Hi,

Does the check engine light stay on while the engine is running? If so, the computer should be scanned first for diagnostic trouble codes.

Here is a link that explains how it's done:

Since it stalls shortly after starting, it could be related to the fuel pressure also. That would likely be the next thing I check. Here is a link that explains how it's done.



Start with this and let me know what is found.

Take care,

Joe
