You may not have done anything, Daniel.....
Any warning horns?
Engine Serial Number?

Thanks for sending me the serial number.
It's always wise to start with the BASICS: Compression (test), Spark (test), and Fuel/Air Pressures (test).
Also, take a close look at the belt and tensioner... make sure that they're intact and undamaged.

Don't forget to check for SPARK on all six cylinders. If you don't have an appropriate spark tester... you could at least attach a timing light to "one plug wire at a time" while the engine is running (watch for the light to flash).

DEFINTELY a good idea to follow this thread if you feel you're having a similar problem.
However, it would also be a good idea to post a NEW thread, with a complete description of what your engine is doing.

well i ended up melting #5 and 6 injector not sure what caused them to fail but i tore up a lot of thingsbut in the end insurance cut me a check for 6800 they said my motor was well maintained no water in my fuel and oil in motor so it pays to take care for your stuff
Wow, what kind of insurance do you have? Its hard to find one that covers mechanical failures as well!
yeah i want some of that insurance too.i blow mine 3000 out of pocket.
