At least once a month the vehicle will crank over but will not fire up to start. After 2-3 days it will out of the blue start first time. Fuel pressure is fine as we checked flow from the filter but no spark

Check both ignition relays in the underhood junction box, left inner fender.
Check crankshaft and camshaft position sensors, both for proper gap, installation, and to verify they have power. See attached image.

Just because you get fuel out of the filter doesn't mean there is enough pressure to allow the engine to run. You need to check the pressure.

Hey STEFO

This problem sounds like the crankshaft angle sensor is going out which is a common problem with those cars, here is a guide that will show you what you are inf or when fixing this problem.

2002 Toyota Landcruiser V8 All Wheel Drive Automatic 149000 miles

On three occasions in the last month, my Land Cruiser would not start. It would crank, but never kick in. First two times I waited a day or two and tried it every few hours. It would not start. I called a tow truck and when the truck arrived, it started and I drove it up on the tow truck. It always started at the dealer and then another toyota mechanic shop. Since it kept starting, they could not determine the problem.

The third time was this morning. I need to have it towed, but I guess it will be tomorrow.

Any suggestions on what might be wrong.

How frustrating this can be! You can try and retrieve any set fault codes, but I would think that the workshop would have done that, but try anyway. If no codes are set it is really hard to suggest anything that wont cost a $$ to check, you don't want to start throwing bits at it in the hope that you get it right, you can only really diagnose these problems while that are faulty, best guess, with no codes to go by, a faulty fuel pump, or Crank angle sensor.

My Toyota will occasionally not start but will crank, after it sit for an hour or two, it starts
and will run for a couple of weeks without incident, and then it happen again with the same results. No problems shows on the diagnostic tests. I have checked the fuel pressure and diagnostics shows no fault.

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.

I been having this problem for weeks. Sometimes the car works fine then when I turn it off and go to the store and come back I put the key in and it won't start. It makes the sound but won't get up. The battery is new
