Hoping you guys can give me some new insight on this problem.
I have a 2009 Toyota Corolla 1.8l with 217k miles. About once a month it would not start unless I cycled the gas pedal through the full range a couple of times. A few weeks ago it would not start at all no matter what I did. I exhausted my diagnostic capabilities and suspected a sensor or ECU problem so I had it towed to the dealership.
They had it for a week and decided it had to be the remote start that I installed. I stopped by to unplug it for them and they had the valve cover off and plugs out. The removed they remote start and put new plugs in it and got it to start finally. It was running a little rough and did not want to cold start.
They suspected bad gas so ran it dry and added new gas plus injector cleaner but nothing changed. They removed the fuel rail to check fuel pressure and clean the injectors directly. They also performed a compression test and measured 140psi on each cylinder. I am not sure if that is dry or wet. The book specs 157 to 190 psi. They decided low compression is the cause of the cold start problem but it will eventually start and run okay. They replaced the battery claiming mine was bad, likely form all of the cranking during diagnosis.
I picked it up and it was difficult to start. The service adviser finally got it to start. I left for home and it started idling rough at stops and required some gas to keep the RPMs up. It then completely died about 10 miles from home and would not restart. It finally threw some engine codes, misfire cylinder 4, fault in primary or secondary ignition circuit on all 4 cylinders.
I would like to get it running so I can trade it. Would a leak down test be a good next step or should I be looking for something else? I am surprised that the compression only being 20psi off would cause a start and idle issue versus just some loss of power.
Sorry for the long post. I am stumped and a little frustrated by the dealerships diagnostic process. For the tractor related, I moved it around the drive with my Ford 860.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
