Thanks for the information from earlier, so I need to replace the fuel pump since it has 25 psi. But why does it work for a few days and then it will not? It seems like something is cutting it off, does the vats have anything to do with the fuel pump? Like this weekend from Friday to about 2am Tuesday morning, I drove it to work Monday evening it wouldn't start up, cranked good, but no fuel pressure, then this evening evening when I got to work it started up just fine and it started up fine about an hour ago I drove it home?

Hello,

Yes the VAT system does cut off the fuel pump in this car, what happens is the ignition cylinder has two small wires that become weak and start to break. When the car wont start is the security light flashing? If so the wires are starting to let go which causes the problem you describe.

Please let me know what you find.
