  1. By the way, I did replace the valve cover gaskets about a year ago. There was no oil on the garage floor but the car had a smell of burned oil when my wife parked in the garage. A small amount of oil was leaking onto the exhaust manifold. So, I was aware of what needed to be done to get to the fuel pressure sensor. Yes, maybe an hour to get to the sensor and another hour to put it back together.
  2. I am pretty good at figuring stuff out. The fuel pressure sensor was a long shot. I don't think Florida heat had any more to do with it than any other place. The sensor is buried at the back of the block. There must be a diaphragm of some sort that regulates the ohms. The old and new sensors did not vary much when I connected an ohm meter to the leads. At that point I was thinking that I was on the wrong track but once installed and everything put back together, the car has run perfectly for 500+ miles. Once it started, I knew everything was going to be OK.
  3. I saw a YouTube video that had this same problem that I was having. It was broken English in the title but no words in the video. i had no engine codes, no check engine light but the starter would not even attempt to turn over when trying to start. The diagnosis was the fuel pressure sensor which is located at n the back of the engine. To get to it you have to remove the air cleaner and the intake manifold, and then the aluminum manifold in order to get to the sensor. Thesensor is $400+ at a lot of websites but on Amazon it was $19.95. You also need a 12 mm crush washer, $7 at Toyota or 10 for $6 on Amazon! i was sceptical that it would work but for a couple of hours of time and $20, it was worth a shot. The car started and ran rough for a few seconds, then died...at least the starter was working. Tried again and the engine cranked and with a couple of pumps on the pedal, it caught and is working great. The fuel was drained from the fuel rais and needed to be primed. So far, so good. Steve
