Car will start but as soon as I put in drive it shuts off. Have a problem with MAP sensor location and if it is wired properly. also, the EGR valve had no vacuum hose attached which was part of the problem. Thanks for your input.

Does it shut off in reverse as well? You could have a torque converter that has a problem and has locked up, the clutches inside fall apart and make it so the engine cannot free wheel. Please upload a short video here in your response to the problem so I can tell for sure what's going on. In the meantime, this guide can help us get started on checking the easy stuff to hopefully get you going:

And you could have a vacuum leak as well.

Let us know what happens and please upload pictures or videos of the problem.
