If everything is correct, we need to confirm the engine is getting spark and fuel. The easiest way to do this is to simply see if it will start for a couple seconds using starting fluid.

One last question. Was the vehicle running prior to replacement of the throttle body?

Let me know,

Welcome back:

What determined the throttle body was bad? It could be an issue with the fuel pressure, ignition. Have you scanned the computer for trouble codes? Based on your description, it sounds like it wasn't getting fuel. Since it now cranks and doesn't start, take a look through this link. It discusses the most common causes of a crank no start condition.

What I would like for you to do is check if the engine is getting spark and fuel. Here are links that show how to check:

You can follow the links to check or simply do this. See if it will start for a couple seconds if you use starting fluid. It if does, then we know it is fuel related. If it still doesn't start, chances are there is no spark and it is ignition related.

Here are a couple links you may find helpful when checking for spark:

Here are the manufacturer's specs for fuel pressure:

Fuel Pressure .................... 379-393 kPa (55-57 psi)

Let me know what you find.

Take care,
