Hi all
The car is a 2000 Toyota Celica GT Automatic (Engine: 1.8-liter DOHC 16-valve VVT-i 4-cylinder, Mileage: 133000 miles)
This starting happening 7 months ago. I was idling at a red light when my car starting shaking violently and the engine cut off shortly after. I immediately tried to start it up and while the car did start, it cut off after about 2 seconds. I tried to get it going several times and eventually called a tow truck. When the truck arrived 45 minutes later, the car started up fine as if nothing had happened. This went on for several months. It didn't cut off while idling but once every 1-2 weeks I'd go to start it and it would start but cut off after about 2 seconds. If you let it sit for about 30-45 min though, the car will start up fine.
It only really acts up when I have a lot of errands to make and I'm constantly turning my car on and off. Most days the only driving I do is to and from work and since the car has a chance to sit for 8 hours it has never had problems to or from work. I didn't really start to worry until 3 months ago when the car starting cutting off while I was driving. I could be accelerating when the car would just shut off. Almost as if I had pulled out the key. The gas pedal goes unresponsive and I coast to a stop. Then it goes back to starting up and cutting off unless you let it sit for a bit.
I've seen people posting similar problems on various sites but most seem to be able to keep their car running as long as they held the gas pedal down. This has only worked for me a couple of times. I was able to hold the gas pedal down, let the car run at about 3500-4000 rpm's and after about 30 seconds I could let my foot up and the car would stay on. Most times though if I give it gas, the engine revs up and will die back down.
I've since taken it to a mechanic but I've been there 3 times in the past 6 weeks and the problem still exists. My dad put a new battery in and on the first visit to the mechanic they replaced the positive and negative clamps that secure to the battery and flushed the idle control valve. The second visit they replaced my fuel pump, strainer and fuel filter. On the third visit a week ago they replaced the idle controller. After the last visit the car ran superbly for week. The I noticed it started randomly dropping rpm's at times and when the fan came on it would idle roughly. Last night while idling in park it just cut off. No warning, no rough idiling. The only thing that clued me to it cutting off was my instrument panel lighting up. And I was back to square one. It would start and then cut off after 2 seconds. I had to let it sit for an hour before it started up.

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.
Every engine requires spark, fuel and compression to run. That's what we have to look for.
These are the basics that need to be tested and will give us the info required to isolate a cause.
1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.
2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.
