While driving vehicle inadvertently caught on fire. The cause of the fire was undetermined.
After running the vehicle and shutting it off for about 2 hours the vehicle did not want to start, there was only about 2,000 miles on the truck. The starter is cranking the engine, but the engine is not starting up. I took it to the Toyota service department, and they said nothing was wrong with the vehicle. The same thing happend severl times after I had taken it to Toyota. The only way to start the vehicle would be to crank it up for about 5 minutes, then the vehicle would run rough for about a minute. I took it to the Toyota service department again and this time they worked on it. They said they had to change the throttle position sensor, the engine wiring harness, and the fuel injectors. No old parts were available. Problem has still not been corrected. Vehicle now has about 6,000 miles and every 3-4 days it still doesn't want to start up.
