Sideshow: I tore down everything to see if I missed a connector. Could not find any problems. When I took off the throttle body, I smelled fuel which indicates it's getting fuel. How do you check for the injector pulse? Thanks so much in advance!

All, Thank you for your help. I believe the problem is not the TPS - as you may have suspected (something else). To explain, I was changing the valve cover gaskets, removed/cleaned the throttle body, accidentally removed the TPS and put everything back together & it didn't turn over. I was...

No, there wasn't any tension on it when I applied it. I was following the service manual directions: 1) Place sensor at approximately 45 degrees (on the opposite side) and turn clockwise until there is no resistance shown on the voltmeter. 2) This was done with the throttle part open...

Shikra, My Dad has similar issues (Brakes-something dashboard blinks, tailight malfunctions). I thought initially it was the famous 'trunk wire' short, but, to my surprise the wires were intact. My only thoughts are that there's a bad ground or short due to a past accident. My Dad's LS...

Hello, I have a 90 LS400 with 108k miles (engine and transmission are in great condition). I recently "flushed" out the tranny fluid (Toyota T-IV) using the "cooler line to radiator" method. After flushing, I tried driving it, but, as you know you have to slowly shift gears back & forth to...

I recently bought a 90 LS with 108k miles. Previous owner claims that timing belt was changed. I am guessing that the water pump was replaced as well. There are no service records for these items. Is there a way to physically check if the parts are newer or replaced? I know I can probably get...
