My car starts runs for 5-10 seconds then dies off like its starving for fuel. I have changed my fuel pump and replaced all 4 spark plugs and so far no luck.

Hi,

Have you checked the fuel pressure to make sure it is within the manufacturer's specifications? I realize the pump is new, but it may still be off. If you haven't, here is a link that shows how it's done.

Now, when it stalls, does it start right back up for you or do you have to wait? Does the check engine light stay on for the 10 seconds that it is running? Have you noticed any smoke from the exhaust or odd odors when it runs?

Let me know as much as you can. I'm questioning if the fuel pressure is correct, and I am also questioning if the crankshaft position sensor could be failing.

Take a look through this link and let me know if it mirrors what you have experienced:

Let me know.
