I was going to say that too.

Mike: Couple things to check: Dynamic fuel pressure, and measure the current draw for both pumps (covered in Dynomites "sticky" section.

Pictured: Measuring actual fuel pressure while driving normally and at WOT. (FYI, fuel pressure at WOT should be ~54 or 55± a pound. Current draw should be between 8 to 10 amperes [with ignition switch OFF, and both the primary and secondary fuses installed])
