That such a friend if you checked the sensors and are fine because of the comment you mention in which it is heated from my point of view can be the catalyst that this cover takes a look, it is a classic failure.
Also check your gasoline filter.
The injection system what type is if it is vortec you have to change the bomb for the Vortec if you bought for another type that is your problem.

Hello,
I tell you what the problem was, the wiring at the crankshaft sensor entrance were broken and made short in a circuit inside the computer, this affection with the signs to other sensors, such as the camshaft and oxygen tree, when changing these sensors would never be improved by what this cycle had to be repaired, thank you for your comments that were very recommended by their recommendations to discard the possible faults.

Hello, finding the solution and having published it has been good news for most mechanics, almost all of us thought that this sensor would not give that failure, if of course, impossible engine start, power failures in power and combustions such as a cylinder or more do not work etc. This is how we learn a little every day.
All the best.
