Thanks for the response.

I need to update my signature. The car now has 247k miles.

I've had the car for the last 11 years and have kept up on the maintenance. All suspension components have been replaced, plugs/wires/cap/rotor within the last 20K miles, all the brakes, exhaust... in a word, the maintenance is and has always been current. I haven't checked the codes -- I need to build the code reader first. In the last 6 month I had a problem with the OVP Relay. I replaced it and all was well.

The fuel pump behavior makes fuel deliver a suspect. How is the pump pressure regulated at start up? Does it reach a set pressure or is it timed? Where is it regulated? Internally or is power cut to it by a pressure switch at the fuel rail?

Thanks in advance.
