days to turn your cluster. The A/C system might be a low-cost fix. I replaced the receiver dryer and converted to R134a for around $125. It gets cold. You can just convert the gas, but because the compressor oils ar
  13. Good Evening, The starter sits in the top of the motor, at the base of the "V", in the back. Blower or not, the whole intake manifold has to come off to get to the starter. Not much fun in either case. I have an '02 Tundra V8 with the TRD. The LX470 needs some additional procedures, making it slightly harder, but the same blower fits both motors. Three big points - Use premium fuel; don't add an FIPK intake; and buy an extra serpentine belt. Hopefully, I'll add one to my LX470 before they all disappear. Good Luck :D
  14. Good Evening, The flashing light is an error indicator. Check the compressor clutch connections (power and the ground), first. There are procedures in the factory repair manual to enter diagnostic mode and read the codes in the climate control system. This will save you a lot of time. Good Luck :D
  15. Good Evening, I work in a small Toyota dealership, in the service department. We service any Lexus we can, exclusive of warranty repairs (Because we aren't authorized) I personally own two Lexus (SC400, LX470) and two Toyota trucks (Tundra V8 and Tacoma 4cyl) There are many ways to save money, since many of the parts are the same. For example, the water pumps from all V8s interchange. Timing belts, serpentine belts, seals, etc. Buuuuttt, oil filters are different... We stock the part numbers for Lexus filters. We install genuine Lexus parts when needed, and we
