That's what I am thinking. Going to have my fuel pressure checked, and scan/log my car with the free PCM Communicator program to make sure first. If it is the fuel pump, should I go with the Walbro 340 in tank fuel pump?

I would definitely check your fuel pressure w/ a gauge. Then, check the injectors w/ a Noid light before I went through the trouble of a fuel pump. But checking the pressure will also let you know for sure.

What about your fuel pressure regulator?
