The car starts and then immediately shuts off.

Hi,

This could be the result of a few things. By chance, have you checked fuel pump pressure to see if it is weak? Also, do you notice that it stalls immediately when you release the key from the start position to the run position?

Fuel pressure is a common cause. Here is a link that explains in general how to check fuel pump pressure. You will need a fuel pressure gauge, but most parts stores will lend one to you.

I attached the manufacturer's fuel pressure specifications below.

Let me know. Also, let me know if the check engine light has been on and if the computer has been scanned for diagnostic codes.

Take care,

Joe
